摘要
目的:研究磁共振成像对前列腺癌的诊断及分期价值。方法:分析48例经手术病理证实的前列腺癌MR I资料,研究前列腺癌MR I的表现及分期,并与临床和病理分期对比。结果:MR I能显示72.9%的前列腺癌,主要为发生或累及到周围带的癌症,但无法区别局限于中央带或移行带的前列腺癌。在分期方面,它易于显示前列腺癌对精囊、周边静脉丛、膀胱及肛提肌的侵犯。在盆腔范围内分期的准确率为85.4%,优于其他影像学检查。结论:MR I能显示大多数前列腺癌,在术前分期方面有重要应用价值。
Objective： To evaluate the signifacance of MRI in the diagnosis of prostatic cancer before the operations. Methods： Data of MR imaging from 48 patients with prostatic cancer were reviewed and compared with the result of pathologic and clinical staging. Results： The accuracy of MR imaging was 72.9% in detection of prostatic cancer. Prostatic cancer located in the peripheral zone or invading the peripheral zone was readily identified with MR imaging, but it was difficult to display prostatic cancer located in the central or transitional zones. MR imaging could demonstrate periprostatic spread including the invasion of seminal vesicles, periprostatic venous plexus, bladder and the levator anus muscle with an accuracy of 85.4% in the pelvic area. Conclusion： MR imaging can demonstrate prostatic cancer located in peripheral zone and is valuable in preoperative staging.
