What is the difference between echocardiography and color Doppler echocardiography

Echocardiography and echocardiography differences generally include different detection content, different display methods, different application scopes, etc. 1. Different detection content Echocardiography mainly observes and evaluates cardiac structure and function through ultrasound, including cardiac chamber size, myocardial systolic and diastolic function, cardiac valve movement, etc. Cardiac color Doppler ultrasound is based on echocardiography, through the Doppler effect to show the speed and direction of blood flow, can assess the heart's blood flow, including blood flow velocity, blood reflux and heart valve function, etc. 2. Different display methods Echocardiography is mainly displayed in the form of two-dimensional images. In addition to two-dimensional images, color Doppler ultrasound can also express blood flow with different velocities and directions through color coding, so that the direction and velocity of blood flow can be more intuitively presented, and the shape and contraction process of each part of the heart can be clearly observed. 3. Different application ranges Echocardiography is widely used to evaluate heart structure, function and heart valve diseases, etc. It can be used to detect heart diseases such as cardiomyopathy, myocardial ischemia and pericardial diseases. Cardiac color Doppler ultrasound is mainly used to evaluate cardiac blood flow, and can detect abnormal blood circulation such as heart valve regurgitation, ventricular septal defect and atrial septal defect.
