摘要:
目的 探讨分析三向同性扩散加权成像（DWI）、与表观扩散系数图（ADC）在不同时期脑梗塞的诊断以及转归和分期中的应用价值。方法 选择2018年1月-2020年12月我院收治的96例脑梗塞患者，对所有患者进行常规MRI检测、以及DWI检测，并对不同时期脑梗塞患者的病灶面积以及检测准确性等进行比较。结果 急性期与亚急性期DWI脑梗塞患者病灶面积检测值高于MRI，超急性期DWI脑梗塞患者病灶面积检测值高于MRI，差异有统计学意义（P＜0.05）；急性期与亚急性期DWI脑梗塞患者检出率高于MRI，超急性期ADC值、rADC值低于急性期、亚急性期，差异有统计学意义（P＜0.05）；急性期ADC值、rADC值，低于亚急性期，差异有统计学意义（P＜0.05）；超急性期脑梗塞患者在T2WI上无异常信号存在，急性期、以及亚急性期脑梗塞患者T2WI上均有高信号表现存在，DWI上不同时期脑梗塞患者均有高信号表现存在。结论 在不同时期脑梗塞患者的临床诊断中，采取DWI、ADC进行检测诊断，可以有效提高诊断价值；检测患者病灶面积的同时，可以借助ADC具有的特性，提高对患者不同分期诊断价值，有助于临床对治疗效果放入动态观察。
Abstract:
Objective To investigate the value of three-dimensional diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) in the diagnosis, prognosis and staging of cerebral infarction in different periods.Methods A total of 96 patients with cerebral infarction admitted to our hospital from January 2018 to December 2020 were selected. All patients were examined by routine MRI and DWI, and the lesion area and detection accuracy of patients with cerebral infarction in different periods were compared.Results The detection value of lesion area in patients with acute and subacute DWI cerebral infarction was higher than that of MRI, and the detection value of lesion area in patients with ultra-acute DWI cerebral infarction was higher than that of MRI, the difference was statistically significant (P<0.05). The detection rate of DWI cerebral infarction in acute phase and subacute phase was higher than that of MRI, the ADC value and rADC value in super acute phase were lower than those in acute phase and subacute phase, and the difference was statistically significant (P<0.05). ADC value and rADC value in acute phase were lower than those in subacute phase, and the difference was statistically significant (P<0.05). There was no abnormal signal on T2WI in patients with hyperacute cerebral infarction, there was high signal on T2WI in patients with acute and subacute cerebral infarction, there was high signal on DWI in patients with cerebral infarction at different stages.Conclusion DWI and ADC can effectively improve the diagnostic value in the clinical diagnosis of patients with cerebral infarction at different stages. While detecting the lesion area of patients, the diagnostic value of ADC in different stages can be improved by virtue of the characteristics of ADC, which is helpful for the dynamic observation of clinical therapeutic effect.
