CT Atlas: Sectional Anatomy

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

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
• Search any structure and 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 mode asks you to name the highlighted region or to find a structure on the slice, and scores you.
