Cardiac MRI typically lasts between 30 and 90 minutes. This highlights the blood vessels or heart in the pictures.
Sometimes, a contrast agent is used – injected into a vein in the arm through a needle. The technician will control the machine from the next room and will be able to communicate with you through a microphone. The patient will be asked to lie on their back on a sliding table and asked to stay as still as possible. It also prevents the MRI machine's strong magnetic fields from disrupting other equipment. The MRI machine will be located in a special room that prevents radio waves from disrupting the machine. The patient will be asked to remove any clothing jewelry, or other items that may interfere with the procedure. Patients should know that a cardiac MRI is painless and harmless. What can a patient expect during a cardiac MRI? An MRI is also commonly used to clarify unclear findings from echocardiography. It is used to detect or monitor heart problems such as infections or inflammatory conditions, coronary artery disease, congenital heart disease, or to evaluate the effects of surgery. Vascular Diagnostic TestingĬardiac magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves and a computer to create a clear and concise image of a patient’s heart in motion, without using x-ray radiation. The doctor will then discuss the results with the patient, and use them to create or modify a treatment plan. The patient is encouraged to stop the test at any time if they become too tired or uncomfortable.Īfter a stress test, results will be sent to the patient’s cardiologist. The test continues until the patients hear rate reaches a certain target or feels unable to continue.
As the test progresses, the speed and incline of the treadmill may increase, during which time breathing, heart rate, and blood pressure are all monitored.
When a patient comes in for a stress test they will be hooked up to special equipment used to monitor the heart, and asked to walk on a treadmill. Since exercise requires the heart to work hard and pump blood, the stress test can reveal otherwise unnoticeable problems with the heart or be used as a guide to further treatment if there has already been a diagnosis. We offer diagnosis and treatment in over 70 specialties and subspecialties, as well as programs, services, and support to help you stay well throughout your lifetime.Ī stress test is done to gather information about how the heart works during physical activity.
