Prostate cancer in an aging society: What does MRI technology tell us about determining appropriate therapies?

本研究的目的是提高三种特斯拉（3T）磁共振成像和光谱的质量，其信息有助于确定前列腺癌的治疗。我们检查了基于3TMR成像的解剖信息的准确性。由于出色的成像对比，精确的前列腺分区解剖以类似于组织学标本的方式可视化。此外，动态增强成像显示阴部副动脉，前列腺周围正常变异结构之一。然而，由于发射射频功率的不均匀性，在3T下提高MR光谱是非常困难的。我们获得了详细的前列腺解剖结构。这将有助于术前计划。

The purpose of this study was to improve the quality of three Tesla (3T) MR imaging and spectroscopy, whose information is helpful for determining the management of prostate cancer.We examined the accuracy of anatomical information based on 3TMR imaging. Due to the excellent imaging contrast, the precise prostatic zonal anatomy was visualized in an analogous fashion to histological specimens. Further, dynamic contrast enhanced imaging demonstrated the accessory pudendal artery, one of the periprostatic normal variant structures. However, improvement of MR spectroscopy at 3T was very difficult because of the inequality of transmitted radiofrequency power.We obtained the detailed anatomical structure of prostate. This will contribute greatly to pre-surgical planning.
