- Abstract:
- Abstract: Objective To analyze the clinical value of magnetic resonance imaging (MRI) combined with susceptibility-weighted imaging (SWI) in evaluating the prognosis of acute cerebral infarction. Methods A total of 100 patients with acute cerebral infarction were randomly divided into observation group (n=50) and control group (n=50). Patients in control group underwent MRI, while those in observation group underwent MRI combined with SWI. The detection rates of disease and cerebral microhemorrhage were compared between two groups. Results The detection rates of disease and cerebral microhemorrhage in observation group were significantly higher than those in control group (96.0% vs 78.0%, P<0.05 64.0% vs 12.0%, P<0.05). The bleeding area detected in observation group was (972.83±110.54) mm2, which was significantly larger than (532.71±110.53) mm2 in control group (P<0.05). The diagnostic score of cerebral infarction area in observation group was significantly lower than that in control group (P<0.05). Compared with those in control group, the neurological deficiency score 15 days after admission in observation group was lower (P<0.05), and the stable and improvement rates of neurological deficiency are significantly higher (P<0.05). Conclusion MRI combined with SWI not only has a significantly higher detection rate for acute cerebral infarction, but also can accurately predict cerebral microhemorrhage, which is helpful to formulate correct clinical treatment plan and improve the prognosis of patients with acute cerebral infarction.
