About the trial

What the trial wants to find out

Primary hyperparathyroidism is caused by overactive parathyroid glands, leading to elevated calcium levels in the blood. The standard preoperative imaging includes both a radiation-based imaging modality and conventional ultrasound. However, ultrasound alone is a faster, safer, and more patient-friendly alternative. This study evaluates an upfront ultrasound approach, where patients undergo ultrasound first, and only those with certain findings proceed directly to surgery without additional imaging. Patients with uncertain findings proceed to additional imaging. The study is designed as a prospective cohort with a non-inferiority analysis, aiming to confirm whether upfront ultrasound can achieve an acceptable diagnostic sensitivity. If successful, this approach could reduce patient burden, minimize radiation exposure, and optimize healthcare resources
