21 NCCN Guidelines for Patients ® : Multiple Myeloma, 2019 Imaging tests Imaging tests take pictures (images) of the inside of your body. These tests are often easy to undergo. Before the test, you may be asked to stop eating or drinking for several hours. You should also remove any metal objects that are on your body. Imaging machines are large and may be very noisy. You will likely be lying down during testing. At least part of your body will be in the machine. Figure 7 on page 22 shows one type of imaging machine. Some imaging tests may use a contrast dye to make the pictures clearer. This contrast dye can cause damage to frail kidneys. Thus, it should be used with great care in patients with multiple myeloma. The types of imaging tests used for multiple myeloma are described below. Bone survey A bone survey—also called a skeletal survey—is a test that uses a set of x-rays to take pictures of your entire skeleton. A bone survey is done to check for broken or damaged bones caused by myeloma. MRI scan MRI uses radio waves and powerful magnets to take pictures of the inside of the body. It makes pictures of bone and bone marrow. This type of scan may show abnormal areas where myeloma cells have replaced bone marrow. An MRI scan of your whole body may be given when the bone survey doesn’t show any problems. These large machines are quite noisy, and you might want to bring ear protection from home. Only use plastic protectors and not any that contain metal. The loud, strange sounds in the machine are normal. When you are lying in the machine it might seem to be very close to your face. It works best to close your eyes and relax while the machine is working. Your doctor can prescribe a mild sedative to help you relax. You should let your health care provider know if you are claustrophobic or afraid of closed spaces. 2 Testing for myeloma Imaging tests Your medical records: ü Your doctors will order tests and schedule visits to talk about your care plan. ü It is helpful to keep track of your test results at all times.
