If your doctor has scheduled you to have an X-ray exam, it is important that you understand why you have been asked to undergo this test and what steps are needed for a proper preparation.
A chest X-ray are often taken to check your general health and see if there has been any spread of the cancer to other parts of the body.
Ultrasound (US) imaging, also called ultrasound scanning or sonography, is a method of obtaining images of internal organs by sending high-frequency sound waves into the body. The reflected soundwaves’ echoes are recorded and displayed as a real-time, visual image. No ionizing radiation (X-ray) is involved in ultrasound imaging.
CT SCAN is an X-ray tube that rotates in a circle around the patient and takes a series of pictures as it rotates. The multiple X-ray pictures are reconstructed by a computer in axial slice images at different levels. Each level can be examined separately.
The scan takes from 10-30 minutes. You may be given a drink or injection of a dye, which allows particular areas to be seen more clearly. For a few minutes, this may make you feel hot all over. If you are allergic to iodine or have asthma you could have a more serious reaction to the injection, it is important to let your doctor know beforehand.
You will probably be able to go home as soon as the scan is over.
Magnetic Resonance Imaging (MRI) is a noninvasive imaging technique. This test is similar to a CT scan but uses magnetism instead of X-rays to build up cross-sectional pictures of your body. It is used to view organs, soft-tissue, bone, and other internal body structures.
An individual is not exposed to harmful radiation during this test.
