摘要
目的探讨神经胶质瘤多层螺旋CT(MSCT)、核磁共振(MRI)图像表现及诊断价值。方法对2016年1月至2018年8月于我院就诊治疗的52例神经胶质瘤患者的临床病例及影像学资料进行回顾性分析,根据资料可知所有患者入院均经MSCT和MRI等相关影像学检查,分析不同检查方法对神经胶质瘤的诊断价值,并整理神经胶质瘤在不同检查方法中的影像图像特征。结果但MRI检查对脑神经胶质瘤诊断符合率(96.15%)显著高于MSCT检查对脑神经胶质瘤检出的诊断符合率84.61%(P<0.05)。在MSCT平扫检查中,绝大部分患者表现为低密度、混杂密度以及高密度的圆形或椭圆形包块,边界可显示清晰或不清楚,部分呈浸润性生长,其中28例检查示肿瘤内表现为小斑片点状、弧状以及结节状钙化,12例瘤体整体钙化。进一步增强扫描检查示轻~中度强化、坏死部分无强化。MRI常规扫描检查中主要表现为弥漫性斑片状改变,在T1WI上主要呈现为低、等信号,在T2WI及FLAIR均以高信号显示,且肿块边界不清,肿块周围脑组织显示肿胀,脑沟变浅、变平,脑室可轻微变窄,未见明显坏死和所有病例均无坏死和钙化;进一步增强扫描检查示40例患者未见明显强化,12例表现为小结节状强化。结论较MSCT检查而言,MRI对神经胶质瘤检出率与其类似,但对其诊断符合率显著高于MSCT检查,更能准确的反映肿瘤病变范围和病理特点,更有利于指导临床进行治疗和改善其预后效果。
Objective To investigate the image features and diagnostic value of multislice spiral CT(MSCT)and magnetic resonance imaging(MRI)for glioma.Methods The clinical and imaging data of 52 patients with glioma who were treated in our hospital from January 2016 to August 2018 were retrospectively analyzed.According to the data,all patients were admitted to the hospital undergoing relevant imaging examinations such as MSCT and MRI.The diagnostic value of different examination for glioma was analyzed,and the image features of glioma in different examination were organized.Results However,the coincidence rate of MRI examination for glioma of brain(96.15%)was significantly higher than that of MSCT(84.61%)(P<0.05).In the MSCT plain scan,the vast majority of patients showed circular or elliptical masses of low-density,mixeddensity and high-density,with clear or unclear boundaries and partially invasive growth.Among them,28 cases showed that the tumor showed spotted,arcuate and nodular calcification,and 12 cases showed overall calcification.Further enhanced scanning showed mild to moderate enhancement and no enhancement in necrotic areas.Routine scanning of MRI mainly showed diffuse and patchy changes,mainly showed low and equal signals in T1WI,and mainly showed high signals in T2WI and FLA IR.And the boundaries of the tumor are unclear.The brain tissue around the mass showed swelling.The sulus became shallow and flattened,the ventricles were slightly narrowed,the obvious necrosis was not observed,and all cases did not show necrosis and calcification.Further enhanced scanning showed that 40 patients did not show obvious enhancement,and 12 patients showed small nodular enhancement.Conclusion Compared with MSCT,MRI has a similar detection rate for glioma,but its coincidence rate of diagnosis is significantly higher than that of MSCT.It can more accurately reflect the range of lesions and pathological features,and is more favorable to guide clinical treatment and improve its prognosis.
