【摘要】：目的探讨磁共振各向同性容积扫描(CUBE)成像技术在颞叶癫痫(TLE)脑内病变检测的临床应用价值。方法搜集2015年6月至2016年9月本院临床诊断为癫痫患者30例,年龄7~65岁,平均31.7岁。均行MRI扫描,扫描序列包括矢状位T_1FLAIR,轴位T_1FLAIR、T_2WI及T_2FLAIR,冠状位3D CUBE T_2WI、T_2FLAIR及3D BRAVO。扫描后3D CUBE图像经多层面重组技术合成多方位及多种厚度的2D影像,与常规MRI对病变的显示能力进行比较,采用SPSS 17.0进行处理分析,经卡方检验,P0.05认为差异有统计学意义。结果 30例患者中,3D CUBE重组图像发现脑内阳性病灶29个,而常规MRI发现阳性病灶15个,3D CUBE技术比常规MRI的敏感度高46.7%(P0.05),差异有显著意义。结论由于颞叶相邻结构复杂,当致痫灶病理改变不明显时,应运用3D CUBE扫描技术,然后采取多角度及薄层高分辨2D重组图像,有利于颅内颞叶病变的检出。
[Abstract]:Objective to evaluate the clinical value of magnetic resonance isotropic volume scanning (CUBEB) imaging in the detection of brain lesions in temporal lobe epilepsy (TLEs). Methods from June 2015 to September 2016, 30 patients with epilepsy, aged 765 years, with an average age of 31.7 years, were collected. All MRI scans were performed with sagittal T _ 1FLAIRI, T _ 1F _ LAIRI T _ 2WI and T _ 2F _ LAIRI, 3D CUBE T _ 2W _ Iar _ T _ 2FLAIR and 3D Bravo. After scanning 3D CUBE images were synthesized into multi-directional and multi-thickness 2D images by multi-level recombination technique, and compared with conventional MRI, SPSS 17.0 was used to process and analyze the lesions. The chi-square test showed that the difference was statistically significant. Results among the 30 patients, 29 lesions were found in brain by 3D CUBE reconstruction, while 15 lesions were detected by conventional MRI. The sensitivity of 3D CUBE was 46.7% higher than that of conventional MRI (P 0.05). Conclusion because of the complex adjacent structure of temporal lobe, 3D CUBE scanning technique should be used when the pathological changes of epileptogenic foci are not obvious, and then multi-angle and thin-layer high-resolution 2D recombination images can be used to detect intracranial temporal lobe lesions.
