分析32例经手术病理证实为前列腺癌的MRI资料及临床资料,着重研究前列腺癌对周围组织侵犯及转移的MRI征象。结果32例中,MRI显示包膜侵犯19例,神经血管束(NVB)侵犯20例;精囊侵犯23例;周围脂肪受侵8例;侵及周边静脉丛10例;侵及闭孔内肌、提肛肌5例;侵及膀胱、后尿道及直肠前壁10例;淋巴结转移21例;骨转移19例。表明MRI是评价前列腺癌对周围组织侵犯及转移的较好的影像学检查方法,可明显提高前列腺癌的定性诊断和分期诊断的准确性。
MRI data and clinical data of 32 cases of prostate cancer confirmed by operation and pathology were analyzed. The MRI signs of invasion and metastasis of surrounding tissues by prostate cancer were mainly studied. Results Of the 32 cases, 19 cases were found by MRI and 20 cases by neurovascular bundle (NVB), 23 cases were caused by seminal vesicle, 8 cases were caused by peripheral fat invasion, 10 cases were invading peripheral venous plexus, Levator ani muscle in 5 cases; invaded the bladder, posterior urethra and anterior rectum in 10 cases; lymph node metastasis in 21 cases; bone metastases in 19 cases. This shows that MRI is a good imaging method to evaluate the invasion and metastasis of prostate cancer to surrounding tissues. It can significantly improve the accuracy of diagnosis and staging of prostate cancer.
