Any imaging study explained end to end: how the modality physically works, when to order it, contrast and prep decisions, what findings mean, and the next step after the read.

Imaging questions are where students get caught twice: first on rounds, when asked why this patient needs a CT with contrast rather than without, and again on the shelf, where "most appropriate next imaging study" is a fixture. The Imaging Explainer teaches the reasoning behind both.
Ask about any study, from CT chest with contrast to a V/Q scan, an echocardiogram, or MRI brain without contrast, and it explains how the modality actually works, what it shows well and what it misses, when it is the right first study, and the contrast, prep, and safety considerations like renal function, pregnancy, and pacemakers.
Then it goes to the findings: what the classic patterns look like, what they mean clinically, and what each read should trigger next. The physics stays practical, just enough to explain why the image looks the way it does and why one modality beats another for the question being asked.
Any modality: x-ray, CT with or without contrast, MRI, ultrasound, echo, V/Q, nuclear studies.
What the study shows, when it is the right choice, and the contrast, prep, and safety decisions attendings ask about.
Classic patterns, what each means clinically, and what the result should trigger next.
Yes, in depth: what contrast adds for each study, when it is required versus harmful, and the renal, allergy, and timing considerations that come with it.
Yes. Modality selection, sensitivity trade-offs, and next-step logic are exactly what shelf and Step 2 imaging questions test.
Only as much as helps: enough of how each modality works to explain why findings look the way they do and why one study answers a question another cannot.
