Cardiac CT imaging, also known as cardiac computed tomography or coronary CT angiography, is a non-invasive medical imaging test that provides detailed images of the heart and its blood vessels. The test uses X-rays and advanced computer technology to create cross-sectional images of the heart, which can reveal the presence of calcium deposits, plaque buildup, or blockages in the coronary arteries. Cardiac CT imaging can also assess heart function and structural abnormalities. Patients may receive a contrast dye injection to enhance the images. The procedure is quick, typically taking about 10 to 15 minutes, and is considered safe. Results from cardiac CT imaging can help guide treatment decisions and risk assessments for heart disease.
