Arcuate vessels are commonly seen on ultrasound evaluation of the uterus. Occasionally they can be confused with subchorionic hemorrhage, ovaries, and other structures so it’s worth looking at their characteristic appearance. Once aga…
Rounding out our recent trifecta of biosafety posts is a description of cavitation. Cavitation is the formation of microbubbles in liquid which has been subjected to rapid pressure changes. This can happen from a variety of causes from beat…
Notes from Grand Rounds on Cardiac Arrest Ultrasound this morning. Screencast (in process) Handout RUSH in Arrest Algorithm  References: Atkinson, P R T, D J McAuley, R J Kendall, O Abeyakoon, C G Reid, J Connolly, and D Lewis. “Abd…
What does the MI on the sidebar of the ultrasound machine screen stand for? The Mechanical Index is a safety metric which lets the operator know how much energy is being transmitted into the patient during sonography. Remember that sound is…
What does the TI on the sidebar of the ultrasound display stand for? Thermal Index (TI) is a biosafety metric used to describe the potential of the ultrasound beam to raise temperature in the path of the beam. It is the ratio of the power u…
On April 18 the FDA released an alert regarding Other-Sonic Generic Ultrasound Transmission Gel, manufactured by Pharmaceutical Innovations Inc. The ultrasound gel was found to be contaminated with Pseudomonas aeruginosa and Klebsiella oxyt…
We are pleased to present our annual critical care ultrasound pre-conference course at the Clinical Decision Making in Emergency Medicine symposium in Ponte Vedra, Florida on Wednesday, June 20. Each year this intensive, hands on course fea…
Although we tend to suspect torsion only in cases where there is ovarian enlargement, cyst, etc., there are a number of studies that show these are not reliable (sensitive or specific) indicators of torsion. Radiology reports often seem to…
The Mount Sinai Department of Emergency Medicine hosted its annual ultrasound CME conference held on March 22 at the Stern Auditorium. Faculty, fellows and PAs from a number of institutions took part in our eighth annual conference. The c…
April 1, 2012: Researchers presented exciting new data on the use of extremely low-frequency ultrasound for the bedside diagnosis of a wide range of pathology. “We’re very excited by the technique,” remarked Bret Nelson as…
Many of our lectures reference the same pantheon of literature on ultrasound in the acutely hypotensive patient. For ease of reference here they are, with appropriate links to the original publications: UHP protocol Rose JS et al, Am J Em…
One common source of confusion or false positives in the FAST exam is the assessment of the left upper quadrant. We’ve already covered some tips on improving your view of the spleen. This post will illustrate how the stomach can mimic…
One of the major indications for bedside cardiac ultrasound is the detection of pericardial effusion and its extreme form, cardiac tamponade. You may remember that Beck’s Triad (hypotension, jugular venous distension, and muffled or d…
We’ve all seen ultrasound augment the physical examination and even allow for assessments we could not otherwise accomplish at the bedside. One great example is the use of ultrasound to check the pupillary light reflex. If you are won…
For some reason, most clinicians seem to grasp x-ray and CT scan imaging reasonably well. Denser structures are white, less dense are black, water dense structures are grey. Thus, when novice ultrasound users attempt to discern images creat…
