PURPOSE: The aim of this study was to investigate the clinical performance of whole-body F-FDG PET/Dixon-volume-interpolated breath-hold examination (Dixon-VIBE), T1-weighted, and T2-weighted MRI protocol in @entity1 with @entity14 . @entity1 AND METHODS: A total of 59 @entity1 with @entity14 were enrolled in this study. Each @entity1 had one of the following clinical conditions: initial stage before therapy, stage after neoadjuvant therapy, suspicious colorectal liver metastases, and colorectal liver metastases after chemotherapy. Fourteen @entity1 had primary @entity14 , whereas 38 @entity1 had a total of 132 @entity99 , 53 lesions existed before chemotherapy, and 79 lesions appeared after chemotherapy. The primary stage and metastases images were obtained using our PET/Dixon-VIBE/T1/T2 MRI protocol and were analyzed by 2 nuclear medicine physicians. Diagnostic accuracy was compared with contrast-enhanced MRI images, which were based on surgical pathology results. RESULTS: The sensitivity of our imaging protocol for primary @entity14 was 100% (14/14). T and N stage both showed 92.9% (13/14) accuracy. Of all 132 @entity99 , 115 metastatic lesions were analyzed, and 17 benign lesions were excluded (6 were during pretreatment cases, and 11 were during posttreatment cases). In pretreatment metastatic lesions (n = 47), the sensitivities of our protocol and dedicated MRI were 95.7% (45/47) and 100% (47/47), respectively. In posttreatment lesions (n = 68), sensitivities of our protocol and dedicated MRI were 75% (51/68) and 91.2% (62/68), respectively. CONCLUSIONS: Whole-body PET/Dixon-VIBE/T1/T2 MRI protocol is clinically useful for TNM staging and chemonaive hepatic metastasis in @entity14 .
