Coronary CT Angiography in Istanbul is available at 5 hospitals in the Voumed network.

Coronary CT angiography, sometimes called virtual angiography, is a computed tomography method that produces detailed images of the heart and its coronary arteries without the need for a catheter. Traditional angiography involves threading a thin tube into the arteries, but this scan does the same job from the outside, using a fast CT scanner and a contrast agent given through a vein. It clearly shows the build-up of calcium and plaque in the artery walls and any narrowing they cause. It uses X-rays, as all CT does, with techniques designed to keep the radiation dose low.
