abstract = {To compare [68Ga]PSMA-11 PET-CT, [68Ga]PSMA-11 PET-MRI and
MRI in a cohort of prostate cancer (PCa) patients in
biochemical recurrence after initial curative
therapy.Fifty-three patients with biochemically recurrent
PCa underwent whole-body [68Ga]PSMA-11 PET-CT 1 hour
post-injection (p.i.) followed by [68Ga]PSMA-11 PET-MRI 2.5
hours p.i., including a multiparametric MRI pelvic protocol
examination. Imaging data analysis consisted of visual
(qualitative) evaluation of the PET-CT, PET-MRI and MRI
scans, as well as semi-quantitative and quantitative
analyses of the PET and MRI data, including calculation of
the parameters standardized uptake value (SUV) and apparent
diffusion coefficient (ADC) derived from the PCa lesions.
Association analysis was performed between imaging and
clinical data, including PSA level and Gleason score. The
results were considered significant for p-values less than
0.05 (p < 0.05).The hybrid imaging modalities [68Ga]PSMA-11
PET-CT and PET-MRI were positive in more patients than MRI
alone. In particular, PET-CT detected lesions suggestive of
PCa relapse in 34/53 $(64.2\%),$ PET-MRI in 36/53 $(67.9\%)$
and MRI in 23/53 patients $(43.4\%).$ While no significant
differences in lesion detection rate were observed between
PET-CT and PET-MRI, the latter was particularly efficient in
detection of local recurrences in the prostate bed mainly
due to the contribution of the MRI part of the modality.
Association analysis revealed a statistically significant
increase in the probability of a positive scan with
increasing PSA levels for all imaging modalities.
Accordingly, there was no significant association between
scan positivity rate and Gleason score for any imaging
modality. No significant correlation was observed between
SUV and ADC values in lymph node metastases.[68Ga]PSMA-11
PET-CT and PET-MRI provide equally good detection rates for
PCa recurrence, both outperforming stand-alone MRI.},
