Lower extremity MRI: are their requests always appropriate in France?

Objectives: The primary aim is to assess current lower extremity MRI requests' relevance with a secondary focus on the knee.

Materials And Methods: Using data from the National Health Data System (SNDS), we conducted an observational study of adults (18+) who underwent lower extremity MRI between July 1 and December 31, 2021. This study included analyzing medical consultations and imaging procedures (particularly X-rays) in the 6 months before and after the index MRI, as well as medical procedures and hospitalizations related to knee procedures within 6 months post-MRI.
