Early Analysis of Acute Cerebral Infarction by Magnetic Resonance Diffusion Weighted Imaging

Abstract

Objective: The mortality and disability rate of cerebral infarction are high. Early diagnosis and early treatment can improve the prognosis of patients. Conventional computed tomography (CT) and magnetic resonance imaging (MRI) is lack of sufficient sensitivity. The purpose of this study was to investigate the effect of MRI diffusion weighted imaging (DWI) in the early analysis of acute cerebral infarction. Methods: Forty patients with acute cerebral infarction admitted to the Second Affiliated Hospital of Anhui Medical University were examined in this study. With the cooperation of nursing staff, the routine MRI scan sequence and DWI was performed. The ADC values were analyzed and compared in different patients. Results: All the patients completed the examination successfully. In conventional MRI, equal signal was found in hyperacute cerebral infarction, while high signal on T2WI was found in 66% of patients with acute cerebral infarction. Both hyperacute and acute cerebral infarction showed the high signal in DWI. Compared with the contralateral normal tissues, the ADC value in cerebral infarction area was significantly decreased, especially in patients with hyperacute cerebral infarction. Conclusions: The nursing cooperation is helpful for the MRI examination. The DWI is more sensitive than conventional MRI in the analysis of acute cerebral infarction and can distinguish the hyperacute and acute stage, thus providing evidence for effective individualized treatment of patients.
