磁共振扩散加权成像在膀胱病变中的诊断价值探讨

Study on Value of Diffusion Weighted Imaging in Diagnosis of Bladder Lesions

目的探讨磁共振扩散加权成像对膀胱病变的诊断价值。方法整群选择自2014年3月—2015年4月该院超声检查膀胱占位患者64例。所有患者均行磁共振检查,并于10 d行膀胱病理诊断。以膀胱病理结果为参照,评估磁共振检查对膀胱良恶性病变和膀胱癌病变程度的敏感度性、特异性、准确性。结果磁共振扩散加权像对膀胱良恶性病变诊断的敏感度为100%,特异度为86.36%,准确度为95.16%。磁共振扩散加权像对膀胱恶性病变程度诊断的敏感度为100%,特异度为92.31%,准确度为95%。结论磁共振扩散加权成像可作为膀胱病变及膀胱癌浸润程度早期诊断的可靠影像学检验技术。

Objective To study the value of diffusion weighted imaging in diagnosis of bladder lesions. Methods 64 cases of patients with bladder occupying receiving ultrasonic examination in our hospital from March 2014 to April 2015 were selected, all patients were given magnetic resonance imaging, and were given bladder pathological diagnosis, the sensitivity,specificity and accuracy of magnetic resonance imaging for malignant and benign lesions of the bladder and degree of bladder cancer lesions were evaluated. Results The sensitivity, specificity and accuracy of diffusion weighted imaging in diagnosis of benign and malignant lesions of the bladder were respectively 100%, 86.36% and 95.16%, and the sensitivity, specificity and accuracy of diffusion weighted imaging in diagnosis of degree of malignant bladder lesions were respectively100%, 92.31% and 95%. Conclusion Diffusion weighted imaging can be a reliable imaging examination technology in the early diagnosis of bladder lesions and invasion of bladder.
