CT Triphasic Abdomen is a safe and non-invasive test, but it does expose patients to a small amount of radiation. Patients should inform their doctor if they are pregnant or breastfeeding, as radiation can be harmful to developing fetuses and infants. Patients should also inform their doctor if they have any allergies or kidney problems, as the contrast agent can sometimes cause adverse reactions. For transplant patients, it is important to inform the medical team of any medications being taken, as they can affect the results of the test.
