摘要
目的：探讨MRI在膀胱癌的术前诊断及分期的应用价值。材料与方法：搜集20例采用0.5T磁共振扫描仪检查，经手术病理证实的膀胱癌，分析其MRI表现。结果：根据肿瘤的MRI表现将其分为腔内型、浸润型和腔外型。术前MRI诊断与TNM分期符合率为80％（16／20）,MRI较病理分期偏高。结论：T1加权像主要用于肿瘤的定性诊断，T2加权像主要用于肿瘤的术前分期；MRI与病理分期有较高的符合性。
Objective: To investigate the practical value of MRI in the peperahve hong and diagnosis of urinary bladder cancer. Materisls and Methods: MRI findings in 20 cases with surgically and pathologically-proved bladder cancer were analyzed. Results: Based on MRI findings, bladder cancer was diveded into three types: (1) intra-cavity type(n = 15); (2) infiltrating type (n = 3); and (3) extra-cavity type (n = 2).Agrement in Staging of preoperative MRI and pathalop was found in 80% (16/20), ed the edng with MRI was a little bit higher than that with pathology. Conclusion: T1WI is useful mainly in qualitative diguis, while T2WI in preoperative staging. MRI staging is well commpatible with pathological staging.
