A cardiac MRI is a medical imaging technique. It uses powerful magnets and radio waves to create detailed images of the heart and surrounding blood vessels. It allows physicians to accurately diagnose various heart conditions. These include but are not limited to coronary artery disease, arrhythmia, and heart failure. It can also help evaluate the effectiveness of treatments for these conditions.
A cardiac MRI scan can assess the heart’s function in terms of its ability to pump blood. It is critical for individuals with heart conditions.
The procedure usually takes about 45 minutes. However, it is possible to perform it on an outpatient or inpatient basis in centers like Advanced Open MRI imaging and Elizebeth diagnostic imaging. Overall, the purpose of a cardiac MRI is to provide doctors with reliable insights about the heart and its function. It aids them in the diagnosis and treatment of various heart conditions.
What Is A Cardiac MRI?
In the medical field, the professional also calls a cardiac MRI a heart MRI procedure. This procedure uses powerful magnets and radio waves to create detailed images of the heart and surrounding blood vessels. It allows physicians to diagnose a wide array of heart conditions. Furthermore, it also facilitates the evaluation of the efficacy of treatments for these conditions.
Traditional x-ray affordable imaging uses ionizing radiation to produce images of the body. However, a cardiac MRI is non-invasive and does not expose the body to radiation. Instead, the procedure uses strong magnetic fields to align the hydrogen atoms in the body and radio waves to knock them out of alignment.
As the hydrogen atoms return to their original position, they produce a faint signal picked up by the MRI machine and used to create detailed images of the body’s organs and tissues.
Equipment For A Cardiac MRI
The primary equipment for a cardiac MRI is the MRI machine, which consists of a large, cylinder-shaped magnet that generates the strong magnetic field needed for the procedure. Usually, the examiner asks the patient to lie down on the table. Moreover, the table is flexible to moving in and out of the magnet. Specialized coils surround the area being scanned. These coils help in amplifying the signal produced by the hydrogen atoms.
Several types of coils may be used during a cardiac MRI, including body coils, surface coils, and phased array coils. The exact type used will hinge on the area being imaged and the required level of detail.
In addition to the MRI machine and coils, a cardiac MRI may also involve a contrast agent, a dye injected into the patient’s bloodstream to help enhance the images produced by the MRI machine. The contrast agent may be administered intravenously or by injection into the patient’s arm or hand.
How To Perform a Cardiac MRI?
Cardiac MRI is a very simple yet important process in the medical field today. It helps cardiac professionals in estimating the health condition of a patient. The process of undergoing a cardiac MRI typically involves the following steps:
Preparation
Before the MRI, it is necessary for the patient to remove any metal objects, such as jewelry or eyeglasses, and to change into a hospital gown. The patient may also be asked to refrain from eating or drinking anything for a certain period of time before the procedure, as food and drink can interfere with the MRI process.
Explanation of the procedure
Before the MRI begins, the technologist will describe the procedure to the person undergoing the procedure and answer any queries they may have.
Insertion of an IV line
An intravenous (IV) line will be inserted into the patient’s arm or hand if the radiologist is ready to uses a contrast agent during the open MRI heart scan,
Scanning
The technologist will position the patient and the specialized coils around the imaged area. Later, the patient is relocated into the MRI machine for an MRI scan. The MRI machine produces loud noises during the scan. In some cases, the examiner or radiologist gives earplugs or headphones to wear. The scan typically takes 30-60 minutes.
Review of images
After the procedure, the radiologist will critically evaluate the images. Later, the technician evaluates the MRI results. It helps in providing detailed diagnostic analysis to the patient’s physician.
What Is The Role Of A Cardiac MRI?
Cardiac MRI plays a significant role in analyzing the overall cardiac condition of the patient. Also, professionals recommend a cardiac MRI scan for a variety of purposes, including:
Diagnosing heart conditions
A cardiac MRI can produce detailed images of the heart and surrounding blood vessels, allowing physicians to accurately diagnose coronary artery disease, heart failure, and arrhythmia.
Evaluating the effectiveness of treatments
In the medical field, evaluating whether the drugs and treatment are working on the patient can be challenging. It is where cardiac MRI can make a difference.
A cardiac MRI scan can assess the heart’s function in terms of its ability to pump blood, which can help physicians determine if a particular treatment is effective.
Monitoring heart conditions
A cardiac MRI can monitor a heart condition’s progression over time, allowing physicians to track changes and adjust treatment as needed.
Overall, the purpose of a cardiac MRI is to provide doctors with valuable information about the heart and its function, aiding in the diagnosis and treatment of various heart conditions.

Cardiac MRI – Risks & Considerations
Undergoing a heart MRI scan comes with several probable issues and conditions. Have a look at some of these:
Allergic Reaction
One potential risk of an open MRI heart scan is an allergic reaction to the contrast dye used in cardiac MRI exams. This dye, injected into a vein, helps improve the visibility of certain structures in the heart and blood vessels.
Although rare, some people may experience serious allergic reactions to the dye, ranging from mild to severe. The top indicators that there is a negative reaction can be apparent due to the appearance of a rash, hives, difficulty in breathing, and low blood pressure.
Exposure To X-Rays
Another potential risk of a cardiac MRI is using the magnetic field and radio waves. These may interfere with certain devices that rely on similar technologies. Also, it is imperative to inform the healthcare provider if you have any medical device implanted in your body before the heart MRI procedure.
In addition to the above risks, several considerations may affect a person’s suitability for a cardiac MRI. For example, people with severe claustrophobia (fear of confined spaces) may find it difficult to undergo the exam, as it requires lying still in a narrow tube for an extended period of time.
Some people may also be unable to undergo a cardiac MRI if they are pregnant or have certain types of metal in their body, such as a metal joint replacement or certain types of tattoos.
In conclusion, cardiac MRIs are an important diagnostic tool for evaluating the heart and its blood vessels. While there are potential risks and considerations to be aware of, they are generally considered safe and effective. It is important to discuss any concerns or questions you may have with your healthcare provider before the exam to ensure that it is the right choice for you.
Conclusion
The images generated by the procedure can help healthcare providers identify and diagnose a wide range of heart conditions, including blockages in the coronary arteries, heart structure abnormalities, and heart muscle damage after a heart attack.
One of the main advantages of cardiac MRIs is their ability to provide detailed, high-quality images of the heart without ionizing radiation, which can be harmful to the body. In addition, cardiac MRIs have a lower chance of resulting in post-procedure difficulties.
Overall, cardiac MRIs are a valuable diagnostic tool for evaluating the heart and its blood vessels. However, they can help healthcare providers accurately diagnose and treat a range of heart conditions, leading to improved patient outcomes. If you are experiencing symptoms of a heart condition, it is important to discuss the potential benefits and risks of a cardiac MRI with your professional doctor.
