CT guided percutaneous fine needle aspiration of intra-abdominal and pelvic masses

This paper describes a technique for performing CT guided fine needle aspiration of abdominal and pelvic lesions and presents the results of aspirations carried out in 21 patients with suspected or known malignant disease. In 1977 criteria were reported for the use of CT compared with ultrasound in the investigation of the pancreas and these apply generally to its application as guiding tool in fine needle aspiration biopsy (FNAB).
