IR work concentrating in fewer hands: share of radiologists doing any IR dropped from 70% to 50% over 15 years

The proportion of radiologists performing any IR-related work fell from 70% in 2008 to 50% by 2023, per new JVIR research — suggesting IR is consolidating into a smaller, more specialized subset of the workforce.

• A 20 percentage-point decline over 15 years implies a structural shift toward subspecialty-trained IR practitioners and away from general radiologists performing occasional IR procedures.
• Key limitation: design details, data source (claims vs. survey), and whether part-time or retired radiologists were included are not specified in the available snippet, limiting interpretability.
