宫颈癌行磁共振灌注加权成像诊断的表现特点分析

Analysis of the Performance Characteristics of Magnetic Resonance Perfusion Weighted Imaging Diagnosis of Cervical Cancer

目的:分析磁共振灌注加权成像诊断宫颈癌的表现特点。方法:研究时间为2015年11月~2020年11月。经磁共振灌注加权成像获取26例正常宫颈、26例宫颈肌壁间肌瘤、28例宫颈癌患者的TTP(达峰时间)、SSmax(首过最大灌注斜率)、ME(最大增强)、TIC(时间-信号强度曲线),分析血流动力学特征、灌注特性相关性。结果:宫颈癌组SSmax高于肌瘤对比组和正常宫颈组,ME、TTP参数值均低于肌瘤对比组和正常宫颈组(P<0.05)。结论:磁共振灌注加权成像诊断宫颈癌能够不同程度反映毛细血管通透性、血流灌注,鉴别诊断宫颈癌价值较高。

Objective:To analyze the performance characteristics of magnetic resonance perfusion weighted imaging in the diagnosis of cervical cancer.Method:The research period is from November 2015 to November 2020.TTP(time to peak),SSmax(first pass maximum perfusion slope),ME(maximum enhancement),TIC of 26 normal cervix,26 cervical intramural fibroids,and 28 cervical cancer patients were obtained by magnetic resonance perfusion weighted imaging(Time-signal intensity curve),analyze the correlation of hemodynamic characteristics and perfusion characteristics.Results:The SSmax of the cervical cancer group was higher than the fibroids comparison group and the normal cervix group,and the ME and TTP parameter values were lower than the fibroids comparison group and the normal cervix group(P<0.05).Conclusion:Magnetic resonance perfusion weighted imaging in the diagnosis of cervical cancer can reflect capillary permeability and blood perfusion to varying degrees,and it is of higher value in the differential diagnosis of cervical cancer.
