The lesion map

Every lesion is a node, placed near the ones it radiographically resembles. Click one to read it and follow its threads to the look-alikes. Prefer a list? Browse the atlas. To rank a differential from findings, open the tool.

How to read the map
Node size: how common the lesion is (banded prevalence: rare → very common).
Similarity thread: a radiographic look-alike (region + origin-gated similarity). Click a node to reveal its threads. Very close, Close and Related compare a look-alike with how close ORAD's nearest look-alikes usually are; they are not probabilities.
Colour: the lesion's category. Open ▦ Categories to show/hide any group.
Selecting a node dims the rest of the map so its look-alikes stand out. To rank a differential from findings you enter, open the tool.
