| Research Abstract |
We applied the basic system of commercially available prostate cancer seed implant software to the conventional transperineal template biopsy, and established the standard procedure to show the location of sample core as well as the distinction of cancer and non-cancer cores in the 3D mapping of the prostate. Also, we established the superposition recognition system to investigate the cold area from the obtained 3D mapping of the cores. In results, from the sample cases, cold area was likely to locate in the dorsal portion and around urethra. Statistical analysis between predicted cancer volume calculated from 3D mapping and pathological cancer volume undergoing radical prostatectomy was conducted, and high correlation was observed.
