High specifity of preoperative ultrasound in primary HPT

Objective: For preoperative localization of biochemically defined primary HPT high resolution ultrasonography (US) and technetium-99m sestamibi-scintigraphy (Tc-Mibi) is performed. Aim of this study was to evaluate the sensitivity and usefulness of US alone. Design: Between January 2004 and May 2007 we operated 77 patients with primary HPT. The diagnosis was determined by elevated serum-calcium and -PTH. To determine localisation preoperatively US was performed in 77 cases. Tc-Mibi was performed in 27 cases. All patients underwent bilateral cervical exploration. Results: US and Tc-Mibi were analysed and compared…
