That's why early detection is so important. The earlier a problem is detected, the easier it is to treat.
One of the best ways to detect heart problems early is through an MRI scan. In addition, a heart MRI scan can help identify problems with your heart that might not be detectable with other tests.
A cardiac MRI scan is a non-invasive medical imaging procedure that produces high-quality images of the heart and its surrounding structures. The procedure uses a powerful magnetic field and radio waves to create detailed pictures of the heart. Cardiac MRI scans are often used to evaluate the size and function of the heart, and to assess the severity of certain conditions. These include heart attack, congestive heart failure, and cardiomyopathy. The procedure is generally well tolerated, but some people may experience claustrophobia or anxiety due to the confined space inside the MRI machine.
Your doctor may recommend a cardiac MRI if you have symptoms that suggest you may have a heart condition, such as chest pain or shortness of breath. Cardiac MRI may also be recommended if you have been diagnosed with a heart condition and your doctor wants to get more information about the extent of the damage or how well your heart is functioning.
Cardiac MRI is often used to assess the severity of heart conditions such as: heart attack — which can happen if a blood clot forms in one of the coronary arteries that supply blood to your heart; cardiomyopathy — a general term for a disease that weakens and enlarges your heart, including dilated, hypertrophic, and restrictive cardiomyopathy; and congestive heart failure — a condition that occurs when your heart can't pump blood effectively, caused by conditions including coronary artery disease, valvular heart disease, and cardiomyopathy.
You don't need to do anything special to prepare for a cardiac MRI. You can eat and drink normally and take your usual medications.
You'll need to let your doctor know if you have an artificial joint, such as a hip or knee joint. Metal objects can interfere with the magnetic field used in MRI, so you need to remove them before the scan.
You will wear a hospital gown during the procedure. You'll also need to remove any jewellery, glasses, or other metal objects you're wearing.
You'll lie on a table that slides into the MRI machine. A device called a coil will be placed around your heart to help focus the magnetic field and produce clearer images. You'll be asked to hold your breath for short periods while images are being taken, which helps to reduce blurring.
The MRI machine makes loud thumping and humming noises. You'll be given earplugs or headphones to help block out the noise. The procedure usually takes 30–60 minutes, but it may take longer if you have multiple scans or if your heart rate is very slow.
After the scan, you can go about your normal activities — there's no recovery time required. If you had contrast material injected into your vein, drink plenty of fluids for 24 hours to help flush it out of your system. You should call your doctor if you have any problems, such as shortness of breath, chest pain, or an irregular heartbeat. It may take a few days for the images to be analysed and interpreted by a radiologist, and your doctor will discuss the results with you at your follow-up appointment.
It doesn't use ionising radiation: Unlike other imaging tests such as CT scans, MRI doesn't use ionising radiation. This means that it's safe for pregnant women and children.
It produces clear images: MRI provides clear and detailed images of the heart and surrounding structures, allowing your doctor to make an accurate diagnosis.
It can be used to assess a variety of conditions: MRI can be used to assess a variety of heart conditions, including heart attacks, cardiomyopathy, and congestive heart failure.
It's non-invasive: MRI is a non-invasive procedure, meaning there's no need for surgery or recovery time.
There are no known risks associated with MRI scanning of the heart. However, if you have a pacemaker or other implanted device, you should not have an MRI scan, as the magnetic field used in MRI can interfere with these devices.
In very rare cases, people may have an allergic reaction to the contrast material used in MRI. This can cause symptoms such as hives and difficulty breathing. If you have a history of allergies, your doctor will likely give you medication to prevent a reaction.
The scan varies in length depending on the reason your doctor ordered it, but it typically takes an hour for a heart MRI. This includes the time it takes to position you on the table and perform the scan.
A Heart MRI can show your heart's size and shape and the location and extent of any damage to your heart. An MRI can also be used to assess the blood flow to your heart and look for blockages in your coronary arteries.
No, a heart MRI is not painful. You will be asked to lie still on a table while the scan is performed. MRI technicians will provide you with earplugs or headphones to help reduce the noise from the machine. Try to remain as still as possible during the scan.
Yes, you can drink water before a heart MRI. You can even eat, take medications, and wear regular clothes. There are no special preparations required for a heart MRI. But if you are claustrophobic, your doctor may give you a sedative to help you relax during the scan.
No, a doctor will not automatically recommend an MRI. An MRI is just one of many tests that can be used to diagnose heart conditions. Your doctor will consider your symptoms and medical history and determine whether an MRI is the best test for you. An MRI may not be necessary if your doctor can make a diagnosis based on your symptoms and a physical exam.
A cardiac MRI is a safe and non-invasive procedure. There are no known risks associated with the procedure. But if you were given a sedative to help you relax during the scan, there is a small risk of side effects such as drowsiness and dizziness. There is also a small risk of an allergic reaction to the contrast dye used in the procedure, but these risks are rare and will go away quickly.
