- W2385077477 abstract "Objective To discuss the application of low tube voltage scan protocol in performing coronary angiography with 64-row spiral CT scanning in order to reduce the contrast medium dosage. Methods A total of 54 patients with 18. 0 BMI≤22. 0 were randomly divided into group A( control group,n = 10),group B( low contrast medium dosage group, n = 22) and group C( low tube voltage combined low contrast medium dosage group,n = 22). In group A,tube voltage of120 kVp,tube current of 600 mA,contrast medium dosage of 65 ml together with 40ml saline and injection flow rate of 5.0 ml /s were use for CT coronary angiography. In group B,same tube voltage and tube current as in group A,contrast medium dosage of 0. 7 ml /Kg together with 30ml saline and injection flow rate of 4. 5 ml /s were adopted for CT coronary angiography. In group C,tube voltage of 80 kVp,tube current of 600 mA,and the same contrast medium dosage,saline and injection flow rate as in group B were employed. The results were analyzed. Results The contrast medium dosage,attenuation values of ascending aorta,image noise,radiation dose index,and effective radiation dosage were determined. The differences between each other among the three groups were statistically significant( F = 420. 16,F = 97. 51,F = 76. 98,F= 305. 91 and F = 324. 21 respectively,P 0. 01 in all). In group C the used contrast medium dosage reduced by43. 35% and the radiation dose reduced by 65. 83% when compared with those in group A. The peak value of attenuation of aorta was increased by 81. 17% in group C when compared with that in group B. The differences in image quality scores were statistically significant between each other among the three groups( χ2= 8. 29,P 0. 05). Image quality score of group C was higher than that of group B. Conclusion In performing coronary angiography with 64-row spiral CT,low tube voltage scan protocol combined with reasonable low dosage of contrast medium can not only significantly reduce the radiation dosage,but can also increase the aorta attenuation and improve image quality as well." @default.
