Non-invasive imaging techniques generally don't have any surgery to remove tissues, needles, fluids that have to be inserted into the body. The non-invasive imaging process focuses to establish the risk of individuals developing heart disease in the future and also preventing major cardiovascular diseases such as myocardial infarction, stroke. The intensity of the reflected ultrasound image is indicated by grayscale; fluid or blood appears black, and highly reflective structures, such as calcifications on cardiac valves or the pericardium, appear white. Tissues such as myocardium appear grayer, and tissues such as muscle display a unique interference pattern.
