• Structural heart diseases, including cardiomyopathies

It gives doctors detailed images of the heart. This helps them make accurate diagnoses and plan effective treatments. Radio Frequency in Cardiac MRI is a big step forward in heart care.

The MRI Procedure: What to Expect

Getting an MRI can seem scary, but knowing what to expect helps a lot. Medical experts guide patients through each step to make them feel safe and comfortable.

Preparation for an MRI Scan

Getting ready for an MRI is important. Patients should remove metal items like jewelry and glasses before the scan. They should also skip heavy meals and caffeine a few hours beforehand.

People with metal implants or claustrophobia should tell their doctor. These things might change how the MRI is done.

During the Procedure: Inside the MRI Machine

During the scan, patients lie on a table that moves into the MRI. The machine uses a strong magnetic field and radio waves to create detailed images. They need to stay very quiet and not move for 15 to 90 minutes.

Inside, patients might hear loud sounds. Earplugs or headphones help block out the noise. Some places even offer video goggles to help relax.

Post-MRI Care and Considerations

After the MRI, patients can usually go back to their normal day unless told not to. It’s important to follow any instructions given, like if contrast material was used.

Some might feel sick or itchy from the contrast. These feelings usually go away, but tell a doctor if they last.

Knowing what to expect from an MRI makes the experience easier. It helps patients feel more prepared and less stressed.

MRI With and Without Contrast: Understanding the Difference

MRI technology lets us see detailed images with or without contrast agents. These agents help highlight specific areas of the body. Cardiac MRI is key for diagnosing and monitoring heart conditions.
