Your doctor may recommend chest MRI if he or she thinks you have a chest condition, such as:
- A tumor
- Problems in the blood vessels, such as an aneurysm (AN-u-rism) or blood clot
- Abnormal lymph nodes
- Another chest condition, such as a pleural disorder
Researchers are exploring ways to use chest MRI to study blood flow in the lungs. The test may help detect early signs of pulmonary hypertension (PH). PH is increased pressure in the pulmonary arteries. These arteries carry blood from your heart to your lungs to pick up oxygen.
