At present, 1.5T MRI is mostly used for MR scanning of the brain, which costs about$651, plus the cost of angiography is about$968; if 3.0T MRI is used for MR scanning of the brain, it costs about$827, and if enhancement scanning is carried out, it is necessary to pay for the cost of medicines additionally. Because the medical insurance policy is changing rapidly, and the prices of hospitals at different levels are different, it is for reference only. MR examination is not ionizing radiation and the contrast agent is relatively safe and harmless to the human body, so it can be used to examine the nervous system of both adults and children. There are no special precautions for brain MR examination, but other parts of the body may be contraindicated.
