Value of Ultrasonic Cardiogram Combined with Flash CT in Diagnosis of Conotruncal Defects
The paper aims at exploring the value of ultrasonic cardiogram (UCG) combined with Flash CT in the diagnosis of conotruncal defects (CTD). This complex cyanotic congenital heart disease is divided into several types by using UCG and Flash dual source CT imaging. The results show that the detection method of UCG is simple and fast, but it has some deficiencies in the display of extracardiac vessels. Flash CT technology has a strong image post-processing function, which makes up for the shortcomings of UCG and is an important supplementary means for patients after echocardiographic examination. Therefore, UCG combined with Flash CT technology can detect the patient's disease more accurately and quickly, avoid the traumatic detection of angiography, and is more convenient. It is hopeful to replace angiography as the gold standard for the diagnosis of congenital heart disease.
