CT of the neck is the preferred exam when evaluating the soft tissue structures of the neck. The scan includes the orbits through the top of the lungs and is used extensively to evaluate the glands and lymph nodes of the neck. IV iodinated contrast media is often indicated for an accurate evaluation of the vasculature and/or disease. The need for IV contrast is determined by the reason for the scan.
Eat lightly the day of the exam. Do not eat within one hour of your procedure.
