19 NCCN Guidelines for Patients ® : Follicular Lymphoma, Grade 1–2, 2017 2 Treatment planning Blood tests Imaging tests Imaging tests make pictures (images) of the insides of your body. They can show which sites have cancer. This information helps your doctors stage the cancer. More information on cancer staging is in Part 4. Your treatment team will tell you how to prepare for the test. You may need to stop taking some medicines and stop eating and drinking for a few hours before the scan. Tell your doctors if you get nervous when in small spaces. You may be given a sedative to help you relax. Imaging machines are large. You will likely be lying down during testing. At least part of your body will be in the machine. Figure 5 shows a CT machine, which is described next. After the test, you will likely be able to resume your activities right away. If you took a sedative, you will have a waiting period. You may not learn of the results for a few days since a radiologist needs to see the pictures. A radiologist is a doctor who’s an expert in reading the images. Diagnostic CT A CT ( c omputed t omography) of your chest, belly area, and between your hip bones is needed. A CT of your neck is sometimes useful to learn if cancer is present. CT takes many pictures of a body part from different angles using x-rays. A computer combines the x-rays to make detailed pictures. The picture is saved for later viewing by the radiologist. A contrast dye is used for diagnostic CT. It makes the pictures clearer. The dye will be injected into a vein in your hand or arm. You will also be given a liquid contrast to drink. The contrast may cause you to feel flushed or get hives. Rarely, serious allergic reactions occur. Tell your doctor and the technicians if you have had problems with contrast in the past. Whole-body PET/CT Sometimes CT is combined with PET ( p ositron e mission t omography). When used together, they are called a PET/CT scan. PET/CT may be done Figure 5 CT machine Pictures of the insides of your body can be made with an imaging test. During the scan, you will lie on a table that will move into the tunnel of the imaging machine. The pictures will be viewed by a doctor who will look for signs of cancer.
