Biopsy

A biopsy is a small sample of tissue taken from the body so it can be examined under a microscope and tested chemically in the laboratories. Any area of the body can be biopsied.

Angiography and angioplasty

Angiography is a procedure that allows doctors to look at blood vessels in great detail using X-rays. If the doctors identify a narrowed portion (stenosis) of a blood vessel during the angiography procedure, they may stretch or widen it straightaway using a procedure called an angioplasty.

MRI scans

An MRI (magnetic resonance imaging) scan uses a magnetic field rather than x-rays to take pictures of your child’s body. The MRI scanner is a hollow machine with a tube running horizontally through its middle.
