Chondrosarcoma Diagnosis

In addition to a complete medical history and physical examination, diagnostic procedures for chondrosarcoma include biopsies and several different types of imaging. You may undergo one or more of these procedures.

Biopsy

During this procedure, tissue samples are removed (with a needle or during surgery) from the body for examination under a microscope; this is done to determine if cancer or other abnormal cells are present.

X-ray

This is a diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.

Computed Tomography Scan (also called a CT or CAT scan)

This is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce both horizontal and vertical cross-sectional images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.

Magnetic Resonance Imaging (MRI)

This is a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.

PET/CT (Positron Emission Tomography/Computed Tomography) Scanning

PET/CT Scanning, one of the latest advances in tumor imaging, is used as a diagnostic tool at Stanford. It combines CT imaging with positron emission tomography (PET), which monitors the biochemical functioning of cells by detecting how they process certain compounds, such as glucose (sugar) Imaging the tumor is important to confirm the diagnosis and to determine the cancer stage and spread, which will guide treatment.
