breathing MRI what to expect
Overview
A breathing MRI is a type of magnetic resonance imaging (MRI) scan where you follow specific breathing instructions, like holding your breath or breathing deeply. This helps get clear pictures of your lungs, heart, or diaphragm.
Key facts
- It uses strong magnets and radio waves to create detailed images.
- You may be asked to hold your breath for 10–20 seconds at a time.
- It is painless and involves no radiation.
- You can usually go home the same day.
Breathing MRI scans are becoming more common, especially for lung and heart imaging.
Anyone who needs a detailed look at their chest or abdomen may have this test.

Diagnosis
The breathing MRI is one of the tests used to diagnose conditions affecting the lungs, heart, or chest.
Tests that may be done
- Breathing MRI scan
- Chest X-ray
- CT scan
- Blood tests
What to expect at your appointment
You will lie on a table that slides into a tube-like scanner. A radiographer will give you clear instructions on when to breathe in, out, or hold your breath. The scan takes about 30 to 60 minutes. You can communicate with the radiographer throughout.
Treatment
Treatment will depend on what the MRI shows. Your doctor will discuss the results and recommend a plan.
Self-care at home
- Follow your doctor's advice on managing any underlying condition
- Stay active as much as possible
- Eat a balanced diet
Medical treatments
Depending on the diagnosis, treatments may include medications (such as inhalers or heart medications), physiotherapy, or procedures to improve breathing.
When is surgery considered?
Surgery may be considered for conditions like lung cancer or severe heart valve problems.
Living with this condition
Most people can resume normal activities immediately after the scan.
Lifestyle tips
- Stay hydrated before the scan unless told otherwise
- Wear comfortable clothing without metal
- Inform the radiographer if you are anxious about enclosed spaces
Diet and exercise
No special diet is needed for the scan, but you may be asked to avoid eating for a few hours beforehand if sedation is used. Regular exercise is beneficial for overall lung health.
Mental health and emotional wellbeing
Having an MRI can cause anxiety for some people. Tell your healthcare team if you feel nervous — they can help with relaxation techniques or offer sedation.
Prevention
The conditions that require a breathing MRI are not always preventable, but maintaining a healthy lifestyle can lower your risk.
Vaccines
Vaccinations like the flu shot and pneumonia vaccine may help prevent lung infections.
Screening programmes
Your doctor may recommend regular check-ups depending on your risk factors.
Complications
If left untreated
- If the underlying condition is not addressed, symptoms may worsen over time.
Long-term outlook
Most breathing MRI scans are safe and provide crucial information to help your doctor give you the best care. With proper treatment, many conditions can be managed well.
