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.

One-stop CT, MR imaging: Future in diabetic care?

Quantifying body fat and other clinical factors in obese patients with diabetes using CT or magnetic resonance (MR) may help physicians detect and manage comorbidities such as cardiovascular disease, according to a review published in the May issue of Diabetes Technology & Therapeutics. But is that enough to justify “one-stop shop” imaging?
