Magnetic resonance imaging uses a powerful magnetic field and radio wave pulses to create diagnostic medical images. Dr. Alberto Morales and the team at South Tampa Cardiology in Tampa, Florida, use cardiac MRIs to examine the heart, its health and function. For comprehensive assessment of your heart’s health, call South Tampa Cardiology for an appointment.
Though the equipment looks much like a CT scanner, MRI (magnetic resonance imaging) devices don’t use radiation in image formation, so these present a safer alternative for patients who must avoid additional radiation exposure, such as pregnant women or people undergoing radiation therapy.
A non-invasive procedure, cardiac MRIs give a picture of heart health, and it is commonly used to diagnose and assess such conditions as:
MRIs may be used in conjunction with other tests to confirm or expand on their findings.
Generally, MRIs are quite safe. However, patients with metal implants or pacemakers may not be candidates for MRI imaging. The strong magnetic fields used in MRI procedures may cause issues with things such as:
A particular dye, called gadolinium, may be injected intravenously. This is a different dye than used with CT scans. Allergic reactions to it are rare but possible.
As with a CT scan, you lie on a table that moves through a very large doughnut-shaped scanner. The MRI technician controls the movement of the table into the scanner.
As long as you have removed all metal, jewelry, body piercings, and watches, there’s little risk to you.
The machine makes a variety of noises as it functions, including whirring sounds and loud thumps. You may be offered earplugs or headphones.
You may be asked to hold your breath during parts of the exam to provide clearer images.
There’s no feeling or sensation.
Both the electromagnetic and radio waves pass harmlessly through the body.
The entire procedure may take up to 90 minutes, but there’s no effect on you, and you can drive safely home after the procedure.
