Evaluating the liver with abdominal CT
When evaluating the liver on a CT study, you need to look out for steatosis, cirrhosis, solid masses, cysts, and hemangiomas. You should also check the vasculature—the portal vein and the hepatic veins. In this video, an expert radiologist shares his tips and tricks for liver assessment.
Distinguishing the imaging planes on abdominal CT
The most obvious difference between a traditional x-ray and a CT study is that a CT study contains multiple images that can be reviewed in three different planes—the coronal, the axial, and the sagittal plane. In this video, an expert radiologist explains when to use each of the planes.
Venous ultrasound course: identifying varicose veins in the insufficiency study
Ultrasound learners find it tricky to tell varicose veins from the great saphenous vein (GSV) and the small saphenous vein (SSV). In this video, you'll learn how identify varicose veins with confidence and what to do if you find a blood clot in a varicose vein.
Venous ultrasound course: deciphering DVT waveforms
A pulsed wave (PW) Doppler study is an integral part of venous ultrasound. This video explains how to interpret the waveform graph to find out whether a vein contains a clot, where the clot is located and if the patient suffers from venous insufficiency.
Venous ultrasound class: executing a DVT ultrasound study
Students benefit from a clear step-wise approach to screening for a deep vein thrombosis (DVT). In this video, Elizabeth Tenny, from the Stanford Vascular Lab, focuses on femoral vein imaging and explains where to start the study, what techniques to use, and how to approach anatomical variations.
Assessing transcatheter aortic valve replacement (TAVR) using echocardiography
Echocardiography plays a big role for imaging in patients who are about to undergo a transcatheter aortic valve replacement (TAVR). What should you pay attention to while assessing if a TAVR is indicated instead of surgical replacement? What examination should you order for valve sizing? What needs to be done after the procedure? Find out in this lesson presented by Samir Sulemane, a Senior Clinical Scientist and echocardiography expert at Royal Brompton and Harefield NHS Trust, UK.
Diagnosing prosthetic valve endocarditis with echocardiography
Prosthetic valve endocarditis (PVE) is a microbial infection of the valve. How do you diagnose PVE with ultrasound? Why do you need to differentiate between early and late PVE? When do patients need surgical treatment? Find out in this lesson presented by Samir Sulemane, a Senior Clinical Scientist and echocardiography expert at Royal Brompton and Harefield NHS Trust, UK.
Assessing velocities and gradients of prosthetic valves using echo
Prosthetic valves often cause some degree of obstruction to the blood flow in comparison with native heart valves. How can we evaluate the valve obstruction with echo? What’s the role of Bernoulli’s equation? And what’s the cutoff value for the blood flow peak velocity? Find out in this lesson presented by Samir Sulemane, a Senior Clinical Scientist and Echocardiography Expert at Royal Brompton and Harefield NHS Trust, UK.
Echo pearls: introducing prosthetic heart valves
There are three main groups of prosthetic heart valves: mechanical valves, bioprosthetic valves, and homo- and autografts. Which prostheses are the most common? What are they made of and what are their main elements? Find out in this lesson presented by Samir Sulemane, a Senior Clinical Scientist and Echocardiography Expert at Royal Brompton and Harefield NHS Trust, UK.
Choosing the right hypertension medication for your patient
What is the most suitable antihypertensive agent for the general population? How does the recommendation change when the patient has diabetes or albuminuria? Would your drug of choice differ for Black patients? What antihypertensive drugs should you avoid in patients who want to get pregnant? In this video, Franz presents the answers based on the American College of Cardiology and American Heart Association (ACC / AHA) 2017 guidelines.
