Four-dimensional computed tomography for parathyroid localization: a new imaging modality.

摘要: Introduction Four-dimensional computed tomography (4DCT) is a new parathyroid localization technique not previously reported in Australia. It provides both functional and anatomical imaging single test, with superior sensitivity compared sestamibi scintigraphy (SeS). This study examines the utility of 4DCT defined clinical situations. Methods This retrospective cohort tertiary referral hospital setting. One hundred consecutive operative cases primary hyperparathyroidism (99 patients) undergoing preoperative SeS. Localization studies were correlated findings, histopathology outcomes. The was analysed three common settings: positive SeS (Group A, n = 68), negative B, 21) re-operative C, 11). Results The overall 92% 70% for to Groups B C (76% versus 0% 91% 46%, respectively). cure rate 98%, 94% completed as minimally invasive procedures. Up 62% Group potentially avoided bilateral neck exploration owing 4DCT. Conclusions 4DCT an accurate providing abnormal glands. However, advantage speed simplicity image acquisition needs be balanced against small risk increased radiation exposure younger patient group.
