Previous reports on the value of magnetic resonance imaging of the prostate have been conflicting and frequently pessimistic, in part because of inability to visualize internal prostatic anatomy. Multiple spin-echo sequences were used to determine a sequence that clearly delineated the internal prostatic anatomy in normal volunteers. A thin section, T2-weighted, spin-echo technique displayed the internal prostatic anatomy in great detail, including the central and peripheral zones, the prostatic urethra, and the periprostatic venous plexus. Accurate depiction of the zonal anatomy of the prostate is important in characterizing focal prostatic disease because the vast majority of carcinomas begin within the peripheral zone, whereas benign hypertrophy originates centrally.
先前关于前列腺磁共振成像价值的报告相互矛盾，且常常较为悲观，部分原因是无法清晰显示前列腺内部结构。使用多个自旋回波序列来确定一种能清晰描绘正常志愿者前列腺内部结构的序列。一种薄层、T2加权的自旋回波技术能非常详细地显示前列腺内部结构，包括中央区和外周区、前列腺尿道以及前列腺周围静脉丛。准确描绘前列腺的分区结构对于鉴别局灶性前列腺疾病很重要，因为绝大多数前列腺癌始于外周区，而良性增生则起源于中央区。
