探讨使用CT对比剂在肺循环动静脉中峰值 时间差值评价慢性心衰的可行性
Peak-Time Interval of CT Contrast Medium Between Pulmonary Artery and Vein: An Objective and Quantified Indicator for Chronic Heart Failure
摘要
Abstract
Objective To study the feasibility of CT TestBolus in achieving of peak-time interval of CT contrast medium between pulmonary artery and vein as an Objective indicator for chronic heart failure. Methods We retrospectively collected 60 patients, who need to clndergo CT scan with contrast medium. They were divided into two groups (control group with normal heart and test group with chronic heart failure). CT TestBolus was applied to both groups. Then the acquired attenuation time curve was analyzed by DynEva and the peak-time interval of contrast medium between pulmonary artery and vein (ΔTp) were calculated. The relationship between left ventricular ejection fraction (LVEF) of B ultrasonic andΔTp was evaluated by using pairedt tests.Results TheΔTp and LVEF in the test group were significantly changed, and there were significant differences between the control group and the test group.Conclusion ΔTp acquired by CT TestBolus is of great value in evaluation of chronic heart failure, which can be used in assessing of severity for chronic cardiac failure.关键词
