Medical Imaging
Your doctor may ask for tests to be done in the radiology department to see if any lymph nodes inside your body are swollen and if your liver or spleen are enlarged.4,8
Ultrasound
An ultrasound test is painless and gives a good view of the inside of your abdomen. You will be asked to lie on your back. Your abdomen will be exposed and some clear gel will be spread on it. The technician will then move a metal probe about the size of a large pen backward and forward across your skin. This transmits very high-frequency sound waves into your abdomen, which then bounce back and are picked up and used to form a picture of your internal organs.4
Computed Tomography (CT)
In a CT scan, x-rays are beamed from different angles all around you to build a 3-dimensional picture of the organs inside your body. The examination may include the injection of a contrast agent into your bloodstream to improve the visibility of some of your organs to x-rays. The CT scan is painless (except for the prick of the needle for the injection) and lasts about 15 minutes.4
You will lie on the examination table while the CT machinewhich is shaped like a large, upright doughnutmoves over you, making a whirring noise as it rotates to different positions to scan your body. You will have to lie still throughout the entire exam, which usually lasts about 15 minutes.4
If a contrast agent is used, the radiographer will place a needle into your vein and inject the agent into your bloodstream. The contrast agent often produces a warm feeling as it goes into your vein, but otherwise it should be painless.4
Magnetic Resonance Imaging (MRI)
An MRI scan can also take a 3-dimensional picture of your internal organs, but does so without x-rays. Instead, it uses a very strong magnet and high-frequency radio waves. The experience of an MRI scan for the patient is very similar to that of a CT scan, but is a lot noisier and lasts longerup to one hour. It makes loud thumping noises, but you may be given headphones or earplugs to block out the sound. A small minority of patients experience claustrophobia when they are in the "tube" of an MRI device, which may feel confining.4
All of these tests will help the doctor judge what treatment is needed, if any.
