Abstract
Diagnostic usefulness of such preoperative diagnostic techniques as xeroradiography, aspiration biopsy cytology, ultrasonography, and RI scintigraphy was evaluated in 454 patients with histopathologically established malignant thyroid tumore and 328 patients with similarly confirmed benign thyroid diseases who were seen at our department from 1980 through 1989. Results indicated that the probability of tumor malignancy ran higher in patients for whom xeroradiography, aspiration biopsy cytology, or ultrasonography results were positive. Adequate combination of these diagnostic tools seemed to result in a higher rate of correct diagnosis, although all fell sort of establishing diagnoses of tiny or follicular carcinomas.
