摘　　要：目的 探索前列腺癌早期MRI表现及局部分期诊断中的价值。方法 回顾性总结64例原发前列腺恶性肿瘤,对照病理、临床资料,分析MRI影像特征和局部分期情况。结果 肿瘤的MRI检出率93.8％(60/64),分期诊断(依照Whitmore-Jewelt分法)正确率占86.2％(56/644)。早期(B期)包膜下局限灶(如<1.5cm结节或肿块)占37.5％(24/64),诊断包膜侵犯并突破的敏感性、特异性和准确率分别为88.6％、100％和93.8％。结论 MRI在前列腺检查中,具有早期诊断和准确局部分期的重要价值。Purpose To explore the value of MRIin early diagnosis and local staging of the primary prostatic carcinoma. Methods 64 cases of prostatic carcinoma underwent MRI at 1. 5T, that findings and local staging of MRI were analyzed retrospectively, compared with pathology results and clinic data. Results The carcinoma detection rate was 93.8% . The accurate rate of local staging (based on Whitmore - Jewell) by MRI was 86.2%(56/64) . The early lesions (stage B) as nodule( < 1.5cm) or mass which under capsule were 37.5% (24/64) . The sensitivity,specificity and accuracy of MRI in diagnosing of invasions into and beyond the prostatic capsule were 88.6 % ,100 % and 93. 8 % respectively. Conclusion MRI is much valuable in the early diagnosing and accurate local staging of prostatic carcinoma.
