Computed Tomography (CT)
Using a series of two-dimensional X-ray images, Computed Tomography, also know as CT or CAT scan offers a three-dimensional image of internal organs. Physicians often request a CT scan to diagnose cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders. Creating cross sections-sections of images of bones, blood vessels and soft tissue, a CT scan is the best choice especially because the amount limited risk as compared to the great detail the test provides.
As with most diagnostic tests, notify your physician if you are pregnant or think you could be pregnant before the scheduling your CT scan.
Some tests require a contrast material administered through a vein in your arm. Occasionally, people have mild reactions like a rash. If you have ever had a reaction to contrast material, let your doctor know.
Before the test, you want to avoid eating or drinking for about 2 hours before your CT scan. Leave all valuables at home, including jewelry, and any metal or electronic devices.
Depending on the areas your doctor is imaging, the average CT scan is less than 15 minutes. The scanning is painless, and for most people the buzzing and clicking of the machine as it takes your images is what most people comment on and remember.
