Previous reports of magnetic resonance imaging of the prostate have described a homogeneous appearance to the normal prostate gland. The T2-weighted images of the normal prostate obtained at higher field strength (1.5 T) reveal an inhomogeneous appearance of the normal gland, with apparent differentiation of normal prostatic zones having differing histology. The anterior fibromuscular tissue of the normal prostate, the glandular tissue comprising the central zone of the prostate, and the glandular tissue of the peripheral zone of the prostate can be differentiated by differences in intensity in the T2-weighted images. The ability to differentiate histologically distinct regions of the normal prostate may be important since clinically important prostatic diseases (benign prostatic hypertrophy and carcinoma) arise in different prostatic zones.
先前有关前列腺磁共振成像的报告描述了正常前列腺腺体呈均匀外观。在更高场强（1.5T）下获得的正常前列腺的T2加权图像显示正常腺体呈不均匀外观，具有不同组织学特征的正常前列腺区域有明显差异。正常前列腺的前部纤维肌肉组织、构成前列腺中央区的腺组织以及前列腺外周区的腺组织可通过T2加权图像中的强度差异来区分。能够区分正常前列腺组织学上不同的区域可能很重要，因为临床上重要的前列腺疾病（良性前列腺增生和癌）发生在不同的前列腺区域。
