Diagnosis of Coronary Artery Disease (CAD) and Angina
- Magnetic resonance angiography (MRA) —The MRA test uses MRI technology to identify coronary artery blockages. This technique has its limitations and is not commonly used.
- Electron beam CT scan (EBCT) —This is a “heart scan” that uses some radiation to detect tiny calcium deposits in the lining of the coronary arteries. This technique is appealing because it is not invasive, physically exerting, or risky. However, results can often be incorrect or misleading, so research is still being done on EBCT.
- Computed tomography angiography (CTA) —CTA uses 64 slice CT imaging—along with an IV contrast injected in the hand or arm—to image the coronary arteries and look for blockages. This test is similar to coronary angiography, but poses less risk because there is no need for an invasive catheter placement.
