Learning objectives: To demonstrate the superior diagnostic accuracy of [18F]FDG-PET/MRI over PET/CT for detection of liver metastases.

Background: PET/MRI is a new technique, with greater sensitivity and specificity in comparison to PET/CT in localization of liver metastases. The fusion of PET and MRI data showed encouraging results.  A comparison of the diagnostic accuracy of PET/MRI compared with PET/CT in the detection of abdominal me[...]

Findings and procedure details: We evaluated the case of a male patient, from 48 years of age, with a history of rectal cancer, operated and treated with RT and QT. It was suspected at the time of the study the presence of Hepatic metastases in the patient. Was performed 18F-FDG PET/CT whole body at 60 min[...]

Conclusion: MRI sequences in conjunction with PET imaging have been shown to be an effective tool in the exploration of patients with suspected hepatic metastases. Therefore, it is considered a study of greater sensitivity and specificity in relation to PET/CT. It is necessary to increase the number of patients[...]
