CT Anatomy Lab

Real dog and cat CT scans with every segmented structure named. Hover anywhere to identify what you are looking at, then quiz yourself until you can find it without help.

How to use it

Explore. Move the pointer over the 3D model or any slice and the structure underneath is named, in English and Latin, with its body system. Click to select it: it lights up in every view and the card says what to look for.
Colour every structure. Tick the box to tint all segmented structures in the slices at once, then scroll the slice slider and watch how each one changes shape through the body.
Quiz. Ten questions per round. "Find" questions: click the named structure. "Name" questions: pick the highlighted one from four. Structures you miss come back more often, and your weakest ones show up in Explore.

A systematic read, every time

Students most often stop after the first abnormality or call normal anatomy abnormal. A fixed order fixes both.

  1. Tubes and lines firstEndotracheal tubes, catheters, implants. Identify them before anything else so they are not mistaken for anatomy.
  2. Skeleton, outside inSpine alignment, ribs, pelvis as a ring, long bones. Compare left with right.
  3. Organ by organSize, shape, margin, number, location, and density (the Roentgen signs), one organ at a time.
  4. Check the cornersEdges of the image, the start and end of the scan, areas behind the first finding.
  5. Compare with normalIs it truly abnormal, or a normal variant? Suture lines, growth plates and costal cartilage mineralisation fool everyone.
