Happy Birthday Heinrich Hertz

Posted on February 22, 2012 by phil

Without Heinrich we would have no units for the frequency of our probes. We can thank him for these units as well as for proving Maxwell’s theory of electromagnetism, leading to the invention of radio and television. Â I suppose we should really be interested in thanking his grandnephew, Carl, who invented medical ultrasonography. Â Either […]

Left upper quadrant fluid

Posted on February 21, 2012 by sinaiem

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 free fluid to the unprepared. The first image shows a perisplenic (left upper quadrant) […]

Angles

Posted on February 16, 2012 by sinaiem

Finding the right angle is critical to optimal imaging. In fact ‘right angle’ or perpendicular imaging is the best way to get a clear image. At 90 degrees, many more sound beams reflect back to the transducer than at more shallow angles. In addition, the ultrasound energy is more spread out when it connects to […]

Cardiac tamponade

Posted on January 30, 2012 by sinaiem

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 distant heart sounds) isÂ pathognomonic for cardiac tamponade. You should also remember (to say to your colleagues who recite that tamponade is […]

Pupillary Light Reflex

Posted on January 28, 2012 by sinaiem

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 wondering why a pen light would not suffice for this physical examination standby, you have never encountered […]

Snell’s Law

Posted on January 27, 2012 by sinaiem

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 created with sound, it can be confusing that bone and air both create bright white signal as well […]

Case 5

Posted on October 25, 2011 by sinaiem

Here’s a quick case. Patient presents with urinary retention, Foley catheter placed, blood-tinged urine output. Initially the patient experiences great relief but gradually develops suprapubic discomfort again. Questions: What’s inside the bladder? What’s the bladder volume? How is that catheter working? What’s that bright echogenic arc coming of the superficial aspect of the Foley bulb?
