多模态磁共振判断膀胱癌肌层浸润的价值

目的 探讨基于多模态磁共振成像上T2WI联合DWI+T2 SPAIR序列在判断膀胱癌肌层浸润价值与病理诊断结果的一致性。 方法 收集2020年3月~2022年3月因患有膀胱肿瘤在我院行磁共振检查并取得病理结果的患者60例，均行T2WI联合DWI序列、T2WI联合T2 SPAIR、DWI序列联合T2 SPAIR及T2WI联合DWI+T2 SPAIR序列检测。计算不同组合序列的检测结果对膀胱癌肌层是否受侵分期的检查效果及一致性评估。 结果 T2WI联合DWI+T2 SPAIR序列对肌层有无浸润的特异性、敏感度与准确度分别为95.46%(21/22)、89.47%(34/38)、91.67%(55/60)，明显高于T2WI联合DWI序列、T2WI联合T2 SPAIR及DWI序列联合T2 SPAIR，差异有统计学意义(P < 0.05)；T2WI联合DWI+T2 SPAIR序列与病理诊断结果的一致性最高。 结论 T2WI联合DWI+T2 SPAIR序列扫描方案可明显提高对膀胱癌T分期的诊断准确率，且T2WI联合DWI+T2 SPAIR序列与病理诊断结果的一致性最高，更有利于评估病灶肌层浸润情况。

Multimodal magnetic resonance was used to determine the value of muscular invasion in bladder cancer

  Objective   To evaluate the value of T2 SPAIR sequence combined with T2WI + DWI in determining muscle layer invasion of bladder cancer based on multimodal MRI (mpMRI).   Methods   Sixty patients with bladder tumor who underwent magnetic resonance examination and obtained pathological results in our hospital from March 2020 to March 2022 were collected. T2WI combined with DWI sequence, T2WI combined with T2 SPAIR, DWI combined with T2 SPAIR and T2WI combined with DWI + T2 SPAIR sequence were detected. The results of different combination sequences were calculated to evaluate the efficacy and consistency of muscularis invasion stage of bladder cancer.   Results   The specificity, sensitivity and accuracy of T2WI combined with DWI+T2 SPAIR sequences for muscle layer infiltration were significantly higher than T2WI combined with DWI, T2WI combined with T2 SPAIR and DWI combined with T2 SPAIR(P < 0.05). SPAIR sequence of T2WI combined with DWI+T2 had the highest consistency with pathological diagnosis.   Conclusion   T2 SPAIR combined with DWI+ T2 SPAIR sequence scanning can significantly improve the diagnostic accuracy of T stage of bladder cancer, and T2WI combined with DWI+T2 SPAIR sequence has the highest consistency with pathological diagnosis, which is more conducive to the evaluation of muscle layer infiltration of lesions.
