CT-guided needle biopsy of the pancreas: a retrospective analysis of diagnostic accuracy.

The purpose of this study was to evaluate the accuracy of percutaneous needle biopsy of the pancreas and to compare its sensitivity with that of simple computerized tomographic (CT) prediction of malignancy. The records of 41 patients who underwent CT-guided percutaneous needle biopsies of the pancreas during a 4-yr period were reviewed retrospectively. Pre-biopsy CT scans were evaluated independently by two experienced radiologists in a blinded fashion.
