(a) Coronal MPR image (3D NerveVIEW) shows that erectile dysfunction patients had a higher T2 signal intensity and a larger nerve diameter (arrow). (b) Coronal MPR image (3D NerveVIEW) shows that the T2 signal intensity and diameter values were measured in the proximal, middle, and distal segments of the pudendal canal of the PN. (c) Coronal MPR image (3D NerveVIEW) shows the T2 signal intensity and nerve diameter of the right PN in HCs. The arrow shows the normal PN. (d) Coronal MPR image (3D NerveVIEW) shows the T2 signal intensity and nerve diameter of the left PN in HCs. The arrow shows the normal PN. (e) There were no significant differences in T2CR and diameter values of the PN (proximal, middle, and distal ends) in healthy controls between the left and right sides (all P > 0.05). (f) There were significant differences in T2CR and PN diameter values (proximal, middle, and distal ends) between the abnormal and contralateral sides in erectile dysfunction patients (all P < 0.01). (g) The T2CR values of the pudendal nerve were significantly increased in young men with ED compared with HCs (P < 0.01). ROC results showed that T2CR (AUC: 95.83%) of the PN could distinguish between young men with and without ED. (h) The diameter values of the PN were significantly increased in young men with ED compared with HCs (P < 0.01). ROC results showed that diameter values (AUC: 87.50%) of the PN could distinguish between young men with and without ED. MPR: multiplanar reconstruction; PN: pudendal nerve; HC: healthy control; ED: erectile dysfunction; T2CR: T2-weighted signal contrast ratio; ROC: receiver operating characteristic; AUC: area under ROC curve; s.d.: standard deviation; CI: confidence interval.
