摘要:
目的：探讨磁共振成像（MRI）DWI联合3D-ASL对急性脑梗死（ACI）的诊断效能及在血流动力学评估中的应用价值。方法：收集因ACI就诊的80例患者的临床资料，全部入选者均接受1.5T/3.0T MRI进行扫描，分别分析患者脑梗死的DWI、3D-ASL图像表现，并评估DWI联合3D-ASL检查ACI是否具有更高的诊断价值。结果：有49例ACI患者在DWI图像上显示为弥散受限，面积为（673±319） mm2，68例患者在3D-ASL图像上显示为低灌注，低灌注面积为（1 953±803） mm2，其中面积ASL>面积DWI的患者有62例，存在缺血半暗带。在DWI图像上显示为弥散受限的患者中，左侧高信号者的CBF绝对值均低于右侧（22.34±4.36 vs 40.58±9.01, P<0.001），右侧高信号者的CBF绝对值均低于左侧（19.48±5.67 vs 46.01±11.15, P<0.001）。DWI联合3D-ASL检查诊断ACI的灵敏度、特异度、阳性预测值和阴性预测值均高于单独DWI检查。结论：DWI联合3D-ASL检查评估ACI中梗死灶和缺血半暗带具有很大的应用价值。
Abstract:
Abstract: Objective To investigate the efficacy of magnetic resonance imaging (MRI) diffusion-weighted imaging (DWI) combined with 3D-arterial spin labeling (3D-ASL) in the diagnosis of acute cerebral infarction (ACI) and its application value in hemodynamic assessment. Methods Eighty cases of ACI were analyzed. All patients were examined with 1.5T/3.0T MRI. The DWI and 3D-ASL image findings of patients with cerebral infarction were analyzed, and the diagnostic value of DWI combined with 3D-ASL for cerebral infarction was evaluated. Results Out of 80 ACI patients, 49 patients had diffusion limitation on DWI images, with an average area of (673±319) mm2 and 3D-ASL hypoperfusion was found in 68 patients, with an average hypoperfusion area of (1 953± 803) mm2. Ischemic penumbra existed in 62 patients who had larger areaASL than areaDWI. In patients with diffusion limitation on DWI images, the absolute value of CBF of the left-sided hyperintensity was lower than that of the right-sided (22.34±4.36 vs 40.58±9.01, P<0.001), and the absolute value of CBF of the right-sided hyperintensity was lower than that of the left-sided (19.48±5.67 vs 46.01±11.15, P<0.001). Compared with DWI alone, DWI combined with 3D-ASL had higher sensitivity, specificity, positive predictive value and negative predictive value in the diagnosis of ACI. Conclusion DWI combined with 3D-ASL has significant application value in the evaluation of infarct focus and ischemic penumbra in ACI.
