If the ordinary people understand, the scope of filming is relatively wide, such as X-ray, CT examination and MRI examination belong to the scope of filming. The cost of an ordinary x-ray is 110 yuan, the cost of an ordinary plain CT with low resolution is about 300 yuan, and the cost of a CT with high resolution and 3D reconstruction is much higher. The cost of a 64-row 3D reconstruction CT can reach 800-1000 RMB. The cost of an MRI is also related to the resolution of the machine, and the cost of an ordinary 1.5T MRI is about$500, while the cost of a 3.0T MRI is about$800. Because the cost of each test is not low, so do not decide privately what test is good, each test can not replace each other, each test has its focus, you should let the doctor check the body to clearly determine which test is necessary before doing it.
