Rationale and Objectives: To determine trends in nonvascular image-guided procedures at an urban general hospital over a 10-year period and to compare utilization of nonvascular interventional radiology (IR) over the decade 2001-2010 to a previously reported analysis for 1991-2000. Methods: With institutional review board approval, a 20-year quality assurance database verified against the radiology information system was queried for procedure location (eg, pleura, liver, bowel, and abdomen) and type (eg, biopsy, catheter insertion, and transient drainage), demographics, and change over time. Yearly admissions and new hospital numbers assigned each year served to normalize for overall hospital activity. Results: A total of 50,195 IR procedures were performed in 24,309 distinct patients (male:female, 12,625:11,684; average age, 60 years), 940 procedures performed in age
