Basics of Computer Tomography
Computerized Tomography scan in medical terms, uses computers and x-rays to view your body parts in cross-sections. It is a giant hollow cylindrical machine with a doughnut-shaped cavity in which your body goes, around which the x-ray head rotates. It signals the computer to produce various thin slices of images of your body parts on the computer. Thus, creating clear and detailed pictures of your affected body part for a definite diagnosis by the doctor.
CT Scan with Contrast
It is also a type of CT Scan in which a contrast material or dye is used to highlight a clearer image of specific tissues. The medical practitioner either asks you to drink the contrast material or injects that into your body.NO; it is not harmful to your body, and most of the time, it is passed in urine in 24 hours.
Preparations for a CT Scan
There’s nothing much you have to do.
