摘要

在阿根廷和全世界,中风或脑血管发作是致残的第一大原因和死亡的第三大原因。中风的病因多为缺血性(80%以上),最常见的原因是小血管腔隙型缺血性病变和大动脉粥样硬化或心脏栓塞引起的血栓栓塞性病变。在我们的研究方案中使用的序列包括DWI、FLAIR、angio-RM 3D-TOF、SWI和FSE-T1(大约扫描时间为13分钟)。在这些序列中可以观察到不同的结果,这些结果对确定潜在的病因和估计病变的演变时间具有指示性。目前,机械取栓已成为部分急性缺血性脑卒中患者的首选治疗方法。出血转化是动脉再灌注治疗后最可怕的并发症。弥散磁共振技术对缺血性病变的检测更敏感,可以根据病变模式怀疑病因,并为选择动脉再灌注候选者提供有价值的信息。

Utilidad de la resonancia magnética en el diagnóstico del stroke agudo
Stroke or cerebrovascular attack (CVA) is the first cause of disability and the third cause of death in Argentina and in the world. The etiology of strokes is mostly ischemic (more than 80% of cases), with the most frequent causes being lacunar-ty-pe ischemic lesions of small vessels and thromboembolic lesions due to atherosclerosis of large arteries or cardioembolism. The sequences used in our study protocol include DWI, FLAIR, angio-RM 3D-TOF, SWI, and FSE-T1 (approximate scan time of 13 minutes). Different findings can be observed in each of these sequences that are indicative to determine the underlying etiology and estimate the time of evolution of the lesion. Currently, mechanical thrombectomy has become the treatment of choice in selected patients with acute ischemic stroke. Hemorrhagic transformation is the most feared complication after intra-arterial reperfusion therapy. The diffusion magnetic resonance technique is more sensitive for detecting ischemic lesions, allows one to suspect the etiology based on the lesion pattern, and provides valuable information for the selection of patients who are candidates for arterial reperfusion.
