This is a technique using a contrast medium to outline blood vessels. The procedure may be done in a variety of ways, depending on the indications. Examples include coronary angiography, performed in the cardiac catheterisation laboratory, by an interventional cardiologist to examine the heart for blockages; peripheral angiography, done by a vascular surgeon also performed in a cardiac catheterisation laboratory, to look for blockages in the arteries to the lower limbs and CT angiography, performed by a radiologist in the X-ray department to look at a number of different organ systems.

Stenting involves stretching a narrowed area of the artery with a small cylindrical balloon. Once the narrowing has been stretched a stent is inserted (a fine mesh cylinder usually of stainless steel) that supports that part of the artery.
