As a medical professional with expertise in diagnostic imaging, I can explain the process of a cardiac MRI.

A cardiac MRI, or magnetic resonance imaging of the heart, is a non-invasive diagnostic test that uses a powerful magnetic field, radio waves, and a computer to create detailed images of the heart's structure and function. Here's what typically happens during a cardiac MRI:


1. Preparation: The patient is asked to remove any metal objects that could interfere with the MRI machine. This includes jewelry, watches, and sometimes even metal implants, depending on their compatibility with the MRI.


2. Positioning: The patient lies down on a flat table that slides into the tunnel-shaped MRI machine. Cushions and straps may be used to help the patient stay in position and to reduce movement during the scan.


3. Contrast Agent: In some cases, a contrast agent may be used to enhance the images. This is typically injected into a vein in the arm before the MRI.


4. Scanning: The MRI machine uses a series of radio waves and magnetic field adjustments to collect data from different parts of the heart. The patient will hear knocking sounds during the scan, but it is painless.


5. Breathing and Heart Rate Monitoring: The patient is asked to hold their breath at certain times to ensure clear images. Heart rate and breathing are monitored throughout the procedure.


6. Image Acquisition: The MRI machine processes the data collected to create images of the heart. These images can show the size and shape of the heart, how well the heart is pumping, and the function of the heart valves.

7.
Completion: Once the scan is complete, the patient can leave the MRI machine and return to their normal activities.

8.
Interpretation: A radiologist will review the images and report the findings to the referring physician, who will discuss the results with the patient.
