Application of Non-breathholding Photography Technology in Angiography / 医疗卫生装备

ABSTRACT

Objective To explore the application of non-breathholding photography technology in angiography. Methods 183 cases with abdominal and thoracic DSA examination were separated into non-breathholding experimental group and conventional breath-hold control group in proper order. The experimental group collected images in natural breathing and the conventional group gained images after inspiratory breathholding in imaging process. The images of two groups were adjusted by the post-processing functions and were print film; the quality of the images was evaluated. Results In the chest experimental group(n =37) had 36cases(97.30% )satisfactory and 1 case(2.70% ) unsatisfactory, and the control group(n=36)had 32cases(88.89%) satisfactory and 4 (11.11%) unsatisfactory. In the abdominal experimental group(n=55) had 53 cases(96.36%) satisfactory and 2 cases(3.64%) unsatisfactory images, and the control group(n=55) had 49 cases(89.09%) satisfactory and 6cases(10.91%) unsatisfactory images. There is no significant difference of the image quality between the two groups in each part (chest part ?2=2.02, 0.1
