以给药时间为中心的先天性心脏病CT扫描方案
Administration-Time-Centered Congenital Heart Disease CT Scanning Plan
摘要
Abstract
Objective:To seek a congenital heart disease(CHD)CTA scanning plan combining with image quality and operability on the basis of administrating time.Method:Scans were performed on 55 CHD patients through three groups,including dynamic monitoring method group of 19 patients,visual with manual triggering method group of 18 patients,and administration-time-centered method group of 18 patients,then beam hardening artifact score and ventricular cavity’s contrast media concentration among the above mentioned three ways were evaluated.Result:The beam hardening artifact score in the administration-time-centered method was better than that of both dynamic monitoring group and visual with manual triggering group.With respect to contrast media concentration of right ventricular cavity,the figures in the administration-time-centered group was lower than that in the dynamic monitoring group and visual&manual triggering group.While the figures in the concentration of left ventricular cavity in the administration-time-centered group were higher than that in the visual with manual triggering group but showed no statistical difference compared with the figures in the dynamic monitoring group. Conclusion:Administration-time-centered method integrates parameters such as performance of machine,speed of drug administration,and scanning time into account,adopts formula to quantize scan triggering time,and makes CHD CT scanning more easily to be grasped.In addition,its restriction on beam hardening artifact is superior to traditional plan,therefore this method can be further studied and applied in clinical field.关键词
