The authors retrospectively reviewed 140 MR examinations of the prostate to assess the presence of similar findings in the different patients affected with the same prostatic disease. In 35 patients with acute phlogosis, MR imaging showed enlargement of peripheral gland, with increased signal intensity on T2-weighted images, while reduced peripheral gland with low signal intensity was demonstrated in chronic phlogosis. Five patients presented roundish cystic lesions, with clear-cut outlines, clearly distinguishable from the surrounding parenchyma. Benign Prostatic Hyperplasia (BPH) was observed in 32 cases. 52% of them had multiple nodules with high signal intensity, 40% had hyperintense enlarged central glands, with no evidence of BPH nodules, and the remaining 8% presented single/multiple nodules with low signal intensity. In 56 patients with prostatic carcinoma the tumor extent ranged from 18-20 mm nodules to 5-6 cm masses with involvement of periprostatic adipose tissue or surrounding organs. The smallest lesions were always found in the peripheral gland and had low signal intensity on T2-weighted sequences. In spite of the different findings in the patients affected with BPH, the study proved MR imaging to be able to distinguish the various patterns of the different prostatic diseases.
作者回顾性分析了140例前列腺的磁共振成像检查，以评估患有相同前列腺疾病的不同患者中是否存在相似的表现。在35例急性炎症患者中，磁共振成像显示外周腺增大，在T2加权图像上信号强度增加，而在慢性炎症中则显示外周腺缩小，信号强度降低。5例患者出现圆形囊性病变，轮廓清晰，与周围实质明显区分。32例患者观察到良性前列腺增生（BPH）。其中52%有多个高信号结节，40%有高信号的增大中央腺，无BPH结节证据，其余8%有单个/多个低信号结节。在56例前列腺癌患者中，肿瘤范围从18 - 20毫米的结节到5 - 6厘米的肿块，累及前列腺周围脂肪组织或周围器官。最小的病变总是在外周腺中发现，在T2加权序列上信号强度低。尽管BPH患者有不同表现，但该研究证明磁共振成像能够区分不同前列腺疾病的各种模式。
