CT、MRI对急性脑梗塞患者早期诊断意义比较

目的研究比较CT和MRI对急性脑梗塞的早期诊断临床价值,为临床治疗提供参照。方法选择对照研究的方式对内科收集治疗的65例急性脑梗塞患者进行比较,所有患者均在发病后6h内行颅脑CT和MRI检查,以对病情作出判断,对比两种诊断方式的优劣。结果 CT检查确诊率为69.23%,在CT基础上联合MRI检查确诊率为96.92%,二者比较差异明显(P0.05)。两种检查方式检出病灶位置为脑叶、基底节及小脑,MRI可检查出脑干梗塞,但CT未检出。两种检查方式检出病灶直径比较,P0.05,差异显著。结论急性脑梗塞早期采用MRI进行诊断能够清晰显示发病部位、形态及大小,有利于临床对疾病作出早期诊断;联合CT诊断具有较高的诊断准确率,具有广阔的临床应用前景。

Comparison in Early DiagnosisSigniifcance between CT and MRI on Patients with Acute Cerebral Infarction

Objective This paper is to investigate and compare clinical value of CT and MRI in early diagnosis of acute cerebral infarction and to provide the reference for clinical treatment.Methods Sixty five patients admitted by the Department of Internal Medicine in the manner of controlled study were compared, all patients were subject to craniocerebral CT and MRI examination in 6 hours after attacks of diseases to determine conditions of disease, and advantages and disadvantages of two diagnostic modewere compared.Results The diagnosis rate of CT examination was 69.23%,and that of combined MRI on the basis of CT was 96.92%, thedifference was significant when two methods were compared (P<0.05). The detected lesion locations of two examination modes were the lobe, basal ganglia and cerebellum, MRI could detect brainstem infarction, but CT failed to detected it. The comparison in the diameter of detected lesion via two examination method satisfied P<0.05, and the difference was significant.Conclusion MRI diagnosis applied in early acute cerebral infarction can clearly display the position, shape and size, being conductive to clinically early diagnosis on disease. Combined CT diagnosis is of high diagnosis accuracy and wide prospect of clinical applications.
