To prospectively evaluate the diagnostic accuracy, procedural duration, and complication rates of CT-guided biopsies performed across diverse anatomical sites.
Prospective cohort analysis of 1,000 CT-guided biopsies performed in 955 patients over a 30-month period by 26 radiologists, with patient follow-up ranging from 3 months to 2 years.
Procedures targeted various locations, with 722 biopsies performed in the liver, retroperitoneum, pancreas, pelvis, and adrenal glands.
CT-guided biopsy yielded a sensitivity of 91.8%, a specificity of 98.9%, a positive predictive value of 99.7%, and a negative predictive value of 73.3%, based on 747 true-positive and 184 true-negative findings.
Diagnostic errors occurred in 69 procedures, consisting of 67 false negatives and two false positives.
Complications arose in 11 patients (1.1%), consisting of seven hematomas, three pneumothoraces, and one case of hematuria, resulting in no deaths and only one patient requiring surgical intervention.
