Abstract:
Objective To discuss the consequences of CT image quality in two different contrast enhancement ways of high pressure syringe. Methods 100 cases by using high-pressure syringes of Lightspeed 16-raw spiral CT and Stellant D-type high-pressure syringe of Medrad, the dose of constrast medium was 4.0 ml/s and the total dose was 80 ml, which was divided into A and B group enhancement scanning. The canalis singularis high pressure syringe was used in 50 cases of A group that no isotonic Na chloride flush, in contrast to 50 samples of B group that were underwent the double isotonic Na chloride flush. The method of evaluation is double-blind observation. Results The number of positive is 40 samples which has radioactive constructed defect in A group. The masculine proportion is 80%. The number of the negative is 10 samples. The proportion is 20%. Correspondingly, the number of radioactive constructed defect in the B group is 24 samples(48%), and the negative number is 26 samples(52%, P
