High-resolution Ultrasound in Combination with Colour-Doppler Sonography for Preoperative Localization of Parathyroid Adenomas in Patients with Primary Hyperparathyroidism

Abstract

High-resolution ultrasonography by experienced examiners is a highly sensitive procedure for the preoperative diagnosis of parathyroid adenomas in patients with primary hyperparathyroidism. With this method, a unilateral neck exploration is sufficient in about 90 % of the patients. Additionally, detection of feeding vessels by colour-Doppler sonography is an important indication of a parathyroid lesion. Nonetheless, the experienced surgeon remains the standard of reference.
