Why is an ultrafast computed tomography (CT) scan performed?

An ultrafast computed tomography (CT) scan is a procedure used to diagnose heart disease. Some reasons for which an ultrafast CT may be performed include, but are not limited to, the following:

  • to assess the condition of the coronary arteries
  • to assess heart tissue damage after a heart attack (also called myocardial infarction, or MI)
  • to assess the patency (openness) of coronary artery bypass grafts

Ultrafast CT is used primarily for the diagnosis of coronary artery disease, particularly in persons who have no symptoms of the disease but who have significant risk factors for the disease. Ultrafast CT should not be considered a substitute for cardiac catheterization. Computed tomography measurement of coronary calcium is not considered relevant in patients who have already had a heart attack or undergone coronary bypass surgery or coronary angioplasty.

There may be other reasons for your physician to recommend an ultrafast CT.
