The sensitivity, specificity, and accuracy of PET/CT tended to be superior to those of CT, but these values were not significantly different (95%, 91%, and 93% versus 82%, 85%, and 84%; P = . 25, . 50, and . 063, respectively). The clinicians changed their assessments of disease extent and management plans in 18 (32%) and 11 (20%) patients, respectively, based on the PET/CT results [123]. FDG-PET/MRI Skull Base to Mid-Thigh There is no relevant literature to support the use of FDG-PET/MRI in the pretreatment staging of UTUC. MRI Abdomen and Pelvis Without and With IV Contrast Although there is limited literature to support the use of MRI Abdomen and Pelvis without and with IV contrast (separate from MRU) in the pretreatment staging of UTUC, it may be useful in some clinical situations. However, CTU and MRU are of greater usefulness because they allow for the comprehensive evaluation of the genitourinary tract, as well as the assessment of retroperitoneal and pelvic lymph nodes (see CTU and MRU sections). MRI Abdomen and Pelvis Without IV Contrast Although there is limited literature to support the use of MRI Abdomen and Pelvis without IV contrast (separate from MRU) in the pretreatment staging of UTUC, it may be useful in some clinical situations. However, CTU and MRU are of greater usefulness because they allow for the comprehensive evaluation of the genitourinary tract, as well as the assessment of retroperitoneal and pelvic lymph nodes (see CTU and MRU sections). MRI Abdomen Without and With IV Contrast There is limited literature to support the use of MRI Abdomen without and with IV contrast (separate from MRU) in the pretreatment staging of UTUC. Imaging of the entire abdomen and pelvis would be indicated for a comprehensive assessment of the entire urothelial system and evaluation for metastases.
