abstract = {Multi-parametric magnetic resonance imaging (MP-MRI) is
currently the most comprehensive work up for non-invasive
primary tumor staging of prostate cancer (PCa).
Prostate-specific membrane antigen (PSMA)-Positron emission
tomography-computed tomography (PET/CT) is presented to be a
highly promising new technique for N- and M-staging in
recurrent PCa-patients. The actual investigation analyses
the potential of (68)Ga-PSMA11-PET/CT to assess the extent
of primary prostate cancer by intra-individual comparison to
MP-MRI.In a retrospective study, ten patients with primary
PCa underwent MP-MRI and PSMA-PET/CT for initial staging.
All tumors were proven histopathological by biopsy. Image
analysis was done in a quantitative (SUVmax) and qualitative
(blinded read) fashion based on PI-RADS. The PI-RADS schema
was then translated into a 3D-matrix and the euclidian
distance of this coordinate system was used to quantify the
extend of agreement.Both MP-MRI and PSMA-PET/CT presented a
good allocation of the PCa, which was also in concordance to
the tumor location validated in eight-segment resolution by
biopsy. An Isocontour of $50 \%$ SUVmax in PSMA-PET
resulted in visually concordant tumor extension in
comparison to MP-MRI (T2w and DWI). For $89.4 \%$ of
sections containing a tumor according to MP-MRI, the tumor
was also identified in total or near-total agreement
(euclidian distance ≤1) by PSMA-PET. Vice versa for
$96.8 \%$ of the sections identified as tumor bearing by
PSMA-PET the tumor was also found in total or near-total
agreement by MP-MRI.PSMA-PET/CT and MP-MRI correlated well
with regard to tumor allocation in patients with a high
pre-test probability for large tumors. Further research will
be needed to evaluate its value in challenging situation
such as prostatitis or after repeated negative biopsies.},
