It can show which body parts have cancer. A radiologist is a doctor who is an expert in reading images. He or she will convey the test results to your doctor. Diagnostic CT scan CT takes many pictures of a body part from different angles using x-rays. See Figure 5 . A computer combines the x-rays to make detailed pictures. A contrast dye should be used. It makes the pictures clearer. CT is needed if your organs are enlarged. Leukemia cells can build up in lymph nodes, the spleen, and the liver. If needed, a CT of your chest, belly area, and between your hip bones is advised. PET/CT scan Sometimes CT is combined with PET ( p ositron e mission t omography). PET shows how your cells are using a simple form of sugar (glucose). PET/CT is often not useful for CLL. If given, it is used to direct a needle into a lymph node for a biopsy. Your lymph nodes may be tested if your doctor thinks that CLL is turning into a fast-growing cancer. Heart tests Some cancer treatments can damage your heart. To plan treatment, your doctor may test how well your heart pumps blood. You may get an echocardiogram or MUGA ( m ulti g ated a cquisition) scan. An echocardiogram uses sound waves to make pictures of your heart. A MUGA scan makes pictures using a radiotracer and special camera.

The pictures will be viewed by a doctor who will look for signs of cancer. Copyright © 2019 National Comprehensive Cancer Network ® (NCCN ® ). www.nccn.org
