Ordering the right abdominal CT study for cancer staging
Some cancer types, such as pancreas adenocarcinoma or renal cell carcinoma, require a multiphasic CT study for staging. This video explains why it's important to review both the late arterial phase and the portal venous phase for some cancers.
Evaluating the abdominal arteries (aorta) with the help of CT
How does a radiologist make sure they don't miss anything when reviewing the aorta and its branches on an abdominal CT? In this video, an abdominal CT expert shows his search pattern.
Diagnosing hepatocellular carcinoma with CT
Hepatocellular carcinoma (HCC) is a unique type of cancer in that it can often be diagnosed based on imaging features alone. In this video, you'll learn how to recognize this cancer right away on a multiphasic CT exam.
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.
Venous ultrasound course: interpreting DVT compressibility and chronicity on ultrasound
Deep vein thrombosis (DVT) is a common clinical problem, affecting around 500 000 Americans yearly, according to the CDC. Diagnosing a DVT can be simple, if we master the most important technique of DVT ultrasound–checking for compressibility. In this video, our expert Elizabeth Tenny, from the Stanford Vascular Lab, explains how to diagnose a dangerous clot and what a venous ultrasound beginner can mistake for a DVT.
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.
