摘　　要：目的探讨在颅脑磁共振成像(MRI)增强扫描中应用不同剂量造影剂,对颅脑病灶强化率的影响。方法72例接受颅脑MRI增强扫描检查的患者,根据造影剂应用剂量不同分为甲组(25例)、乙组(25例)、丙组(22例)。甲组患者应用0.10 ml/kg造影剂,乙组患者应用0.20 ml/kg造影剂,丙组患者应用0.40 ml/kg造影剂。比较三组颅脑病灶强化情况。结果乙组总强化率92.0%高于甲组的68.0%,差异有统计学意义(P<0.05)。丙组总强化率100.0%高于甲组的68.0%,差异有统计学意义(P<0.05)。乙组与丙组总强化率比较,差异无统计学意义(P>0.05)。结论通过以0.20 ml/kg的造影剂实施检查,能够使得接受颅脑MRI增强扫描患者得到较高强化率,符合临床诊断要求的同时,还能够起到节约成本的作用,适宜深入研究与推广。Objective To investigate the effect of different doses of contrast agents in cranial magnetic resonance imaging(MRI)enhancement scans on the enhancement rate of cranial lesions.Methods A total of 72 patients who underwent contrast-enhanced cranial MRI were divided into group A(25 patients),group B(25 patients),and group C(22 patients)according to the dose of contrast agent applied.Patients in group A applied 0.10 ml/kg of contrast agent,patients in group B applied 0.20 ml/kg of contrast agent,and patients in group C applied 0.40 ml/kg of contrast agent.The enhancement of cranial lesions in the three groups was compared.Results The total enhancement rate in group B was 92.0%,which was higher than that of 68.0%in group A,and the difference was statistically significant(P<0.05).The total enhancement rate in group C was 100.0%,which was higher than that of 68.0%in group A,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the total enhancement rate between group B and group C(P>0.05).Conclusion The use of 0.20 ml/kg of contrast agent enables patients receiving cranial MRI-enhanced scans to obtain a high rate of enhancement,which meets the clinical diagnostic requirements,and can also play the role of cost saving,which is suitable for further research and promotion.
