7 Things You Should Know About MRI Scans and Fatigue – ER of MESQUITE
Magnetic Resonance Imaging (MRI) is one of the most common medical tests used to create detailed pictures of the body. It is safe, painless, and does not use harmful radiation like X-rays. However, many patients wonder: can MRI make you tired? This is an important question because feeling drained after medical procedures can cause anxiety.
In this article, we will explore why some people feel tired after an MRI, the science behind it, ways to manage fatigue, and when you should visit ER OF MESQUITE if you are concerned about your symptoms.
What is an MRI Scan?
MRI (Magnetic Resonance Imaging) is a powerful test that uses magnetic fields and radio waves to create clear images of the inside of your body. Doctors often recommend it for:
-
Brain and spinal cord issues
-
Joint and bone injuries
-
Tumor detection
-
Heart and blood vessel conditions
-
Internal organ problems
Unlike CT scans or X-rays, MRIs don’t use ionizing radiation, making them safer for repeated use.
Why Do Some People Feel Tired After an MRI?
Feeling tired after an MRI is not uncommon, but the scan itself does not directly cause fatigue. Instead, tiredness may result from:
-
Stress and Anxiety: Worrying about the scan or results can mentally exhaust you.
-
Claustrophobia: Being in a confined tube can be uncomfortable for some.
-
Noise: Loud banging sounds during the test may disturb your comfort.
-
Sedation or Contrast Dye: Some patients are given medication or dye that can lead to drowsiness.
-
Long Duration: Some MRIs take 30–90 minutes, which can feel draining.
Factors That Increase Fatigue After MRI
Several factors can make you more likely to feel tired after the procedure:
-
Pre-existing medical conditions
-
Lack of sleep before the scan
-
Anxiety about results
-
Use of sedation or anesthesia
-
Fasting before the test (in some cases)
Is the Fatigue Dangerous?
In most cases, fatigue after an MRI is temporary and harmless. You may just need rest, food, and hydration. However, if you also experience:
-
Dizziness
-
Shortness of breath
-
Severe headache
-
Rash or itching (possible allergic reaction to contrast dye)
-
Chest pain
You should visit ER OF MESQUITE immediately to rule out any complications.
How to Reduce Tiredness After an MRI
Here are some simple ways to manage post-MRI fatigue:
-
Stay Hydrated: Drink water to flush out contrast dye.
-
Eat a Balanced Meal: Energy-rich foods help restore strength.
-
Rest: Take it easy for the rest of the day.
-
Manage Stress: Deep breathing and relaxation techniques can help.
-
Bring Support: If you’re anxious, having someone with you can ease the experience.
Can MRI Contrast Dye Cause Fatigue?
Sometimes, contrast dye (gadolinium) is used to highlight certain tissues. While generally safe, it can cause mild side effects such as:
-
Nausea
-
Headache
-
Fatigue
-
Dizziness
Most symptoms disappear within a few hours. Drinking water helps speed recovery.
MRI vs. CT Scan: Which Causes More Fatigue?
-
MRI: Fatigue is usually due to stress or dye, not the scan itself.
-
CT Scan: Faster but involves radiation; fatigue is less common but can occur from contrast dye.
Overall, MRI fatigue is psychological and temporary, while CT rarely causes tiredness.

-
