MRI Safety Overview
How MRI works, why screening matters, and what we do to keep every patient safe inside the scanner.
MRI With Implants & Devices
Pacemakers, neurostimulators, cochlear implants, joint replacements, IUDs, and more — what's safe and what we need to know.
Tattoos, Piercings & Makeup
Why tattoo ink can warm up in the magnet, which piercings need to come out, and how permanent makeup is handled.
Contrast Dye Overview
What imaging contrast is, why it's used, how safe it is, and when to tell us about allergies or kidney problems.
Gadolinium Contrast (MRI)
How MRI contrast is used, who should not receive it, and what side effects are typical.
Iodine Contrast (CT)
How CT contrast works, who needs premedication, and what we do for patients with allergies or kidney concerns.
Radiation Dose & Safety
Which scans use radiation and which don't, what "dose" really means, everyday comparisons, and how we keep your exposure as low as possible.
CT Radiation Dose & ALARA
How much radiation a CT scan actually delivers, how we keep dose as low as reasonably achievable, and what to discuss with your provider.
Claustrophobia & MRI
Wide-bore scanners, music and video, oral anti-anxiety options, and other strategies that get patients through their MRI.
Pregnancy & Imaging
What's generally considered safe during pregnancy, when radiation and contrast need extra thought, and why telling us matters most.
Pediatric Imaging
How we keep children comfortable, the child-sized dose adjustments we use, and how parents can prepare a child for a scan.
