假瘤型脱髓鞘病的核磁共振特点研究

Study on Magnetic Resonance Imaging Characteristics of Demyelinating Pseudotumor Lesions

目的观察假瘤型脱髓鞘病的核磁共振特点,提高甲瘤型脱髓鞘病的临床诊断准确率。方法选取假瘤型脱髓鞘病患者30例作为病例组,选取脑胶质瘤患者30例、脑脓肿患者30例以及中枢神经系统淋巴瘤患者16例分别作为对照组1、对照组2和对照组3。将病例组患者的MRI资料分别为对照组1、对照组2和对照组3患者的MRI资料进行对比研究。结果病例组30例开环征数量高于对照组1、2、3(P<0.05)。病例组与3个对照组相比,其诊断灵敏度、特异度、阳性预测值和阴性预测值分别为66.67%、86.84%、66.67%和86.84%。结论临床对于假瘤型脱髓鞘病患者进行诊断需结合其他病理特点、临床表现以及影像学特征进行综合考虑,且开环征能够为假瘤型脱髓鞘病与肿瘤性疾病及感染性疾病的鉴别诊断提高更多的参考依据。

Objective To observe the magnetic resonance imaging characteristics of the tumor type and to improve the diagnostic accuracy of the tumor. Methods 30 cases of patients with 30 cases of brain glioma, 30 cases of brain abscess and 16 cases of central nervous system lymphoma were selected as the control group 1, control group 2 and control group 3. The MRI data of patients in the case group were compared with the control group 1, control group 2 and the control group of 3 patients with MRI data. Results The number of open loop in the case group was significantly higher than that in control group 1, 2, 3（P 0.05）. The diagnostic sensitivity, specificity, positive predictive value and negative predictive value were 66.67%,86.84%, 66.67% and 86.84% compared with the 3 control groups. Conclusion The clinical diagnosis of the patients with pseudo tumor type of patients with other pathological features, clinical manifestations and imaging features are considered, and the open loop can be a false tumor type of disease and infectious diseases and infectious diseases to improve the differential diagnosis of more reference basis.
