This is an imaging procedure that uses high-frequency sound waves to create images of the inside of the body. The instrument used in the procedure is called an ultrasound probe is. It emits high-frequency sound waves which bounce off different body parts creating echoes that are picked up by the probe and turned into moving images.

During the procedure, the image is displayed on a monitor. This scan can be used for monitoring an unborn baby, diagnosing a condition or guiding a surgeon during certain procedures. Sign In.

What is an ultrasound used for?

Types of ultrasound scans There three types of ultrasound scans and the type of ultrasound scan you have will be determined by the body part being scanned. External ultrasound scan: The ultrasound probe is placed onto the skin and moved over the body part being examined. A gel is applied to the skin to allow easy flow of the probe and continuous contact between skin and probe.

This scan is noninvasive and painless and the only thing you will feel will be a coolness from the gel being applied and the probe on your skin. Internal ultrasound scan: You will be asked to lie on an examination table on your back or on your sides with your knees drawn up.

The ultrasound probe with a sterile cover is gently inserted into the rectum or vagina and the images are transmitted to the monitor. This scan causes a little discomfort and if you feel any pain you should let your doctor know. Endoscopic ultrasound scan: This scan uses an endoscope that has an ultrasound device and a light on the end.

The endoscope is inserted through the mouth into your body to examine body parts such as the gullet or stomach. You will be asked to lie on your side as the endoscope is gently and carefully pushed down towards your stomach. Once inserted it is used to create images which are displayed on a monitor. You will be given a local anesthetic spray to numb the throat area and a sedative to keep you calm.

How do I prepare In some cases, you may be required to follow certain instruction to help improve the clarity and quality of the produced images. You may be instructed by the doctor to drink water and avoid going to the toilet until after the scan and to avoid eating for several hours before the scan.

What happens during an ultrasound scan? Most ultrasound scans are carried out in a hospital radiology department but they also are done in outpatient centers. An ultrasound scan usually lasts between 15 and 45 minutes. An ultrasound scan is performed by a sonographer or radiologist.Endometriosis is a benign gynecologic disease characterized by the presence of endometrial tissue outside the uterine cavity.

The complexity of the disease results from its multiple clinical presentations, the multifocal pattern of distribution of the lesions, the presence of extra pelvic sites of the disease mainly affecting the urinary and the intestinal tractsand the difficulty in the preoperative diagnosis by means of imaging studies and in the surgical treatment. The preoperative mapping of the lesions, either by ultrasound or by magnetic resonance imaging, allows for an adequate surgical planning and a better preoperative patient counseling, especially in those women with deep infiltrating endometriosis affecting the bowel.

Also, the choice of the surgical team that is going to perform the procedure may be based on the preoperative workup. In this paper, we highlight the important findings that should be described in the imaging examination reports for the preoperative workup of patients with deep infiltrating endometriosis of the intestine. Adequate surgical planning can be very well defined when there is a proper preoperative mapping of the disease by imaging studies, either ultrasound or magnetic resonance imaging MRI.

In this article, we present the rationale for the preoperative imaging assessment of intestinal DIE. Several imaging examinations have been used to evaluate the DIE lesions in the preoperative setting, including transvaginal ultrasound TVUSMRI of the pelvis, and transrectal ultrasound. InAbrao et al 19 showed that in women with DIE lesions affecting the rectosigmoid or the retrocervical area, TVUS had sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy superior to pelvic MRI and gynecological examination digital examination.

Similarly, Bazot et al 18 compared the value of the physical examination, the TVUS, the transrectal ultrasound, and the MRI in the evaluation of different locations of DIE lesions, concluding that MRI has similar results to TVUS and transrectal ultrasound for the diagnosis of intestinal endometriosis but has higher sensitivity and higher likelihood ratios for the diagnosis of endometriosis in the uterosacral ligaments and vagina.

Furthermore, there are two basic characteristics of intestinal DIE lesions: multifocality and multicentricity. The former is defined by the presence of other intestinal DIE lesions within a 2-cm area to the main lesion, and the latter is defined by the presence of other DIE intestinal lesions beyond 2 cm from the main lesion.

The success of the surgical treatment is related to the complete excision of the endometriosis lesions. This allows for an adequate preoperative patient counseling and planning of the surgical strategy. Patients are requested to fast for six hours before the examination and to maintain moderate repletion of the bladder.

Ultrasound gel is injected into the vagina 60 mL and the rectum mL to enable better visualization of the dome and the fornices of the vagina, the rectovaginal septum, and the spaces of the posterior compartment of the pelvis Fig. Scopolamine- N -butyl bromide, an antispasmodic agent, is administered intravenously immediately before the examination to attenuate uterine contractions and to reduce motion artifacts caused by peristalsis.

Precontrast imaging: Our standard MR imaging protocol includes the acquisition of axial, sagittal, and coronal T2-weighted fast spin-echo images for assessment of the entire pelvic anatomy and the pathologic changes and axial T1-weighted gradient echo images in and out of phase and with fat suppression for differentiation between blood and fat.

Postcontrast imaging: Gadolinium chelate Dotarem is administered intravenously followed by the dynamic acquisition of axial and sagittal volumetric fat-saturated T1-weighted sequences. Bowel preparation was routinely performed in our patients to ensure a better visualization of the DIE lesions. On the day before the TVUS, the patient is requested to have a low-residue diet and administered a mild oral laxative.

One hour prior to the examination, a rectal enema consisting of mL of sodium diphosphate is performed. Ultrasound gel is injected vaginally 60 mL to distend the dome of the vagina.A comprehensive collection of clinical examination OSCE guides that include step-by-step images of key steps, video demonstrations and PDF mark schemes.

Table of Contents. Ultrasound is a common imaging modality that allows visualisation in real-time. As such it is becoming increasingly popular on the wards for diagnosis and management purposes. You should be familiar with its operation and know in which situations it may help your clinical decision making. These sound waves are then reflected by different tissue types in different ways. Bonesfat and stones produce a hyperechoic signal.

A hyperechoic signal is bright as most ultrasound waves are reflected. Cartilage and muscle produce a hypoechoic signal. Fluid and fluid-filled structures produce an anechoic signal. An anechoic signal appears black as there is no reflection of ultrasound waves. A shadow may be noted on an ultrasound when a hypoechoic area is located behind a hyperechoic structure.

The first steps of performing an ultrasound involve:. Typically, there is a dot or a cross on the probe, this correlates with a dot on the left side of the screen.

Position your patient as you would when assessing the jugular venous pressure JVP in a clinical exam e. Identify the internal jugular vein IJV and the carotid artery, assessing the following:.

Slowly rotate the probe keeping the IJV in the centre until a sagittal view is achieved ensure you are not foreshortening the vein by carefully moving the probe medially and laterally.

Locate the point of the initial collapse of the IJV centre the probe over this point. In this section, we will be focusing on peripheral intravenous access, however, similar principles are applied for central venous line insertions. Ultrasound-guided IV access should not supplant intraosseous IO access in life-threatening situations. A high frequency MHz linear transducer is typically used as high frequency permits a better resolution of structures close to the surface of the skin.

Select a vein as per non-ultrasound guided peripheral IV placement.

Identify the target vein in the transverse plane: note the depth of the anterior wall of the vein and pay attention to any adjacent structures. Once identified, rotate the probe into the longitudinal plane. Hold the probe with the thumb, index, and middle fingers as shown, using the remaining fingers as an anchor.

FAST is used in emergency settings to rule out free fluid in the abdomen as well as pericardial effusions using a curvilinear probe. As discussed previously, fluid shows up as black, so the scanning clinician is inspecting for black lines surrounding organs. The ultrasound probe is positioned in the coronal plane in right mid-axillary line between rib 11 and Once positioned correctly, the ultrasonographer inspects for evidence of free fluid between the liver and the kidney.

The ultrasound probe is positioned in the transverse plane, within the sub-xiphoid region with the probe aimed at the heart. Clinical Examination. Eye Drops Overview.There is a proliferation of fake WiFi hotspots that hackers use to steal information.

ExpressVPN has automatic WiFi protection to defeat this scam. There is also a kill switch in the app. If you also want to access streaming video online, ExpressVPN is one of the best VPN services that you could use to get around international access blocks. CyberGhost offers a free VPN, however, it's worth paying the small fee for the Premium version of this VPN because that has better detection evasion methods and faster speeds than the free version.

CyberGhost's user interface is really cool and enjoyable to use. It has automatic WiFi protection and a kill switch to prevent your real internet address from being discovered. The account creation procedures of this VPN give you total privacy because they don't hold any personal details on you at all - you're identified by an account number.

NordVPN has servers in 61 countries, so look through the list and make sure they can get you around the access restrictions of Bet365. It is OK to bet from another country with Bet365, so if you don't see the location that you have your account in on the NordVPN server list, just pick a server in a country where betting is allowed and you'll be able to keep on gambling.

This VPN can work out really inexpensive. It gives each account holder an allowance of six simultaneous connections, so you have enough capacity to share an account with a friend. NordVPN is fine with that. There is also a very cheap two-year subscription option. However, you have to pay for the whole two years upfront. The government internet blocks save you from the risk of breaking the law. Different governments use different methods to block access to websites.

Some use a combination of techniques to block access to certain sites. In just about all cases, it is the Internet Service Provider (ISP) that implements the blocks. Everything you do on the internet has to go through the computers of an ISP. ISPs have three main methods to stop access to websites.

The first is address filtering. The ISP maintains a list of banned web addresses. If Bet365 is banned, the ISP simply drops any request passing through its computers that includes the address bet365.

On the internet, all computers are identified by an IP address. Some address filtering systems maintain a list of banned IP addresses. Thus, rather than blocking a request because it includes bet365.

The mapping between web addresses and IP addresses occurs at a Domain Name System (DNS) computer. When you type www.

It then sends a request for a page to that IP address. Some ISPs manipulate the DNS entry for banned web addresses in order to implement the bans. The usual practice is to set up a ban message page and enter the IP address of that against the web addresses of the sites that the government wants to block. The third method that ISPs use to block banned sites is content filtering. This is a good way to deal with governments that ban whole topics rather than specific websites.

In this scenario, the ISP reads the messages that it sends out onto the internet on behalf of customers. VPN operating methods manage to defeat all three ISP site block strategies.What do these numbers tell you. Your employees need to understand this. These reviews are just as important to your staff as they are to you. If negative reviews hurt your business, it could put your employees out of a job.

Engaged employees work harder. You can display these results on your website or social media platforms as well. How can you do this. The example above even tells the customer how long it will take them to complete the review.

You can design surveys that are shorter as well. I like them because they are simple to use. Surveys are a great way to get customer feedback in general. Using surveys to generate social proof is an added bonus. Yelp allows customers to include their name and a photograph for their profile. The reviewer, Chelsea, has a photo to validate who she is.

Her picture even shows her eating food at a restaurant. Images like this resonate more with consumers. They can also see that Chelsea has made over 300 reviews on Yelp.

People are using their full names and profile pictures to back up their statements. Images like that will have a negative effect on their credibility. Reviews that tell a story can have the same impact. So, how do you get customers to tell a story.

Bonnie reviewed a local pizzeria in Seattle. It was a personal story about her specific experience. Why was she there. What type of music was playing. Lots of Bob Marley. When did she visit. How was the service. All of these points are highlighted in the review.

Stories create a connection and generate social proof. You can also use: Experts Crowds Celebrities See if you can find an expert in your industry to validate your products. Use crowds to generate social proof as well.Working at the right tempo helps you stay in control rather than compromise strength gains through momentum.

For example, count to three while lowering a weight, hold, then count to three while raising it to the starting position. Pay attention to your breathing during your workouts.

Keep challenging muscles by slowly increasing weight or resistance. The right weight for you differs depending on the exercise. Choose a weight that tires the targeted muscle or muscles by the last two repetitions while still allowing you to maintain good form. If you can't do the last two reps, choose a lighter weight. When it feels too easy to complete add weight (roughly 1 to 2 pounds for arms, 2 to 5 pounds for legs), or add another set of repetitions to your workout (up to three sets).

If you add weight, remember that you should be able to do all the repetitions with good form and the targeted muscles should feel tired by the last two. Stick with your routine working all the major muscles of your body two or three times a week is ideal. You can choose to do one full-body strength workout two or three times a week, or you may break your strength workout into upper- and lower-body components. In that case, be sure you perform each component two or three times a week. Give muscles time off.

Here are ten tips to make your vacation the stress-buster it really should be.

If you only take a vacation once in a while, it puts a lot of pressure on that time period for everything to be perfect. A three-day getaway is nice and a week-long one is quite common, but 10 could be the magic vacation number. Traveling with kids adds unique challenges, especially when you have to schedule around nap and feeding times. All you need is some extra planning and preparation for a smooth trip. Most of us go the DIY route when booking our trips, but a travel agent can save you time and stress when you have a complex vacation planned, such as traveling with a group or you have health issues that need to be accommodated.

If you like crowds and long lines, visit a popular destination in prime tourist season. Otherwise, you might enjoy your vacation more if you head somewhere less popular, like one of these suggestions from Lifehacker readers, or take a staycation. Similarly, the summer might not be the best time for a vacation, depending on where you go.

You can plan a trip itinerary using your own custom Google Map or this simple spreadsheet too. Keep your cool by making sure everyone is on the same page when it comes to accommodations and planned activities. You can force yourself not to get sucked into work mode with a vacation email address. Photo by Transia Design (Shutterstock).

To come back this year, win a championship, it would be hard not to hang it up. The Great American Race is always about much more than horsepower and drafting. It is about being aggressive at the right time and taking advantage of the small holes that other drivers leave. The driver who does this bestand has no mishap with any aspect of the carhas the best chance to win.

Everyone has to shake off the rust at Daytona, and Earnhardt has more of it than most of his competitors. That's why we like Keselowski to emerge here and take the checkered flag. He can bide his time and should have an excellent chance to run the favorite down and capture the title. He will face challenges from Logan, Elliott and Harvick, but this should be Keselowski's race to win.
