摘要
目的:探讨不同浓度碘类CT对比剂在腹部疾病检查中的强化效果。方法:将248例行腹部CT扫描的患者分为A、B 2组,使用的对比剂为欧乃派克。A组浓度为300mgI/ml,B组浓度为350 mgI/ml。测量动脉期肾动脉分叉水平腹主动脉强化的CT值,评估2组的强化效果。结果:A、B 2组腹主动脉的强化程度差异有统计学意义(P<0.05)。2种浓度对比剂的强化效果差异无统计学意义(P>0.05),对诊断无影响。结论:350 mgI/ml对比剂对血管的强化程度明显优于300 mgI/ml对比剂,但对组织器官的强化效果无差别,完全可以满足诊断需求。
Objective: To compare the contrast effect with different concentration iodine media on abdominal diseases. Methods: Two hundred and eighty six patientswere divided into two groups. The media was Omnipaque, which concentration was 300 mgI/ml in group A and 350 mgI/ml in group B. Contrast enhancement (HU) of aortal at renal artery level was measured. The contrast effect of two groups was evaluated. Results: There were significant statistical differences on contrast enhancement (HU) between the two groups ( P d0.05), but no significant statistical difference on the contrast effect ( P 〉0.05), which had no effect on diagnosis. Con- clusion: The contrast enhancement in vessels of high concentration media (350mgI/ml) was much greater than that of the low (300mgI/ml), but the contrast effect had no difference in different tissues and organs, which can satisfy the diagnosis completely
