positron emission tomography
E1161758
UNEXPLORED

How this entity was disambiguated
This entity first appeared as the object of triple T15521985 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.
