Other Imaging Tests
To learn more about the extent of disease and suggest a course of treatment, the doctor may order some of the following imaging tests:
Chest X-ray: A chest X-ray can show whether cancer has spread to the lungs.
Computerized tomography (CT) scan: This diagnostic test uses an X-ray machine and a computer to create detailed pictures of the body, including 3-D images. It provides detailed information about the size, shape, and position of a tumor. It may also provide information on enlarged lymph nodes that may contain cancer that has spread from the ovary.
As part of a CT scan, you may be asked to drink oral contrast or have an IV line (a tube that enters a vein in the body) for injection of a contrast dye. Contrast dye makes your organs more visible on the X-ray film.
Magnetic resonance imaging (MRI): This diagnostic test uses magnetic fields and radio (sound) waves to create computerized pictures of the pelvis and abdomen. The doctor views these pictures to see whether cancer has spread. You may be placed in a tube, which may feel confining to people who have a fear of enclosed spaces. A contrast dye might be used. The MRI is noisy while it is operating, so patients usually wear earplugs.
PET scan: This test detects the energy given off by a radioactive chemical in your bloodstream. First, you will have a very small dose of the chemical, called a radiotracer, injected into a vein in your arm. The tracer travels through the body and is absorbed by the organs and tissues being studied. Next, you will be asked to lie down on a flat examination table that is moved into the center of a PET scanner. This machine detects and records the energy given off by the tracer substance and, with the aid of a computer, this energy is converted into three-dimensional pictures. A physician can then look at cross-sectional images of the body organ from any angle in order to detect any functional problems.
