CT Atlas: Radiology Anatomy

CT Atlas teaches radiology anatomy on real CT scans. Learn cross-sectional anatomy slice by slice in the axial, coronal and sagittal planes, tap any region to see its name, and quiz yourself until you can read a CT scan on your own.

A CT scan anatomy atlas for medical students, radiology residents and CT technologists: 150 to 219 labelled structures per scan, the vertebral level of every axial slice, and where each structure usually lies, measured on 1,119 real scans.

WHAT YOU GET
• Real CT scans, not drawings: men and women, a child, a CT angiography and a whole-body scan from head to pelvis
• 150 to 219 labelled structures per scan: organs, bones, vessels, muscles, liver segments, heart chambers, brain and neck
• Axial, coronal and sagittal views that stay on the point you tapped
• The vertebral level of every axial slice
• Names in English and Latin (Terminologia Anatomica), plus Spanish, Portuguese, French, German, Russian and Vietnamese
• Soft-tissue, lung and bone windows
• Pinch to zoom, and search any structure to jump to the slice where it is largest

LEARN WHERE THINGS USUALLY ARE
For each structure, see the vertebral levels it usually lies at and its typical volume for the patient's age and sex, measured on 1,119 real scans. The pancreas, for example, usually lies at T12–L2.

TEST YOURSELF
Quiz yourself by topic: organs, bones, muscles, heart and vessels, or vertebral levels. Name the highlighted region, find a structure on the slice, or say which vertebral level an axial slice is at. Your score for each topic is kept, and the structures you miss come back first.
