Adds the event plus preparation reminders at two weeks, one week, two days, and the day before.
Overview
An MRI uses a strong magnet — no radiation — to produce detailed images. The two things that matter: tell them about any metal, and be prepared to hold still in a loud tube.
What to expect
- A screening form about metal, implants, and devices
- Changing into a gown and removing all metal
- Loud knocking sounds; earplugs or headphones are provided
- 20 to 60 minutes of holding still
- Contrast through an IV for some scans
Questions to ask
Is contrast needed, and why?
How long will I be in the scanner?
Who reads the scan, and when will I hear?
In plain language, what is happening and why is it recommended now?
Plain language is your right. Ask again if the answer is technical.
What are my options, including waiting or doing nothing?
How will this change what I can do day to day, and for how long?
What should I do to prepare?
Who do I call with questions, and what number do I use after hours?
What would make you want to see me sooner?
This turns vague worry into a clear trigger for calling.
