Professional Relative Value Units (RVUs) quantifying productivity of radiologists in the United States were used to study trends from 1973 to 1989 in the distribution of productivity among the various imaging techniques. Data from a 1989 survey were used to estimate the distribution of radiology examinations among techniques for 1989. A difficulty index (RVUs per examination) was calculated for each technique weighted by actual CPT-code occurrences reported in that survey. ⋯ The percentage of procedures and RVUs represented by vascular/interventional has remained relatively constant. The overall difficulty index has risen by 18% from 1973 to 1989. These trends should influence the allocation of space, equipment, and human resources in radiology department planning and management.
