Cancer Imaging Tests

Imaging tests that help diagnose and track cancer include traditional x-rays and more advanced tests such as CAT scans, ultrasound and MRI. Radionuclide imaging tests such as PET scans use radioactive materials to detect areas of cancer spread.

X-ray Cancer

X-ray and Cancer

Reviewed By:Martin E. Liebling, M.D., FACP Summary An x-ray is a painless test in which an image of part of the body is created by using low doses of electromagnetic radiation and recorded on film or fluorescent screens. X-rays can be used to diagnose a wide range of conditions, from bronchitis to a broken arm. Depending upon …

Ultrasound and Cancer

Reviewed By:Mark Oren, M.D., FACP Summary An ultrasound test sends and receives high-frequency sound waves to create images of internal organs or tissues. Sound waves pass into the tissues of the area being examined. These sound waves are reflected (bounced back), recorded and displayed on a computer screen or television-type monitor. The technology used in ultrasound in …

Thermography

Thermography

Also called: Infrared Thermography Reviewed By:Mark Oren, M.D., FACP Summary Thermography is a test that measures the heat coming from the body. It has been approved by the U.S. Food and Drug Administration (FDA) to help detect breast cancer and other diseases, although its effectiveness has been the subject of debate. Thermography is typically performed in …

PET Scan

PET Scan

Also called: Positron Emission Tomography & Cancer Reviewed By:Mark Oren, M.D., FACP Summary Positron emission tomography is an imaging test used to diagnose and monitor cancer and other conditions. Commonly known as a PET scan, this test helps physicians to detect biochemical changes that may suggest the presence of cancer or other illnesses. The changes …

MRI

MRI

Reviewed By:Mark Oren, M.D., FACPMartin E. Liebling, M.D., FACP Summary Magnetic resonance imaging (MRI) is a safe and painless test that produces clear cross-sectional or three-dimensional images of the body’s tissues, even through bone and other obstructions. Unlike x-rays and computed axial tomography (CAT) tests, which use radiation, MRI relies on radiofrequency sound waves and …
