What is the difference between heart color Doppler ultrasound and cardiac ct and cardiography?

Cardiac CT refers to cardiac CT examination. The difference between cardiac ultrasound and cardiac CT examination and cardiac angiography lies in the different diseases investigated, different principles and different examination items.

1. The

diseases examined by different cardiac ultrasound are mainly congenital heart disease, cardiomyopathy, heart valve disease and other diseases. Cardiac CT examination is mainly used for the initial screening of coronary atherosclerotic heart disease. Cardiac imaging can be used to detect acute myocardial infarction, heart failure, heart tumors and other diseases.

2. Different principles Cardiac

ultrasound is mainly used to observe the pulse of the heart and blood flow. Cardiac CT examination is to examine the shape and structure of the heart through computed tomography. Cardiac imaging is to observe coronary arteries, heart valves, etc. under X-ray or ultrasound through the distribution of contrast media, to determine whether there is thrombus, tumor, etc.

3. Examination items Different

cardiac ultrasound examination items include two-dimensional ultrasound, color Doppler ultrasound, etc. Cardiac CT examination items are divided into cardiac CT plain scan and cardiac enhanced CT. Cardiography includes coronary angiography and ventriculography.
