It is particularly useful for diagnosing KS in the lymph nodes. To increase the detail of the picture, a dye containing iodine may be injected into a vein in your arm. This may make you feel hot all over for a few minutes. Once you are in a comfortable position the scan can be taken. The scan itself is painless but it will mean lying still for about 30-40 minutes.
Most people are able to go home as soon as their scan is over.
An endoscope is a telescope-like instrument which is passed down your throat. It allows the doctor to examine the inside of your body. A mild sedative helps you to relax during the test and a local anaesthetic will be sprayed onto your throat to prevent any discomfort as the tube is passed. This test is called a colonoscopy. The bowel must be empty for this test so a careful diet must be followed beforehand.
