摘要

目的 观察MRI在疑似急性缺血性脑梗死患者诊断中的敏感性及准确性。方法 收集本院收治的疑似急性缺血性脑梗死患者75例的临床资料,收治时间2021年3月-12月,所有患者均接受MRI检查,并行血管造影检查,临床资料完整,诊断以血管造影检查结果为金标准,评价MRI对该组患者诊断的感敏性及准确性。结果 本组75例疑似急性缺血性脑梗死患者,经血管造影检查共检出70例阳性,其中超急性期20例,急性早期35例,急性晚期15例,以此为金标准,MRI对急性缺血性脑梗死的敏感性为93.85%,准确性为82.67%,MRI在超急性期的阳性检出率为90.00%(18/20),在急性早期的检出率为94.28%(33/35),在急性晚期的检出率为93.33%(14/15)。结论 在疑似急性缺血性脑梗死患者诊断中,MRI对疾病诊断的敏感性和准确性较高,能够对病灶情况予以清晰呈现,从而为患者的治疗提供重要依据,临床价值高,值得推广应用。

Abstract

Objective: To observe the sensitivity and accuracy of MRI in the diagnosis of suspected patients with acute ischemic cerebral infarction.
Methods: collected in our hospital were suspected of the clinical data of 75 cases of patients with acute, ischemic cerebral infarction, treated time in March, 2021 - December, all patients were examined by MRI, parallel angiography, complete clinical data, diagnostic angiography results as the gold standard, evaluation of MRI diagnosis in patients with the group of the sensitivity and accuracy.
Results: In this group of 75 suspected patients with acute ischemic cerebral infarction, 70 cases were positive by angiography, including 20 cases in the hyperacute stage, 35 cases in the early acute stage and 15 cases in the late acute stage. Using this as the gold standard, the sensitivity and accuracy of MRI for acute ischemic cerebral infarction were 93.85% and 82.67%, respectively. The positive detection rate of MRI was 90.00% (18/20) in hyperacute stage, 94.28% (33/35) in early acute stage, and 93.33% (14/15) in late acute stage.
Conclusion  : IN the diagnosis of patients with suspected acute ischemic cerebral infarction, MRI has high sensitivity and accuracy in disease diagnosis and can clearly present the lesions, thus providing important basis for the treatment of patients, with high clinical value and worthy of popularization and application.
