Yes. MRI machines use magnets instead of radiation, making them a safer alternative for anyone concerned about the small amounts of radiation used in X-rays and CT scans. If you have any metal implants, like a pacemaker, you should talk to your doctor before receiving an MRI to ensure it’s safe for you. Open MRIs are also safer for people with conditions like COPD, which can make it harder for them to breathe while lying flat in a closed MRI machine.
