The cost of magnetic resonance angiography is between 3,000 and 5,000 yuan, depending on the region, and it is recommended to go to a local tertiary hospital for specific treatment. Magnetic resonance, also known as MRI, is the principle of imaging using atomic nuclei with a non-even number of protons and neutrons, which are deflected in a magnetic field, and in human imaging using water molecules, which are imaged by processing the change in energy before and after MRI. Simply put, the principle of angiography imaging is to use the difference in density caused by the contrast agent in the tissue to image. Magnetic resonance, on the other hand, uses the distribution of water molecules in the tissue to image. There is a fundamental difference between the two. Effectively, MRI imaging is clearer and does not damage the tissue, but there are more restrictions in operation, such as not bringing metal objects into the MRI room, especially when the human body mainly has things like pacemakers, which are not allowed for MRI examinations.
