Vet Imaging Lab

Learn veterinary imaging from first principles, then practise on real dog and cat images: identify every structure, quiz yourself, and decide what is normal and what is not.

Start here

Short lessons that explain how each modality works and how to read it, each ending on a real image.

Diagnostic Imaging

Learn to see, describe and interpret. Step-by-step radiography, CT and ultrasound paths on real images: find the finding, build the description, rank your differentials, then compare your interpretation with the expert report. Ultrasound includes video loops that need a connection.

Imaging Foundations

X-ray: how the image is made, positioning, film quality, Roentgen signs, thorax, heart size, lung patterns and the abdomen. CT, ultrasound and MRI from first principles. Then pattern recognition: one pattern per lesson on real confirmed images.

Spot the lesion

Real dog and cat cases from peer-reviewed, open-access case reports, every diagnosis confirmed by surgery, biopsy or necropsy. Name the marked lesion, work a full clinical case from the history, or find the lesion with the arrows removed. Plus a disease library across X-ray, ultrasound, CT and MRI.

Question bank

Original questions and "select every cause" differential drills across physics, thorax, abdomen, urogenital, musculoskeletal and neuro imaging. Each answer cites the printed textbook page; misses come back in spaced review.

Exam mode

A mixed, timed paper drawn from every lesson, confirmed case and radiologist-labelled radiograph. Marks at the end, weakest topics first, and missed questions go into your spaced review.

Call the findings

Real dog and cat chest radiographs from the VetXRay teaching set, each labelled by a veterinary radiologist. Tick what you see, from normal to cardiomegaly, effusion, pneumothorax or lung patterns, and compare with the radiologist.

CT cases

Each case opens in study mode: 3D model, three slice planes, and a structure list grouped by body system.

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.
Read. Judge every structure normal or abnormal, name the Roentgen signs that changed, then compare with the answer key. Misses and over-calls are scored separately.
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, location, number, margination and opacity (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.
