The ‘ring of fire’ Foley balloon
Previously, we talked about the utility of ‘twinkling sign or artifact’ in detection of kidney stones. Interestingly, balloon of the Foley catheter can also twinkle on color Doppler appearing like […]
Pitfalls of inferior vena cava M-mode
Visual assessment of IVC collapse using B-mode (grayscale imaging) is generally favored over M-mode, although in theory, M-mode can provide an accurate measurement of the collapsibility index. There are several […]
An intriguing tale of B-lines in a dialysis patient
Dr. X is rounding on an ESRD patient who initially presented with dyspnea after missing a dialysis (HD) session; underwent dialysis in the hospital. Pt asymptomatic at the time of […]
Sonographic appearance of an ureteral stent
Here is the image of right kidney obtained from a patient with history of obstructive uropathy. Note the hyperechoic double-lined structure in the collecting system area: that’s ureteral stent. Here […]
Execution of the NephroPOCUS curriculum
A POCUS program runs most effectively when there are at least two (to three) core faculty members who can consistently devote meaningful time to its development. Depending on the size […]
IVC collapse: fact or artifact?
In clinical practice, size, and collapsibility of the IVC is used as a surrogate for right atrial pressure (RAP). In spontaneously breathing patients, inspiration causes negative intrathoracic pressure and collapses […]
What is LV foreshortening?
This is a commonly heard term in echocardiography. Foreshortening occurs when the ultrasound beam does not cut through the true apex of the left ventricle but transects above and anterior […]
