Imaging guided percutaneous hepatic biopsy: diagnostic accuracy and safety.


During the 3-year period from May 1981 to June 1984, 145 patients with hepatic abnormalities demonstrated by computed tomography (CT) or ultrasonography (US) underwent 151 imaging guided percutaneous hepatic biopsies. These biopsies were performed with needles ranging in size from 21-gauge aspiration to 14-gauge cutting type. Histologic and cytologic results were correlated with subsequent surgical, autopsy, and clinical follow-ups ranging from 2 months to 3 years. The overall accuracy for imaging-guided biopsies was 92.1% and 98% for diagnosis of malignant lesions. Our complication rate of 1.3% is comparable to that reported in other studies. We discuss indications, techniques, and risks for imaging-guided percutaneous hepatic biopsy.
