Interventional Radiology Dictionary

Interventional Radiology uses a lot of complex and technical terms. Medical students or junior trainees can often find it difficult to understand a lot of the common terminology used in the day-to-day practice of IR. Here, we have listed some common terms that are used, with easy to read explanations of what they are.

 

Written by Dr Nick Lorch, Radiology Trainee in Leeds.

Stentreiver

A stent which can unfold and then be refolded into a catheter. These are used to grab blood clots and pull them back into a tube.
