| 摘 要： | 目的分析瘤样炎性脱髓鞘病(TIDD)影像特点,探讨磁共振(MRI)特别是强化和弥散加权成像(DWI)检查技术对于TIDD的诊断价值。方法对16例TIDD患者行头颅CT和MRI扫描。结果病灶在头颅CT均为低信号,在MRI平扫上呈T1WI低、T2WI高信号,强化像上可见强化,57%可见开环征,发病早期DWI可见高信号,FLAIR较T1WI及T2WI能显示更清晰的病灶及范围。结论使用多种影像技术可以辅助诊断TIDD,并与脑缺血或肿瘤相鉴别,能区分病灶所处时期,因此,影像检查是诊断TIDD的有效辅诊方法之一。 |

| Abstract: | Objective To analyze the imaging characteristics of tumor-like inflammatory demyelinating diseases(TIDD).To evaluate the role of enhanced gadolinium DTPA magnetic resonance imaging(MRI)and diffusion weighted imaging(DWI)in the diagnosis and discrimination with TIDD. Methods 16 patients of TIDD were studied on MRI and/or CT scan.Results Lesions of all cases were showed hypointense signal on CT scan and TI Weighted Imaging(T1 WI)of MRI,but that were showed hyperintense signal on T2 Weighted Imaging(T2WI).Lesions could be enhanced by the method of Gd DPTA contrast.57% of them were open-ring signs.Acute lesions were identified on DWt with hyperintense signal. Conclusions MRI technology played an important role in diagnosing and staging of TIDD. |
