Diagnostic accuracy of 3T magnetic resonance imaging in the preoperative localisation of parathyroid adenomas: comparison with ultrasound and 99mTc-sestamibi scans

Objectives: To evaluate the diagnostic performance of 3TMRI in comparison with ultrasound (US) and 99mTc-sestamibi scan for presurgical localisation of parathyroid adenomas (PTAs) in patients with primary hyperparathyroidism (PHPT). Methods: Fifty-seven patients affected by PHPT were prospectively enrolled and underwent US, 99mTc-sestamibi and 3TMRI. T2-weighted and post-contrast T1-weighted Iterative decomposition of water and fat with Echo Asymmetry and Least squares estimation (IDEAL) sequences were acquired.

Dual-modality imaging with a ultrasound-gamma device for oncology

Recently, dual-modality systems have been developed, aimed to correlate anatomical and functional informa- tion, improving disease localization and helping oncological or surgical treatments.
Moreover, due to the growing interest in handheld detectors for preclinical trials or small animal imaging, in this work a new dual modality integrated device, based on a Ultrasounds probe and a small Field of View Single Photon Emission gamma camera, is proposed.
