A special doctor called a radiologist analyzes the MRI images. Frequently, the chest MRI will help to better evaluate diseases of the heart, lung and chest wall. Chest MRIs can reveal the size and location of tumors, blood vessel abnormalities, heart problems, hemorrhages and other tissue abnormalities. This technique is useful in studying disorders of the ribs and sternum. The person's healthcare provider and the radiologist will use this information to help guide the treatment plan for the individual's condition.
