Side effect of cervical ct scan?
The red dye that is used in a CT scan is a contrast dye. The objective of the dye is so that certain parts of the body will show up clearer in an x-ray. Contrast dye is generally given by IV into the hand or arm.
A tri-phasic CT scan is a scan which will show three different stages of dye uptake in the body. The first phase will be before the injection of the dye, the second stage will be for when the dye is in the arteries (roughly 20 seconds after injection) and the third phase will be when the dye has reached the veins (a few minutes later). Sometimes a fourth scan is also done to show the dye uptake in the kidneys and bladder. A tri-phasic scan clearly delineates lesions in the liver and will show problems and irregularities in the arterial and lymphatic system.
The metal that is used as a dye in CT scans is water soluble iodine or barium. These are sometimes avoided by patients because of allergies to the metals.
Theres no problem about eating before neck ct scan,if your concern is if the food you intake might affect the out come,but doctors might advice you not to take any food if you will be given dye,cause some patient tends to vomit when given dye.....

CT myelography (a test in which dye is injected into the spine) may demonstrate the cerebrospinal fluid flow between the spinal subarachnoid area and the cyst.
The nursing responsibilities during a CT scan may vary from place to place. The nurses often insert an IV for contrast dye and ensure the patient is comfortable.
Yes, brain tumours can show up very clearly on CT scans especially if the patient is injected with an X-ray dye.
Many CT scans of the abdomen involve injecting a dye into the vein. This dye "lights up" blood vessels and may make it easier to diagnose certain conditions. the dye can also be toxic to the kidneys. The blood test is a test of kidney function. If abnormal, the radiologist may either not use dye or use a smaller amount so as not to injure the kidney even more. CT scans without dye do not require baseline blood tests beforehand.
