Diagnostic scans

Your doctor may use a scan to better understand or diagnose sarcoma.

There are several kinds of scan used depending on the area your doctor is examining.

X-ray

Uses x-radiation to take images of dense tissues inside the body such as bones or tumours.

Ultrasound

A scan that uses sound waves to create images from within the body.

CT

The Computer Tomography (CT) scan takes a number of x-rays to make a 3D image of an affected area.

EUS

An Endoscopic Ultrasound (EUS) uses a tube-like instrument called an endoscope with an ultrasound scanner attached. This is put inside the body to look inside the gut to investigate GIST tumours.

PET

The Positron Emission Tomography (PET) scan shows up changes in tissues that use glucose as their main source of energy. It involves an injection of a very small amount of a radioactive drug into the body.

MRI

Magnetic Resonance Imaging (MRI) uses magnets to create an image of the tissues of the body.

Bone scan

Uses radioactive chemicals called radionuclides which are injected, swallowed or breathed into the body, to take images of bones.
