Abstract
The preoperative diagnosis of localization and number of pathological parathyroid glands in very important for surgions. In this paper we describe the diagnostic results of MRI comparing to those of CT, Ultrasonogram and T1-Tc subtraction scintigram.
The materials were 65 parathyroid glands of 19 cases (3 cases of parathyroid adenoma and 16 cases of hyperplasia following chronic renal failure) operated on at the department from May 1989 to December 1990.
Diagnostic sensitivity rate of MRI, CT, T1-Tc and Ultrasonogram were 43.1 (%), 50.8, 52.3 and 55.4, respectively. On the otherhand false negative rates were 0 (%), 2.9, 5.56 and 18.2, respectively. It is concluded that, MRI can not provide excellent results for localizing diagnosis of the pathological parathyroid and general diagnosis based on various imaging methods is recommended.
