"I read the Call Guide the night before my first overnight. I actually felt prepared. Found a tension pneumo that I might have second-guessed without the checklist pattern locked in."

Why This Matters
On call, there's no time to think.
There's only what you already know.
Missed findings follow you home
One unread hemorrhage. One missed PE. The clinical and psychological cost is real — and it compounds with every shift.
No framework at 3am
Textbooks teach anatomy. Call demands decisions. Most residents go in with knowledge — but no system for what to do with it.
Decision fatigue is real
Studying 12 resources means remembering none at 3am. You need one trusted source, built for call — not a library.
The Call Guide
Everything you need to not miss

Your first overnight call shouldn't be a guessing game. The Call Guide gives you a radiologist-built system — the checklists, frameworks, and pattern recognition that take years to develop, distilled into one essential reference.

What residents are saying
★★★★★
"The newsletter is the one email I actually open every week. Joshua teaches the way attendings think — not the way textbooks write."
★★★★★
"Eighteen dollars. I spend more than that on coffee before a 28-hour call. This is the best money I've spent on my radiology education."

Radiology Roadmap is built for medical students preparing for radiology rotations, MS-3s and MS-4s applying to radiology, and radiology residents in their early years who want to build real diagnostic confidence — not just memorize lists. If you want to understand how attendings actually think, you're in the right place.
The Call Guide is a focused PDF reference built for on-call use. It includes critical findings checklists organized by body part (head, chest, abdomen/pelvis), decision frameworks for the most common emergent diagnoses, pattern recognition cues for can't-miss findings, and a quick-reference format designed for fast reads between studies. No fluff. Every page earns its place.
Yes. The Roadmap newsletter is completely free. Every Sunday, you get one high-yield radiology lesson — a sign, a pattern, a concept — that sticks. No upsell. No fluff. Just teaching. You can unsubscribe at any time, no questions asked.
Once a week. Every Sunday morning, you'll get one Roadmap issue in your inbox. Occasionally I'll send a short note about a new resource or a topic I feel is urgent, but I respect your inbox. You will never get daily emails or promotional spam.
