Learn radiology anatomy & clinical reasoning using x-ray, CT, MRI and ultrasound. This app is designed for medical trainees and medical professionals to increase their confidence in identifying normal anatomic structures, ordering the most appropriate imaging test and identifying common pathology.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be.

Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
