Same day comparison of PET/CT and PET/MR in patients with cardiac sarcoidosis.

ABSTRACT:

Background

Inflammatory cardiac disorders, in particular, sarcoidosis, play an important role in left ventricular dysfunction, conduction abnormalities, and arrhythmias. In this study, we compared the imaging characteristics and diagnostic information obtained when patients were imaged sequentially with PET/CT and then with hybrid PET/MRI on the same day following a single ¹⁸F-FDG injection.

Methods

Ten patients with known or suspected sarcoidosis underwent imaging in sequence of (a) ^99mTc-MIBI, (b) ¹⁸F-FDG with PET/CT, and (c) ¹⁸F-FDG with 3T PET/MRI. Images were compared quantitatively by determination of SUV_max and SUV on a voxel by voxel basis, and qualitatively by two experienced observers.
