[Image diagnosis of hyperparathyroidism].
Between January, 1983 and January 1988, the diagnosis of hyperparathyroidism was made on 14 patients (8 primary and 6 secondary), and was identified operatively in all. The procedures for image diagnosis were computed tomography (CT), ultrasonography and scintigraphy. Scintigraphy was performed using Tc-99m and Tl-201 by a subtraction technique. For primary hyperparathyroidism, the accuracy of localization was 100% by CT, 87.5% by ultrasonography, 100% by scintigraphy, and 100% by the combination of these three methods. For secondary hyperparathyroidism, it was 68% by CT, 68% by ultrasonography, 36% by scintigraphy and 84% by the combination of these three methods. Ultrasonography and CT were quite useful for imaging of small abnormal parathyroid glands. The accuracy of scintigraphy in secondary hyperparathyroidism was low. Because the swellings of glands do not occur equally in most secondary hyperparathyroidism cases, we consider that large glands absorb the majority of injected radionuclides. Some discussion on merits and demerits of each image procedure was done.
