Four-dimensional computed tomography and ultrasonography for prediction of pathological parathyroid location: a retrospective review of a single surgeon's patients at a single institution.

Background: Pre-operative imaging is a well-established practice for managing hyperparathyroidism with the plan for excision; however, there is a paucity of information regarding the success rate of concordant imaging studies. Our goal was to compare the accuracy (sensitivity) of four-dimensional computed tomography (4DCT) and ultrasound (US) when predicting the side and quadrant of parathyroid lesions, confirmed with surgical location (from a single surgeon).

Methods: A retrospective review of 437 patients from a single surgeon undergoing parathyroidectomy from December 2013 to January 2020 at an academic medical center was performed.

The Utility of the Cl:PO4 Ratio in Patients With Variant Versions of Primary Hyperparathyroidism.

Objective: To determine the significance and impact of additional chloride testing as part of a diagnostic laboratory test battery for borderline primary hyperparathyroidism (pHPT).

Study Design: Retrospective database review of parathyroidectomy patients.

Setting: A tertiary care, academic health sciences center.
