| 摘 要： | 目的:评价MR背景信号抑制弥散加权成像(DWIBS)对宫颈癌的诊断与分期价值。方法:收集病理诊断为宫颈癌的患者17例,常规MRI检查后,行DWIBS成像,并对DWIBS原始图像进行薄层及厚层最大密度(MIP)多平面重建。结果:DWIBS像上15例显示肿瘤,肿瘤在类PET像上较周围正常结构呈明显低(黑)信号,常规MRI有13例显示肿瘤;7例DWIBS显示肿瘤的周围侵犯或阴道受侵,4例显示盆腔淋巴结转移。结论:DWIBS成像较常规MRI更容易显示宫颈癌及其周围侵犯和盆腔淋巴结转移。

| Abstract: | Objective:To estimate the value of diffusion weighted imaging with background body signal suppression(DWIBS) in diagnosis of cervical carcinoma and its staging.Methods:17 patients with cervical carcinoma diagnosed by pathology were performed with the conventional MRI sequences and DWIBS,and then,the images of DWIBS were reconstructed by minimum intensity projection(MIP) in both thick layer and thin layer.Results:DWIBS showed primary tumor that was hypo-singal or black-singal in 15 cases of patients,while,th... |
