procedure that examines the size and filling of the pancreatic and biliary ducts through direct radiographic visualization with a fiberoptic endoscope

visualization of the gallbaldder through X-ray following the oral ingestion of pills ocntaining a radiopaque iodinated dye

combining the techniques of fluoroscopy, radiography, and cinematography of by filming the images that develop of a fluorescent screen with a movie camera

painless noninvasive diagnostic X-ray procedure using ionizing radiation that produces a cross-sectional image of the body

x-ray visualization of the bladder and urethra during the voiding process, after the bladder ahs been filled with contrast material

X-ray images of blood vessels only, appearing without any background due to the use of a computerized digital video subtraction process

studying the structure and motion of the heart

examine the function of an organ or a body part by using a fluoroscope

noninvasive scanning procedure that provides visualization of fluid, soft tissue, and bony structures by using electromagnetic energy

introdcution of contrast medium into the lumbar subarachnoid space through a lumbar puncture to visualize the spinal cord and vertebral canal through X-ray examination

noninvasive demonstrates the biological function of the body before anatomical changes take place

visualiztion of the entire urinary tract

examination that determines the position, size, shape, and physiologiacl function of the thyroid gland through the use of radionuclear scanning

recording the emission of radioactive waves using a gamma camera after an intravenous injection of a radionuclide material into the particualr part of the body being studied

placement of radioactive sources in contact with or implanted into the tissues to be treated

apparent changes in frequency of sound or light waves emitted by a source as it moves away from or toward an observer

emission of light of any wavelength (usually ultraviolet) when exposed to light of a different (usually shorter) wavelength

radiotherapy in which needles or wires that contain radioactive material are implanted directly into tumor areas

process in which a neutral atom or molecule gains or loses electrons and thus acquires a negative or positive electric charge

exposure to any form of radiant energy
