Cardiography half does not contrast if it is caused by a blockage or vascular lesion. If there is an abnormality in the injection or flow of the contrast medium in the body, another examination is needed.
The contrast test involves injecting a contrast agent into a blood vessel, and by observing the flow of the contrast agent and the extent of the flow, the patency of the blood vessel at the test site can be effectively determined. If the result of half of the cardiac contrast does not show the accurate result, then it is necessary to consider the local cardiovascular situation of complete solid change or complete obstruction, and should be timely for surgery or intervention.
As there are many factors that affect the flow of contrast medium. Therefore, inaccuracies in the method of contrast injection or in the amount of contrast injected may also lead to nonenhancement of the test site. If a cardiographic opacity does not lead to a diagnosis of vascular disease, an error in the examination should be considered and a second examination should be performed.
In the event of a cardiographic opacity, a physician should be consulted to determine the cause of the opacity so that appropriate treatment can be carried out.
