18F-FDG PET/CT and PET/MRI Perform Equally Well in Cancer: Evidence from Studies on More Than 2,300 Patients

摘要: (18)F-FDG PET/CT has become the reference standard in oncologic imaging against which performance of other modalities is measured. The promise PET/MRI includes multiparametric to further improve diagnosis and phenotyping cancer. Rather than focusing on these capabilities, many investigators have examined whether PET combined with mostly anatomic MRI improves cancer staging restaging. After a description scanner designs discussion technical operational issues, we review available literature determine assessments are improved PET/MRI. data show that feasible performs as well most types Diagnostic advantages may be achievable prostate bone metastases, whereas disadvantages exist lung nodule assessments. We conclude provide comparable diagnostic information when used simply framework. Thus, could lieu if this approach becomes economically viable reasonable workflows can established. Future studies should explore potential MRI.
