1. Is it noisy?
3.0T magnetic * * * vibration noise is still relatively large, but generally speaking, you will wear headphones when scanning, so it will not have a great impact;
2. Will it cause harm?
Generally speaking, no, all clinical scans must pass the noise safety standards of FDA and sFDA to ensure that it will not cause harm to human ears.
Besides, I'll give you a free suggestion. Before you scan your face, you'd better make sure that all parts of your body are free of metal objects. Otherwise the consequences will be very serious.
