Figure 3: PET/MRI TNM staging: in a 56 year male of carcinoma of prostate: PET MIP (a) shows PSMA avid prostate lesion with nodal metastasis. Regional PET/MRI with multiparametric MRI (mpMRI) shows a PIRADS 4 lesion in bilateral peripheral gland appearing hypointense in axial T2 (b) with diffusion restriction (c), hypointense in ADC map (d), enhancing in post contrast VIBE (e) with increased Choline in MRS (f). Spatially correlative coronal T2 (h) and fused PSMA PET/MRI images (h) show organ confined PSMA avid prostatic lesion and chain of iliac and retroperitoneal nodes. Note: Multiparametric assessment of a marrow lesion in right ilium using the protocol; axial STIR, T1 TFL, post contrast VIBE image (i-k) with no PSMA uptake in PET/MRI Fused image (l) and showing no diffusion restriction in Axial DWI and ADC map (m & n): non metastatic
