Development of the template prostate biopsy method with the three-dimensional space position recognition system

我们将市售前列腺癌种子植入软件的基本系统应用于传统的经会阴模板活检，建立了在前列腺三维标测中显示样本核心位置以及区分癌和非癌核心的标准程序。此外，我们还建立了叠加识别系统，从获得的岩心三维映射图中调查寒冷地区。结果表明，从样本病例来看，冷区可能位于尿道部的背侧和周围。将三维标测所预测的肿瘤体积与前列腺癌根治术后的病理肿瘤体积进行统计分析，相关性较高。

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.
