早期腔隙性脑梗死行CT和MRI检查的临床诊断价值

Clinical diagnostic value of lacunar cerebral infarction underwent CT,MRI examination

目的调查分析早期腔隙性脑梗死影像特点,探讨CT与MRI两种检查方法诊断腔隙性脑梗死的临床价值。方法选择2012年1月-2012年12月入住院神经内科的早期腔隙性脑梗死患者82例,回顾性收集患者的临床资料,CT和MRI检查结果,分析两种检查方法的检出情况。结果 CT和MRI方法均可以检出早期腔隙性脑梗死病灶,其中CT检出145个病灶,MRI检出742个病灶,MRI检出的病灶数目是CT的5.12倍;病灶直径>5mm时,CT检出142个,MRI检出的病灶486个,检出直径<5mm的病灶,CT检出率为2.07%(3/145),MRI检出率为34.50%(256/742),差异有统计学意义(P<0.05);腔隙性脑梗死的不同病灶部位两种检查方法检出率有差异(χ2=147.02,P<0.05)。结论 CT、MRI影像学检查可应用于早期腔隙性脑梗死的诊断,MRI方法较CT更清晰准确发现腔隙性脑梗死患者的早期、微小病灶,是临床诊断早期腔隙性脑梗死的重要方法。

Objective Investigation and analysis of the image features of early brain lacunar infarction,To investigate the clinical value of diagnosis of lacunar cerebral infarction by MRI and CT .Methods Select 82 cases of lacunar cerebral infarction from the hospital in 2012 January to December,Patients’s clinical data、CT and MRI examination results were retrospectively collected,Analysis the detection of two methods of inspection.Results The CT and MRI methods can be detected early brain lacunar infarction lesions,CT detected 145 lesions,and 742 lesions were detected with MRI,The number of lesions detected by MRI was 5.12 times of CT;Lesion diameter is less than 5mm,CT detected 142 lesions and MRI detected 486 lesions,The detection of lesions less than 5mm in diameter,the detection rate of CT was 2.07%,MRI’detection rate was 34.50%,the difference was statistically significant（P 〈0.05）;Two methods for examination of different lesion’s detection rate are difference（P 〈0.05）.Conclusion Early diagnosis can be applied in lacunar cerebral infarction by CT,and MRI,MRI more clearly and accurately found early,small lesions in patients with lacunar cerebral infarction,is an important method for early clinical diagnosis of lacunar cerebral infarction.
