Magnetic Resonance Imaging

Cardiac magnetic resonance imaging MRI is used as both a functional and anatomical cardiac imaging test. It offers excellent soft tissue detail and the ability to quantify cardiac function. MRI scans can be performed with or without gadolinium contrast depending on what information is needed. Unlike computed tomography (CT), MRI does not use X-ray radiation, but patients with metal implants may have contraindications for MRI use because MR will heat up most metal objects. MRI exams usually take much longer than CT scans. How does MRI work? MR creates images by using powerful magnets to polarize hydrogen atoms in water (the body is made of of more than 80% water) so they face in one direction. A radiofrequency pulse is then used to ping these atoms, causing them to wobble, or resonate. The MRI coils detect this and computers can assemble images from the signals. Basic MRI scans will focus on the resonance of fat and water in two different sequences, which highlight and contrast different features in the anatomy.

Cardiac MRI findings can predict incident CVD years before onset

Prior imaging of the descending thoracic and abdominal aorta in study participants revealed thoracic aortic wall area (AWA), plaque prevalence and plaque volumes to be independently associated with incident CVD.

A key update: 1 year later, no signs of long-term heart damage among college athletes who had COVID-19

More than 3,500 college athletes with a confirmed COVID-19 diagnosis were included in the new study. The median follow-up period was more than one full year. 

A dedicated Cardiac MRI scanner. The presence of myocardial fibrosis on cardiac MRI can help anticipate adverse arrhythmic events and  may offer a way to improve patient selection for cardiac implantable electronic devices (CIEDs). This is a dedicated cardiac MRI system at Baylor Scott White.

Could cardiac MRI become the reference standard for diagnosing heart failure?

Cardiac MRI may offer a more accurate and less invasive method for diagnosing heart failure, a new study published in the European Heart Journal shows.
