What Are the Different Types of Vascular Imaging?

Cardiovascular magnetic resonance imaging (CMR), commonly known as cardiac MRI , is a non-invasive medical imaging technique that evaluates the function and structure of the cardiovascular system. It uses the basic principles of magnetic resonance imaging (MRI) to address the special difficulties of imaging the cardiovascular system, and optimizes existing MRI imaging technology to make it clinically valuable. The emphasis of optimized sequence design is mainly on ECG gating and fast imaging technology. Combining these different technologies, the resulting scheme can evaluate the main functions, morphology, and structure of the cardiovascular system.

CMR imaging principle and other

CMR includes many different technologies. Combining these technologies enables a comprehensive assessment of the heart and vascular system. Examples are as follows:

CMR can play a significant role in the clinical diagnosis of cardiovascular disease. Compared with other medical imaging methods, CMR has the advantages of high imaging quality, non-invasive, accurate, and no ionizing radiation; its disadvantages are high cost, not many places to use, professional operators are needed, and the technology lacks a large number of clinical Clinical outcome. ^[1]

Congenital heart defects are the most common type of birth defects in children, and accurate diagnosis is essential for a correct treatment plan. CMR does not use X-rays and does not penetrate the human body, and provides comprehensive information on the mechanism of congenital heart disease. It is rarely seen as the only detection method for congenital heart disease, and is often used in combination with other technologies. In general: CMR is selected for clinical examination based on the following reasons: 1) when

CMR scanners must be advanced. For cardiac imaging, open magnets are not very suitable because they do not respond well to the effects of heartbeat. Scanners of two magnetic field strengths are now mainly used-1.5T and 3T. The advantage of 3T is its high signal-to-noise ratio, which has special advantages in perfusion imaging. However, the disadvantages of 3T are that it is too expensive and potentially affects image quality artifacts. ^[2]
