(c) Double-unit setup. Two x-ray units (radiographic-fluoroscopic),
located in adjacent rooms, are used. The personnel consist of the radiologist and one,
or preferably two, x-ray specialists. Upon completion of fluoroscopy (including spot-film
radiography, if indicated), the x-ray unit is changed over and radiography is done. While
radiography is being performed on one patient, the examiner may step into the adjacent
room and start the fluoroscopic examination of another patient. This process continues,
back and forth, until the last examination is completed. The use of the double-unit setup
saves excess handling of litter patients, is time saving, and simplifies working
(2) Contrast medium should be prepared in accordance with the established
routine as prescribed by the radiologist. Eight to 16 ounces total volume per patient is
usually required during fluoroscopic filling. If perforation is suspected, barium is
inappropriate and an iodine medium should be substituted.
(3) Protective aprons and gloves should be laid out for the radiologist and
other interested medical personnel.
(4) The radiographic request form containing pertinent information regarding
the patient's case should be available to the radiologist at all times.
c. Fluoroscopic Examination.
Upon reporting, the patient is dressed in a suitable gown.
(2) The examination procedure should be explained to the patient so that
(3) The patient is directed, or assisted, to take a position between the table
and the fluoroscopic apparatus.
(4) A preliminary screening of the area under consideration is usually made
by the radiologist. The radiologist may request a scout film if the patient's history
indicates prior surgery or recent examinations.
(5) At a given signal from the radiologist, the specialist hands the patient a
cup of the contrast medium. Just before doing this, he should again stir the mixture.
(6) The examination proceeds as the patient ingests the contrast medium
and controls his respiration as directed by the radiologist.
The radiologist records the fluoroscopic images as necessary.
