背景抑制磁共振弥散成像技术在子宫内膜癌腹腔镜手术中的应用分析

Applications of diffusion-weighted imaging with background suppression(DWIBS) in endometrial carcinoma and laparoscopy

目的探讨背景抑制磁共振弥散成像(DWIBS)技术在子宫内膜癌腹腔镜手术中的应用价值。方法120例子宫内膜癌患者接受盆腔常规核磁检查及DWIBS扫描,测量肿瘤实质、淋巴结的表观弥散系数值(ADC值)。其中Ⅰ期患者74例,37例行腹腔镜手术,37例行开腹手术。比较两组手术情况和生存情况。结果术前分期与术后分期总符合率93.33%。DWIBS检查瘤灶显示准确率96.67%,淋巴结显示准确率86.67%。腔镜组和开腹组生存率比较差异无显著性。结论背景抑制磁共振弥散成像在显示病灶和淋巴结方面有一定优势,对于子宫内膜癌的术前分期有一定指导意义。以此为指导对子宫内膜癌患者实施腹腔镜手术是切实可行的。

【Objective】To evaluate the value of diffusion weighted imaging with background suppression（DWIBS） in endometrial carcinoma and laparoscopy.【Methods】120 cases clinically and pathologically confirmed endometrial carcinoma performed conventional MR and DWIBS.The ADC values of tumor parenchyma and metastatic lymph nodes were measured.There were 37 cases operated by laparoscopy in 74 cases,and the other 37 cases were operated conventional.Compared to the state of operation and survival between two groups.【Results】The coincidence was 93.33% between the preoperative stage and post-operation.Demonstration rate of malignant lesion and lymph node was 96.67% or 86.67% in DWIBS respectively.The difference of the operation between open abdomen and laparoscopy was no significant.【Conclusion】The diffusion weighted imaging with background suppression（DWIBS） has the dominance invariably in displaying malignant lesion and lymph node,and it has significance in guiding the preoperative stage of endometrial carcinoma.It is feasible to guide the laparoscopy operation on endometrial carcinoma patients by DWIBS.
