The Clinical Significance of DSA and MRA Detection in Cerebrovascular Disease of Patients with Diabetes Mellitus

Objective To explore the clinical significance of DSA and MRA detection in cerebrovascular desease of patients with diabetes mellitus.Methods 142 diabetic patients were selected in the study. The vascular structure was detected by digital subtraction angiography(DSA) and magnetic resonance angiography(MRA).Results There was 1123(56.5%) branches of artery atherosclerotic stenosis in a total of 1988 detecting artery and there was no significant difference between the DSA and MRA(χ2=0.36、0.47、0.53,P 0.05). The results showed that the DSA and MRA methods had no significant difference on display average count in detecting bilateral ACA,MCA,PCA 284 vessels(t=0.27、0.56、0.89,P0.05). There were 656 arteries stenosis in checking the Willis ring vascular by DSA evaluation of the Willis ring and the sensitivity and specificity by MRA were more than 90%. Conclusion MRA and DSA can be applied in diagnosis of in cerebrovascular disease of patients with diabetes mellitus.The noninvasive advantages of MRA are worth to be concerned by clinician.
