Cardiac CT

A Cardiac Computed Tomography (CT) Scan is an imaging test that creates 3D and cross sectional images of the heart using

x-rays

from multiple angles. An electron beam CT (

EBCT

) is used to detect

calcium deposits

(blockages) in the coronary arteries that supply blood to the heart. A multidetector CT (

MDCT

) takes multiple rapid scans that can show issues in the heart’s structure and pumping function.

Contrast dye

is injected into a vein prior to the test to help highlight the

blood vessels

to create a clearer picture. The contrast dye may affect patients with pre existing

kidney conditions

; a

cardiac MRI

may be performed instead. A

radiologist

conducts CT scans with findings sent to the patient’s

cardiologist

. The images of the heart are used to diagnose heart disease, defects or injuries to the heart valves,

blood clots

,

tumours

and

pericarditis

.
