Many people go to the Japanese physical examination, will see a physical examination program called head vascular nuclear magnetic **** vibration MRA, for these strange medical terms, compared to many people are not clear, today to give you a detailed introduction to the MRA is mainly used to check what.
One, MRA in the end is what?
Cranial MRA is to take a picture of the cerebral blood vessels, is to use the nuclear magnetic **** vibration machine as a camera into a phase of a special examination, is a special cerebral angiography. Its purpose is to enable the doctor to know clearly the patient's cerebrovascular condition, so that the cerebrovascular lesions at a glance.
Two, MRA check what? What is it for?
MRA examination principle: the use of magnetic field imaging principle of medical imaging diagnostic method, no radiation, very safe, is currently the mainstream of the elderly physical examination program.
Used to check for: the presence of asymptomatic cerebral infarction, cerebral aneurysm, cerebral atrophy, cerebral vascular stenosis, malformations and lesions, and other early stroke risks.
III. Who is it for?

Cycle of physical examination: If there is no cerebral aneurysm in the first examination, it is recommended to be examined once every 3 years.
MRA not only provides vascular morphology signals, but also provides quantitative information such as the direction of blood flow, fringe, and flow rate. Compared with DSA, it has the advantages of being non-invasive, low cost, and generally does not require contrast.
