CT Scan today

Today I will have my CT scan.  It is a relatively simple proceeder. Or so I am told. Ive never had one.I will fast for 2 hours. I go in to Scripps clinic at 12:30 and have blood drawn. They want to be sure my kidneys are working well before they give me the contrast dye. Then I go down to radiology where they give me the contrast dye to drink. I wait an hour. Then they do the CT scan. Im glad I am having this procedure. Something isn't right in my tummy. There is a fullness there. A discomfort.  I don't really want to each much. I am eating very low fat as per doctors orders.  I don't want to eat much at any one time. Im sticking to simple things, such as non fat yogurt, oatmeal, toast, graham crackers, fresh fruit. I absolutely don't want any meat of any kind . Even vegetables are unappealing. I may make some soup today. 
What is a CAT or CT scan? Funny you should ask. 

What is CT Scanning of the Body?

CT scanning—sometimes called CAT scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor, printed or transferred to a CD.

CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams.

Using specialized equipment and expertise to create and interpret CT scans of the body, radiologistscan more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and musculoskeletal disorders.
