Magnetic resonance imaging (MRI scan) is taken into account one of many most secure and most detailed imaging assessments out there right now. Not like X-rays and CT scans, it doesn’t use radiation and is due to this fact appropriate for diagnosing situations involving the mind, backbone, joints, nerves, and inside organs.
However regardless of its widespread use, the security of MRI continues to confuse many individuals, particularly these with metallic implants, pacemakers, tattoos, or medical situations corresponding to being pregnant or kidney illness.
In line with Dr. Atampreet Singh, senior director and head of neuroscience at ShardaCare-Healthcity, MRI is protected for most individuals, however there are specific conditions that require particular precautions.

Who ought to keep away from MRI scans?

Nevertheless, your physician will rigorously think about the kind of implant, when it was positioned, and any security precautions earlier than permitting the scan.
“To keep away from potential dangers, sufferers ought to at all times inform the MRI crew about any implants, surgical procedures, or metallic devices within the physique,” urges neurologists.
Is MRI protected throughout being pregnant?
Being pregnant is one other space the place many sufferers have considerations about MRI scans.
Dr. Singh explains that MRI throughout being pregnant is mostly thought of protected as a result of MRI doesn’t expose the physique to dangerous radiation. Nevertheless, docs are normally extra cautious through the first trimester and will keep away from an MRI until it’s medically essential.
