“…107 Applying the NI-RADS criteria 16 to PET/MR imaging in a retrospective study including 46 patients, Patel and colleagues reported that PET/MR imaging scores showed a strong association with treatment failure for the primary site, neck lymph nodes, and combined sites, and the AUCs of PET/MR imaging scores versus treatment failure were 0.864 to 0.987, P < .001. 108 The investigators, therefore, concluded that PET/MR imaging has an excellent discriminatory performance for treatment outcomes of HNSCC when NI-RADS is applied.…”
