| 目的 探讨扩散加权成像(DWI)对病毒性脑炎、急性播散性脑脊髓炎的鉴别诊断价值。 方法 对10例病毒性脑炎和10例急性播散性脑脊髓炎病例行常规MRI和DWI检查。测量并计算DWI的表观扩散系数(ADC)值和相对表观扩散系数(rADC)值并以SPSS 10.0统计软件进行统计学分析。 结果 病毒性脑炎平均ADC值和rADC值分别为(0.95±0.28)×10-3 mm2/s 和(1.07±0.31),急性播散性脑脊髓炎平均ADC值和rADC值为(1.38±0.25)×10-3 mm2/s和(1.80±0.34)(P<0.01)。 结论 DWI的ADC值和rADC值能较好地鉴别病毒性脑炎与急性播散性脑脊髓炎。 |

| Objective To explore the value of diffusion weighted imaging (DWI) in the differential diagnosis between viral encephalitis and acute disseminated encephalomyelitis (ADEM). Methods Ten patients with viral encephalitis and another 10 patients with ADEM underwent conventional MRI and DWI before treatments. The apparent diffusion coefficient (ADC) values and relative apparent diffusion coefficient (rADC) values of the two groups were calculated and statistically analyzed with software SPSS 10.0. Results The mean ADC value and rADC value were (0.95±0.28)×10-3 mm2/s and (1.07±0.31) in the viral encephalitis, respectively, but (1.38±0.25)×10-3 mm2/s and (1.80±0.34) in the ADEM, respectively (P<0.01). The ADC value and rADC value of the viral encephalitis were lower than those of ADEM. Conclusion DWI may play an important role in the differential diagnosis between viral encephalitis and ADEM. |
