Ultrasonography detection of parathyroid lesions in patients with hyperparathyroidism / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the usefulness of ultrasonography in detecting parathyroid lesions in the patients with hyperparathyroidism. Methods The results of ultrasonography were compared with operative and histologic findings, and other imaging techniques such as 99m-Tc-sestamibi scintigraphy and CT in 210 patients with proved hyperparathyroidism.Results The overall sensitivity and specificity of ultrasonography in detecting parathyroid lesions were 68.62%, 93.79%. Lesions at lower pole of thyroid were more likely to be detected than ectopic ones. Ultrasonography was helpful in diagnosis of parathyroid adenoma, hyperplasia or carcinoma when combined with clinical manifestations. Conclusions Ultrasonography is a useful means in preoperative localizing of hyperparathyroidism.
