Abdominal fine needle aspiration biopsies with CT and ultrasound guidance: techniques, results and clinical implications.

Experience with fine needle aspiration biopsy (FNAB) of solid intraabdominal masses with computed tomography and ultrasound guidance in 117 patients at a large community hospital is described. An overall accuracy of 86%, sensitivity of 86%, and specificity of 93% was obtained. FNAB was found to be safe and accurate and obviated the need for surgery in nearly 50% of patients. Further experience is required to assess the value of FNAB in solid renal masses and in abdominal lymphoma.
