c)    Those who have implanted metal substances in the body, such as: steel nails, heart rhythm regulators, artificial heart valves, cochlear implants, internal electrodes, nerve stimulators, drug injectors implanted in the body, vascular stents, magnetic prostheses, magnetic prostheses, metal prostheses, metal joints and other important organ metal implants.

4.     Although the magnetic resonance angiography is harmless to the human body, it will emit noise during the scanning process. In order to reduce the noise, the center will provide a pair of personal earplugs for each subject. Before entering the scanning room, the participant must verify of having wear earplugs.

As magnetic resonance image is very sensitive to movement, the quality of the images will be bad if the participant moves the head or body during the scanning process. Therefore, the participant is suggested to remain still during the experiment.
