The Effects of Different Injection Rates of DS A Contrast Agents on Image Quality and Safety of Intracranial Vascular Diseases
Objective:To investigate the effects of different injection rates of DSA contrast agent on the image quality and safety of intracranial vascular diseases.Methods:A total of 150 patients with intracranial vascular disease were selected by 2022.1-2023.12,divided into three groups A,B and C,with 50 patients in each group.The injection rate was 1.5 mL/s in group A,3 mL/s in group B and 5 mL/s in group C,with DSA contrast comparing the three image indexes and serum creatinine values before and after contrast.Results:The contrast dosage was group A<B<C,P<0.05;compared with groups B and C,CNR,eye and middle cerebral artery were lower,P<0.05;B and C,P>0.05.Before and after contrast,the comparison of serum creatinine values in the three groups was not statistically significant,P>0.05.Conclusion:The injection rate of 3 mUs contrast agent can improve the image quality of intracranial vascular disease of DSA,and does not significantly increase the serum creatinine level of patients.
