CT anatomy
CT anatomy is read slice by slice, region by region. Practise naming the structures on real CT images across the body — the fastest way to make cross-sectional anatomy stick. Free, no account needed.

Single answer — type the structure
Correct — corpus callosum
How a CT is built
CT stacks thin axial slices you can reformat into coronal and sagittal planes. Density (Hounsfield units) and the window you choose decide what stands out — bone, soft tissue or lung.
Region by region
Head, chest, abdomen and pelvis each have their own landmarks, but the method is the same: find the great vessels and bones first, then place the organs around them.
The role of contrast
IV contrast highlights vessels and organ enhancement in phases; without it, bone and acute blood dominate. Knowing whether contrast was given helps you name structures.
Keep practising by region
Move through the rest of cross-sectional anatomy one region at a time — brain and abdominal CT, cardiac MRI and more — and let each explanation fix the structure in memory.
