In honor of Stroke Awareness Month, Galichia Heart Hospital is offering Calcium Scoring for only $25 -- a savings of hundreds of dollars off traditional pricing -- now through May 31. Cardiac calcium scoring uses a special X-ray test called computed tomography (CT) to check for the buildup of calcium in plaque on the walls of the arteries of the heart (coronary arteries). This test is used to check for heart disease in an early stage and to determine how severe it is. Cardiac calcium scoring is also called coronary artery calcium scoring.
