Whilst whole body MRI is gaining momentum in cancer staging for multiple tumour types, relatively few groups have focused on the primary staging of prostate cancer.
In this study, we evaluated the role of an extensive multiparametric MRI protocol, including diffusion-weighted imaging in 23 patients against an 18F-choline PET-CT/ expert panel based reference standard.
According to the reference standard, we found that whole body MRI provided an equivalently high diagnostic accuracy vs. PET-CT in lymph nodes, and outperformed PET-CT in the detection of bone lesions. However, higher technical error rates suggest MRI reporting experience needs to be developed first.
