ABSTRACT

Objective To evaluate the safety and accuracy of CT-guided cutting needle biopsy for the hepatic lesions near diaphragmatic dome.Methods A total of 25 cases with hepatic lesions near the diaphragmatic dome were undertaken CT-guided cutting needle biopsy using 16 gauge or 18 gauge core biopsy needles.Results Histological examination showed malignancy in 17 cases and benign in 8 with 2 false negative results(8%),and there were no false positive results.The specificities of malignant and benign lesions were 100% and 75%,respectively.Overall accuracy was 92%.Pneumothorax,needle tract hemorrhage,and subcapsular hepatic hemorrhage occurred in 2(8%),1(4%)and 1(4%),respectively.Conclusion CT-guided cutting needle biopsy for the hepatic lesions near diaphragmatic dome is a reliable and relatively safe diagnostic method.(J Intervent Radiol,2007,16838-840)
