The Growing Size of Radiology Practices

Radiology practices grew in size throughout the 1990 to 2007 period. In general, changes were more rapid in 1990 to 2000 than since. The most conspicuous growth was in practices with 30 radiologists or more. This category almost quadrupled its share of radiologists. In contrast, the share of very small practices (1-4 radiologists) declined relatively little, by only approximately one-fourth.
