Aim：To assess the index lesions（the largest and clinically significant ones）in cases of surgically confirmed prostate cancer（PCa）using a multi-parametric MRI at 3 tesla and to evaluate the relationships between the clinical-pathological features of index PCas and cancer visualization.
Materials and Methods：This retrospective study included 67 patients who had undergone roboticassisted radical prostatectomy. Two radiologists reviewed the MRIs（axial and coronal T2-weighted imaging, diffusion-weighted imaging（DWI）with apparent diffusion coefficient mapping and dynamic contrast enhancement MRI（DCEI））. The patients were divided into 4 groups as follows：detected on all 3 sequences（A）, on 2 of 3 sequences（B）, on 1 of 3 sequences（C）, and on none of them（D）. In all groups, all PCa characteristics were assessed, including the PSA level, Grade Group（GG）based on the Gleason score（GS）, the D’Amico criteria, and the maximum tumour length（TL）of the biopsy specimen.
Results：Of the 67 patients, 16 were high-risk according to the D’Amico criteria, and 15 of these 16 high-risk patients（94％）belonged to either Group A or Group B. In addition, the mean TL and GG were longer and higher, respectively, in Group A than in the other groups（p＜0.05）. Furthermore, in Group B, 3 of the 4 high-risk patients（75％）were detected using DWI and DCEI. The lesions detected using DWI and DCEI had higher GSs and were in a higher GG.
Conclusion：PCas of pathologically higher grades and clinically higher risk were more readily detectable
using multiple parameters. |
