核磁共振成像技术在子宫肿瘤诊断上的成像特征分析

摘要

目的：探讨核磁共振技术在子宫肌瘤成像的分析。方法：对26例子宫肌瘤患者行MRI检n　　查，S E 序列，横断面T1、T2加权及矢状面、冠状面T2加权成像，并对图像进行分析。结果：子宫肌瘤患者检出42个病灶，分别为圆形、类圆形、椭圆形、不规则分叶状，子宫呈现均有不同程度增大，宫腔变形。T1 WI上大多数病灶呈中低信号，T2 WI 上瘤体信号低或混杂信号。结论：MRI 对子宫肌瘤在观察大小、形态、位置与子宫腔的关系和肌瘤在定性方面上有较高的诊断价值，临床上值得推广应用。%Objectives:To research the imaging feature analysis of magnetic resonance imaging in the diag-nosis of uterine tumor.Methods:26 patients were examined with uterine fibroids MRI,SE sequence,cross-sec-tional T1 ,T2 -weighted and sagittal,coronal T2 -weighted imaging and the image analysis was conducted. Results:42 lesions were detected from uterine fibroids patients,the shapes of which were round,oval,elliptical and irregular lobulated.The imaging of uterus indicated varying degrees of increased uterine deformation.Most le-sions on T1 WI showed low signal.T2WI’s signal on tumor showed low or mixed signals.Conclusion:MRI obser-vation of uterine fibroids in size,shape,position and relationships with fibroid uterine cavity has a high diagnostic value,which should be widely applied clinically.
