Relative value of three whole-body MR approaches for PET-MR, including gadofosveset-enhanced MR, in comparison to PET-CT. Clinical imaging Obara, P. n., Loening, A. n., Taviani, V. n., Iagaru, A. n., Hargreaves, B. A., Vasanawala, S. n. 2017; 48: 62–68


Evaluate MR protocol for PET-MR including coronal DWI (cDWI), fat-suppressed T2 (T2w), and gadofosveset-enhanced T1 (CE).18 patients underwent same-day PET-CT and PET-MR. Image quality and performance of each sequence, and combination of all three sequences, was evaluated with respect to PET-CT.Lesion conspicuity was best on cDWI, while delineation was best on CE. Considering all three sequences combined, both readers showed good sensitivity and specificity (>80%). Relative sensitivity was highest on CE and lowest on T2w.Whole-body MR performed well in detecting malignant lesions compared to PET-CT. CE showed overall highest performance.
