WB-DWI对恶性肿瘤检测价值探讨

WB-DWI value of malignant detection

目的探讨磁共振弥散加权成像(DWI)扫描技术、数字减影血管造影(DSA)在界定恶性肿瘤中的可行性和应用价值。方法回顾性分析2009年1月至2012年12月本院收治的38例脑肿瘤患者。38例患者经临床确诊后立即先后行CT和MRI扫描,并在临床治疗后2天至1个月后进行MRI复查。对比区域表观扩散系数(ADC)和表观扩散系数比例(ADCR)。结果 38例患者发病时MRI平扫T2WI未能明显显示新近病灶,而同一层面DWI 38例患者全部显示脑肿瘤强异常高信号区,脑肿瘤中心对侧镜像区(ADC值10.112±0.976)与影像半暗带区ADC值对比差异无显著性(P>0.05),与其他两个测量部位影像半暗带对侧正常区、病灶中心区对比均有显著性差异(P<0.05)。结论 DWI扫描技术和DSA技术均能及早发现恶性脑肿瘤,综合应用二者能够清晰、直观地显示患者动脉瘤的大小、分布以及是否出现出血现象等情况,因而能够在较短的时间内为下一步的治疗提供依据。

Objective To investigate DWI MRI scanning technology, DSA angiography in defining malignancies feasibility and application value. Methods A retrospective analysis of January 2009 to December 2012 in our hospital 38 cases of brain tumor patients. 38 patients clinically diagnosed immediately after successively underwent CT and MRI scans, and in the clinical treatment of 2 days to 1 month after the MRI review. Comparative regional apparent diffusion coefifcient (ADC) and apparent diffusion coefifcient ratio (ADCR). Results 38 patients when the disease T2WI MRI scan failed to show significant recent lesions, and the same level of DWI 38 Show all brain tumor patients abnormal high signal intensity area, Brain tumor center contralateral mirror area (ADC value 10.112±0.976) and penumbra image contrast was not statistically signiifcant ADC values outside (P>0.05), with the other two parts of the image measuring penumbra contralateral normal area, the central area of the lesion contrast were statistically signiifcant (P<0.05). Conclusion DWI scanning technology and DSA angiography can early detection of malignant brain tumors, integrated application capable of both clear and intuitive display size of aneurysm patients, distribution, and whether there is bleeding, etc, and thus in a short time within the next therapy.
