Iodinated contrast is a form of intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiographic procedures. Some pathologies, such as cancer, have particularly improved visibility with iodinated contrast. The radiodensity of iodinated contrast is 25–30 Hounsfield units (HU) per milligram of iodine per milliliter at a tube voltage of 100–120 kVp. WebThe term “ computed tomography ,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the …

WebOften the PET/CT is repeated to monitor the effect of treatment of a particular disease. Most commonly PET utilizes 18 F-FDG as a radiotracer, the short half-life of which (110 min) reduces radiation exposure compared with other commonly used radionuclides such as 99mTechnetium (6 hours) and 201Thallium (72 hours).
