Objective To investigate the value of multi-slice spiral CT(MSCT)cerebrovascular imaging and magnetic resonance imaging(MRI)in the diagnosis of cerebrovascular diseases.Methods A retrospective case-control study was conducted to analyze the data of 103 patients with cerebrovascular diseases admitted to our hospital from July 2020 to August 2022.All patients were examined by MSCT cerebrovascular imaging and MRI,with the results of digital subtraction angiography(DSA)as the gold standard.The detection results of DSA in patients with cerebrovascular diseases and the accuracy of MSCT cerebrovascular imaging and MRI in the detection of cerebrovascular diseases.Results Among the one hundrecl and three patients with cerebrovascu-lar diseases,fifty-three,thirty-six,fourteen cases of cerebral infarction,cerebral hemorrhage and cerebral a-neurysm were detected by DSA,respectively.The cases of cerebral infarction,cerebral hemorrhage and cerebral a-neurysm detected by MSCT were 51 cases,33 cases and 11 cases,respectively,with diagnostic accuracy of 94/103(91.26%);the cases of cerebral infarction,cerebral hemorrhage and cerebral aneurysm detected by MRI were 52 cases,35 cases and 14 cases,respectively,with diagnostic accuracy of 101/103(98.05%).The diagnostic accuracy of MRI was higher than that of MSCT.Conclusion Both MSCT cerebrovascular imaging and MRI can diagnose patients with cerebrovascular diseases.Although the diagnostic accuracy of MRI is higher than that of MSCT cerebrovascular imaging,the examination time is longer than that of MSCT cerebrovascular imaging.Therefore,appropriate examination methods should be selected according to the specific conditions in clinical practice.
