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.

为了提高三特斯拉(3T)磁共振成像和光谱学的质量，为前列腺癌的治疗提供有用的信息，我们检查了基于3TMR成像的解剖信息的准确性。由于良好的成像对比度，精确的前列腺区解剖以类似于组织标本的方式被可视化。此外，动态增强成像显示了副阴部动脉，这是前列腺周围正常的变异结构之一。然而，由于射频发射功率的不均匀，3T时磁共振波谱的改善非常困难，我们得到了前列腺的详细解剖结构。这将对手术前的计划有很大帮助。
