Results
The sensitivity, specificity, positive predictive value, negative
predictive value, positive likelihood ratio, negative likelihood ratio,
and the accuracy of mpMRI and 68Ga-PSMA PET/MRI are
shown as 55.7%, 91.8%, 80.6%, 77.2%, 78.1% and 60.8%, 94.3%,
86.8% 79.8%, 83.5%, respectively. 68Ga-PSMA PET/MRI
has higher sensitivity and specificity compared with mpMRI. However, no
statistically significant difference was found (p = 0.464).
Combined imaging had significantly higher diagnostic accuracy compared
with mpMRI and 68Ga-PSMA PET/MRI (change in AUC: 0.084
and 0.046, p < 0.001 and p = 0.028,
respectively), while no statistically significant difference was found
between mpMRI and 68Ga-PSMA PET/MRI (change in AUC:
0.038, p = 0.246).
