Matching Lesions and Uptakes with Index Tumours
The borders of the lesions in the mpMRI, the pathological uptakes in the68Ga-PSMA PET/MRI, and the index tumour of the specimen were drawn in transverse sections by the radiologist, nuclear medicine specialist, and uropathologist, respectively (Fig. 1). Each expert was blind to other image outside of their field. Diagnostic analysis was performed by dividing the prostate into four anatomic regions as left/right anterior and left/right posterior. A total of 256 anatomic regions were evaluated. The extension of the lesions in mpMRI and the pathological uptake in 68Ga-PSMA PET/MRI were matched separately for each region of the prostate with the extension of the index tumour into each region.
