目的探讨前列腺外周带癌3.0T MRI表现。方法对32例手术或穿刺病理证实的前列腺外周带癌的3.0T MRI表现进行回顾性分析。结果前列腺外周带癌直接征象:T2WI上呈局部或弥漫性低信号,腺泡状结构破坏,前列腺包膜受侵。前列腺外周带癌间接征象:前列腺癌包膜外侵犯精囊腺、周围神经血管束、膀胱、直肠,并可造成盆腔骨质及淋巴结转移。结论3.0T磁共振对前列腺外周带癌的诊断具有重要价值。
Objective To investigate the 3.0T MRI findings of peripheral prostate cancer. Methods Retrospective analysis of 3.0T MRI findings of peripheral prostate cancer in 32 cases with surgically or punctured pathology was retrospectively analyzed. Results Prostate peripheral cancer with direct signs: T2WI showed a local or diffuse low signal, acinar structure damage, prostate capsule invasion. Indirect prostate cancer with indirect signs of prostate cancer: extracapsular invasion of seminal vesicles, peripheral nerve vascular bundles, bladder, rectum, and can cause pelvic bone and lymph node metastasis. Conclusion 3.0T magnetic resonance imaging of peripheral prostate cancer has important value.
