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.
