MRI and MRA of the Heart (Fall 1995)
Fall 1995 pages 1-2 MRI and MRA of the Heart Magnetic Resonance Imaging (MRI) technology is based on the principle that protons within body tissues and fluids, when placed in a magnetic field, can absorb and subsequently emit radio frequency signals. Differences in signal strength are then used to generate images. Magnetic Resonance Angiography (MRA) evolved as a modification of MRI technology. In an MRA, the body is placed in a homogeneous magnetic field. A selected volume of flowing blood is magnetically depolarized with a radio frequency pulse and acts as an internal contrast agent to static tissue. It...

Article Overview
This premium article covers cardiac magnetic resonance imaging and magnetic resonance angiography guidance from CPT in the fall 1995 issue of CPT Assistant. It is aimed at coders, billing staff, and clinical documentation teams who need to understand the general categories of cardiac MRI/MRA services discussed, including morphology, function, velocity flow mapping, and chest angiography, along with the article’s discussion of how these topics fit into CPT reporting.
Why This Topic Matters
Cardiac MRI and MRA services can overlap across imaging purposes and body regions, so this article helps readers orient themselves to the CPT framework in effect at the time. It is useful for identifying which broad service categories are addressed and for locating the codes and related guidance discussed in the full article.
