目的:探讨磁共振成像(MRI)在前列腺癌诊断中的作用。方法:对55例经前列腺活检证实为前列腺疾病患者(包括前列腺癌25例,非前列腺癌30例)进行了MRI检查,并将MRI检查结果与经直肠超声(TRUS)检查结果进行比较。结果:MRI和TRUS对前列腺癌诊断的准确率分别为75.0％和71.4％,两者差异无显著性意义。结论:MRI是评价前列腺癌的一种较好的影像学方法,有助于前列腺癌的临床分期。
Objective: To investigate the role of magnetic resonance imaging (MRI) in the diagnosis of prostate cancer. Methods: Fifty-five patients with prostatic diseases confirmed by prostatic biopsy (including 25 cases of prostate cancer and 30 cases of non-prostate cancer) were examined by MRI. The results of MRI and transrectal ultrasound (TRUS) were compared. Results: The diagnostic accuracy rates of MRI and TRUS for prostate cancer were 75.0% and 71.4% respectively, with no significant difference between the two groups. Conclusion: MRI is a good imaging method for evaluating prostate cancer and is helpful for the clinical staging of prostate cancer.
