After your MRI scan is complete, you can usually return to your normal routine right away. An MRI is a safe and non-invasive imaging test, and most people do not need any special care afterward. However, there are a few simple steps you should follow, especially if you received contrast dye or sedation.
This guide explains what to do after an MRI scan and when to contact your doctor.
1. Return to Your Normal Activities
For most routine MRI scans (without sedation), you can return to your usual daily activities immediately upon leaving the imaging clinic.
You can normally:
- Return to work or school
- Drive yourself home safely
- Eat your regular meals
- Exercise as usual (unless your doctor advised restriction due to an injury)
If your doctor has given you specific medical instructions, follow them carefully.
2. Drink Plenty of Water (After Contrast Dye)
If you received a gadolinium-based contrast dye during your MRI, drinking extra water is strongly recommended.
Staying well-hydrated helps your kidneys process and eliminate the contrast dye naturally through your urine within 24 hours. Unless your physician has placed you on strict fluid restrictions, aim for 6–8 glasses of water throughout the rest of the day.
3. Eat Normally
If you were asked to fast for a few hours before your scan, you can enjoy food and drink immediately once the test is finished. Starting with a light, balanced meal is recommended if you have an empty stomach.
4. Watch for Unusual Symptoms
The vast majority of patients feel completely normal after an MRI. However, if you received contrast dye, monitor yourself for rare allergic reactions:
- Skin rash, hives, or intense itching
- Difficulty breathing or wheezing
- Swelling around the face, throat, or IV injection site
- Severe headache or persistent dizziness
These reactions are very uncommon, but if they occur, seek immediate medical attention or notify the imaging clinic.
5. Follow Instructions After Sedation
If you were given oral or IV sedative medication to manage anxiety or claustrophobia:
- Do not drive or operate machinery for 24 hours.
- Have a responsible family member or friend escort you home.
- Rest quietly at home for the remainder of the day.
- Avoid alcohol and refrain from signing legal documents until the medication fully wears off.
6. Wait for Your MRI Results
Once your scan is saved, a specialized radiologist meticulously examines the hundreds of cross-sectional images and writes a comprehensive diagnostic report. The final report and digital films are usually sent directly to your referring doctor within 24 to 48 hours.
7. Contact Your Doctor for Next Steps
Your referring physician will interpret the MRI findings in the context of your symptoms and medical history. They will explain:
- What the MRI scan revealed
- Whether any follow-up tests or repeat imaging are indicated
- Appropriate medical or physical therapy treatments
