早期直肠癌磁共振三维成像表现及临床应用价值研究

The Findings of MRI at 3-D for Early Rectal Cancer,and Its Clinical Application Value

目的:探讨早期直肠癌磁共振三维成像表现及临床应用价值。方法:选取本院2019-2021年早期直肠癌辅助治疗的患者120例,均行磁共振三维快速自旋回波序列(CUBE)及磁共振(MRI)常规序列扫描检查。依照患者术前术后肿瘤病理消退分级分为敏感组108例和不敏感组12例,比较2组患者新辅助治疗前后瘤体体积磁共振三维成像相关参数变化。结果:敏感组与不敏感组体积差值和体积变化率比较差异有统计学意义(P<0.05),治疗前后2组体积差值比较差异无统计学意义(P>0.05)。结论:早期直肠癌磁共振三维成像能准确检测早期直肠癌新辅助治疗前后瘤体体积变化,诊断灵敏性及准确性高,具有一定的临床应用价值。

Objective To investigate the findings of MRI at 3-D for early rectal cancer,and its clinical application value.Methods Enrolled 120patients with early rectal cancer undergoing adjuvant therapy in author’s hospital(2019-2021),and inspected them with CUBE and MRI routine order screen,afterward,according to their pathological remission grade of neoplasms between pre-and post-operation again divided them into sensitive group(108cases)and non-sensitive group(12cases);finally compared both groups’changs in relevant parameters of 3-D MRI on tumor-volume between pre-and post-adjuvant therapy.Results In volume difference-value of both groups there was no statistical difference between pre-and posttherapy(P>0.05),but between the two groups in volume difference-value and volume change ratio there was statistical difference(P<0.05).Conclusion MRI of 3-D for early rectal cancer can accurately detect out tumor volume changes between pre-and post-therapy,its sensitivity and accuracy are high,thus,has certain clinical application value.
