The charge of head MRI ranges from about 500-3000 RMB, and there are more reasons affecting the price of head MRI, mainly including magnetic resonance items, magnetic resonance field strength, magnetic resonance examination organization and so on. 1. Magnetic resonance project: Head magnetic resonance examination project is more, including head scanning, head enhancement scanning, vascular imaging, brain function imaging and so on. The total cost of the test varies depending on the test items required by the individual. Usually, the more items needed, the higher the fee. 2. MRI field strength: There are different field strengths of MRI instruments, mainly including 0.5t, 1.5t, 3.0t. Among them, 3.0t MRI has a higher resolution, and its charges will also be increased. 3. Magnetic resonance examination organization: The precision and accuracy of magnetic resonance examination is constrained by the technical level of magnetic resonance instruments and operators. Usually, the charges of high-grade facilities are higher than those of low-grade facilities. For head MRI examination, people with metal implants, pacemakers, tattoos, dentures and other metal substances should inform the doctor before the examination to avoid carrying metal items and electronic products, so as to avoid interfering with the magnetic field, thus affecting the accuracy of the examination.
