    Abstract:
    With the increased sophistication of radiologic imaging techniques, the sensitivity of detecting nonpalpable, deep-seated lesions has greatly improved. Coupling these techniques with fine needle aspiration biopsy (FNAB) provides a cost-effective, minimum-risk, highly sensitive and specific method of diagnostically evaluating the lesions. Over a four-year period (1985-1989) a total of 2,229 FNABs were performed at Loyola University Medical Center, Chicago; 539 of these biopsies were computed tomographically guided. The geographic computed tomographic biopsy sites were: thorax, 267 (49.54%); abdomen, 175 (32.47%); and retroperitoneum, 97 (18%). Four hundred eighty FNAB cases were diagnostic, with subsequent histologic follow-up in 284 (58%) cases. Fifty-nine (10.9%) FNABs were unsatisfactory; of them, 31 had subsequent diagnostic histology, and 9 remained unsatisfactory. A good correlation between FNAB and histology was observed, with an overall sensitivity of 93.2%, specificity of 98.8%, false-negative rate of 6.8% and false-positive rate of 1.2%. Diagnostic pitfalls and biopsy adequacy in computed tomographically guided FNABs are discussed.
