T1 Ce-MRI, fused ¹⁸F-FACBC/ce-MRI, and fused ¹⁸F-FDG/ce-MRI are shown from left to right. The left and right panel show baseline and response PET/MRI images, respectively. Patients 1–3 (P1–3) are distributed vertically. Scale for ce-MRI was 0–600. Scale for PET detected lesions was SUV_background − SUV_max. Scale for PET undetected lesions was SUV_background—SUV_max (baseline lesion uptake). For P3 ¹⁸F-FDG scans, the lesion was undetected in both scans and the scale used was SUV_{background (mean)} − SUV_{background (max)}
