Abstract:
Objective To investigate the minimum dose of contrast medium when using spectral CT in cranial CTA. Methods Three groups of patients were required to undergo head CTA examination because of their condition,but different doses of contrast agents were injected.Among them,group 30 mL, group B, group 40mL, group C and group 50 mL were A. Results In group A,the lowest rate of excellent image (23.33%), B group, C group had higher rate of excellent image (93.33%, 96.67%), comparison of the data P<0.05; C group the highest rate of adverse reaction of contrast agent (P<0.05),data comparison P<0.05, A group, B group significantly adverse reactions of contrast agent there is no difference between the situation (P>0.05). Conclusion The use of 40 mL iodide contrast medium in the procedure of cranial CTA examination is effective and safe.
