Four-Dimensional Computed Tomography: Clinical Impact for Patients with Primary Hyperparathyroidism

Abstract

Background: In recent years, four-dimensional computed tomography (4DCT) has emerged as a new localization study for primary hyperparathyroidism (pHPT). Objective: We aimed to assess the added value of 4DCT in our institution in the first 4 years of use. Methods: A retrospective cohort study was conducted from February 2004 to June 2015. Since 2011, patients over 50 years of age without concordant sestamibi-SPECT (SeS) and ultrasound (US) findings underwent 4DCT. Imaging results, surgical findings, histopathology, and postoperative biochemistry were collected. Results: A total of 536 parathyroid operations in 510 patients were performed during the study period. The overall cure rate was 99.2..
