1,900+ must-know interactive cases, carefully curated by radiologists and tailored to your level of training.
Learning radiology can be intimidating... but it doesn't have to be.
Meet CaseStacks.
Over 2,100 interactive radiology cases, curated by radiologists for your level of training. Scroll, window, and view cases full screen โ just like on PACS. Click linked findings in each writeup to jump straight to them on the image. Cases include sample reports, a focused discussion section, original illustrations, and videos.
Our site includes 3 main courses: Call Preparation, Introduction to Radiology, and Neuro Fellowship.
Call Preparation โ our comprehensive curriculum for junior residents preparing for call covering both classic and atypical presentations. Use the call simulator to practice a real call shift โ shuffle cases, enter your own preliminary report, and receive constructive AI feedback.
Intro to Radiology โ a course coming later this year designed specifically for beginners. Terms are defined inline, lessons include introductory videos, and cases include guided video reviews by a radiologist who steps you through every finding. Lessons also include high-yield multiple choice questions that reinforce what you've learned and prepare you for boards.
Neuro Fellowship โ a course tailored for fellows and practicing radiologists with in-depth reviews of advanced neuro topics like brain tumors, featuring rare diagnoses, differentials, and clinical pearls.
Have a question on any case? Simply ask Voxel, our AI radiology tutor, tailored to your level of training and aware of the case you're studying.
The entire platform is packed with features like dark mode, text-to-speech, in-depth progress tracking, and the ability to earn CME credits and certificates.
Every lesson includes free cases. Upgrade to PRO to unlock the full library.
Comprehensive radiology education from basics to advanced subspecialties

"If CaseStacks existed when I was an R1 or R2, I absolutely would have paid for the service...before starting call. It would've been invaluable for my confidence going into a challenging experience."
Ben White, MD
Associate Program Director at Baylor University
"[CaseStacks] is an outstanding educational resource providing active, practical preparation for residents getting ready to take call."
Carol Geer, MD
NeuroRadiologist, Wake Forest
"The ability to change sequences, actively window, and really drive helps material stick in a way that reading a book simply does not."
Joe Wilson, MD
Assistant Professor, U Chicago
"For R1s: radiology residency is a volume game. The best resource I found for R1 rotations and call prep was @CaseStacks."
Vedant Acharya, MD
IR/DR PGY-3, UPenn
"One of the best ways for #RadRes to learn radiology is by seeing and interacting with as many cases as possible."
Paul M. Bunch, MD
Neuroradiologist, Wake Forest
"I asked my resident how he knew so much radiology already and he told me it's because of you!"
Maria Velasco, MD
Cardiothoracic Radiologist, USF
"@CaseStacks was one of the most helpful resources late-R1/prior to taking call."
Ali Tejani, MD
Neuroradiology Fellow, UCSF
"True engagement cannot just be sit behind the resident and let the student ask a question every 10 minutes. Need to show and teach students through real cases through a modality such as @CaseStacks"
Adam Petraglia, MD
Radiology Resident, Wake Forest
"Did a demo of this product and it was phenomenal! Clean interface, self-directed and quiz features. Great learning tool and assessment."
Courtney Tomblinson, MD
Neuroradiologist & Fellowship Director, Vanderbilt
"I'm a huge fan of CaseStacks, especially for call prep!"
Xiao Wu, MD
IR/DR Resident, UCSF
"The first and second year residents in particular have been enjoying @CaseStacks. It seems to convey the fundamentals with walkthroughs of classic cases."
Alexander Rand, MD
Breast imaging and general radiologist
"My favorite learning resource in radiology residency has been @CaseStacks with their unparalleled neuro case collection."
Sagar Wagle, MD
Musculoskeletal radiology fellow, Stanford
"+1 for casestacks. Whenever I return to overnight call I go through as many cases beforehand (and all the neurocases) just to brush up. It's a quality product, and an excellent use of your education fund as a resident."
