The Influence of MR Contrast for PET Qualification in Pituitary Tumor with Simultaneous Integrated PET/MR

Conclusions: The feasibility of application of the GBCA on integrated simultaneous PET/MR was notarized and validated on account that the uptake ratio before and after the GBCA injection has not significant changes (P>0.05).

MR and PET/MR images from a representative patient. Coronal T1 image (A) and enhanced T1 imgae(B), sagital T1 FS image (C) and enhanced T1 FS image (D), T2 propeller image (E), T2 FS Propeller image (F) are shown in the figure. Fused PET/MR (MAC-T1) and Fused enhanced PET/MR (MAC+-T1) are displayed in (G) and (H). The lesion is more clear in the enhanced MR image compared with traditional MR image. In other words, the lesion is not that clear in T1, T2,or e...
