Document Summary

Procedures and techniques of radiology and diagnostic imaging. Visual imaging of the distribution of ventilation or blood flow in the lungs by scanning the lungs after the patient has been injected with or has inhaled radioactive material. Noninvasive scanning technique that enables the visualization of the shape, size, and consistency of the spleen after the injection of radioactive red blood cells. Nuclear imaging procedure that shows how the blood flows to the tissues and organs. Tracking of radioactive material allows the physician to see the perfusion of blood to the tissues and organs. Oral administration of a radiopaque contrast medium, barium sulfate, which flows through the gi system. X-ray films are obtained at timed intervals to observe the progression of barium through the small intestine. X-ray technique used to construct a detailed cross-section, at a predetermined depth, of a tissue structure. Useful in identifying the space-occupying lesions in the liver, brain, pancreas, and gallbladder.
