Purpose
Preoperative localisation of parathyroid adenomas (PAs) is critical to successful minimally invasive parathyroidectomy.
Ultrasound and sestamibi scintigraphy remain the primary imaging modalities but four dimensional CT (4DCT) has gained popularity, often after alternative modalities have failed.
Surgical approach for parathyroid gland resection has changed from bilateral neck exploration to minimally invasive parathyroidectomy with shorter operating times and reduced complications. Recently, 4DCT is being used for difficult cases when the gland has not been demonstrated by sestamibi or ultrasound. The fourth dimension of 4D CT is time, enabling assessment of changes in Houndsfield Units at different intervals following contrast administration.
This project aims to evaluate the usefullness of 4D CT in diagnosing PAs relative to other modalities in our practice.
