📚 Happy World Book Day.
We may be biased — but this is the one we'd put on every sonographer's shelf right now.
The Art of Vascular Ultrasound by Jean White-Melendez and William Schroedter — the same instructors who teach ESP's vascular registry review course. Highly visual, organized by exam, and written by people who actually do this work. Whether you're prepping for your first registry exam or you've been scanning vascular for years, this one stays relevant.
The kind of book you buy once and never get rid of.
And while we're at it — if you don't already own Understanding Ultrasound Physics by Dr. Sidney Edelman, today's a good day to fix that. The go-to resource for physics in diagnostic medical sonography. Period.

"Turn the lights off when you leave."
Sonographers: What if… we just never turn them on? 😄
Happy Earth Day. 🌍

We won't pretend scanning in the dark is our contribution to the planet — but here's one small thing that actually is:
Recycle your gel bottles.
Most ultrasound gel bottles are #2 or #4 HDPE plastic — both widely recyclable. A quick rinse with warm water, a few seconds upside down to drain, and they're ready for the recycling bin instead of the trash.
Gel is water-soluble and non-toxic, so rinsing is sink-safe. No special disposal needed.
It's not a grand gesture. But multiply one bottle per room per day across every ultrasound department in the country and it adds up.

Seashore or barcode? Your M-mode answer to one of the most important yes-or-no questions in lung ultrasound.

If you see a granular “sandy” pattern below the pleural line, that’s the seashore sign – lung sliding is present, and pneumothorax is unlikely.

If everything turns into parallel horizontal lines, that’s the barcode (stratosphere) sign – no sliding, and now pneumothorax moves way up your differential.

How to check it right:
Use a linear probe (curvilinear or phased are just fine during an eFAST scan) for the best pleural detail. Place it in the anterior chest (2nd–4th intercostal space, midclavicular line) with the probe between the ribs. Find the pleural line, then drop into M-mode.

Reality check:
Barcode sign ≠ automatic pneumothorax. No sliding can also be seen with apnea, mainstem intubation, fibrosis, or pleurodesis.

Continuing education can feel like just another requirement, but it plays a much bigger role in how you grow as a sonographer.

CMEs help you stay current as technology and protocols evolve, so you’re not relying on what you learned years ago. They reinforce concepts you may not use every day and sharpen your clinical judgment when something doesn’t look quite right.

They also build confidence. The more you understand the “why” behind what you’re seeing, the more intentional your scanning becomes and that shows in both image quality and patient care.

And yes, they keep your credentials active. But more importantly, they keep you progressing instead of plateauing.

This doesn’t happen by chance.

Passing your exam isn’t about luck or last-minute cramming. It’s built in the hours you put in now, the concepts you take time to understand, and the consistency you show up with every day.

If it were easy, everyone would do it.
But you’re doing the work and that’s what sets you apart.

Stay with it. It will pay off.

🐇Bunny sign: Vertebral artery Doppler waveform with two antegrade peaks separated by a mid-systolic dip, resembling rabbit ears.

🥷Why it happens: Proximal subclavian stenosis causes a brief mid-systolic flow reversal as blood is pulled toward the arm, then returns to antegrade flow.

💪Clinical significance: A pre-steal/partial steal pattern – suggests evolving subclavian steal. Patients may be asymptomatic or develop symptoms with arm use.

🎭Scanning tip: If suspected, use arm cuff occlusion and release to provoke and unmask the waveform.

🕶️Differentiate from artifact: Reproducible notch in systole over multiple cardiac cycles + ipsilateral arm BP difference (>20 mmHg).
