Diagnostic performance of PET/MRI and PET/CT to detect distant metastases and distant synchronous cancers. A The AUC for the per patient analysis (n = 82) was 0.947 [0.927–1] for PET/MRI and 0.975 [0.950–1] for PET/CT, respectively. There was no statistically significant difference between the two AUCs (p = 0.847). B The AUC for the per examination analysis (n = 103) was 0.965 [0.917–1] for PET/MRI and 0.968 [0.920–1] for PET/CT, respectively. There was no statistically significant difference between the two AUCs (p = 0.488). C The AUC for the per lesion analysis (n = 183) was 0.957 [0.928–0.987] for PET/MRI and 0.944 [0.910–0.979] for PET/CT, respectively. There was no statistically significant difference between the two AUCs (p = 0.574)
