摘要
目的:研究分析磁共振成像(MRI)对前列腺癌的诊断及分期价值。方法:回顾分析23例经MRI检查、手术病理学检查证实的19例前列腺癌及4例前列腺增生的MRI征象。结果:23例中,术前MRI诊断前列腺癌19例,病理学检查证实15例,前列腺增生4例,假阳性4例,MRI定性诊断准确率78.9%。术前MRI诊断前列腺增生4例,手术病理学检查证实为前列腺癌。讨论:目前MRI是诊断前列腺癌较理想的检查方法,对大多数前列腺癌能够诊断,在术前分期方面具有很大的价值,对临床选择合适的治疗方案有一定重要意义。
Objective:To evaluate the magetic resonance imaging (MRI) in diagnosis and staging of prostate cancer. Methods: MRI in 23 patients with prostate diseases was retrospectively analyzed, 19 cases prostate cancer and 4 cases prostate hyperplasia proved by pathologic evidences. Results: There were 19 cases diagnosed prostate cancer by MRI before operation, including 15 cases prostate cancer and 4 cases prostate hyperplasia proved by pathologic findings after operation, and there were 4 cases diagnosed prostate hyperplasia by MRI before operation which proved to be prostate cancer by pathologic findings. There was false positive in 4 cases, and the diagnostic accuracy rate of MRI was 78.9%. Conclusion: MRI is the ideal method to diagnose prostate cancer at present, which can right diagnose to most patients with prostate cancer. MRI is useful in staging before operation and has an important role in choosing appropriate therapy.
