What is Contrast Media? - correct answer ✔✔Solutions or gases introduced into the body to
provide contrast on a radiograph between adjacent tissues. (Page 91)
What are the 3 general types of contrast media? - correct answer ✔✔1. Barium-based media
2. Iodine-based media
3. Air (Page 91)
What makes Barium-based media special for contrast media? - correct answer ✔✔It is inert and
cannot be absorbed by the body. (Page 92)
What examination is Barium-based media best for? - correct answer ✔✔Since the body cannot
absorb is, this makes it the best medium of choice for gastrointestinal (GI) studies. (Page 92)
What makes Iodine-based media special for contrast media? - correct answer ✔✔X-rays do not
readily pass through _____________, solutions that contain this element are placed in organs
and blood vessels to provide contrast between these two structures and their surrounding
tissues. (Page 92)
, What makes Air special for contrast media? - correct answer ✔✔It is easily penetrated by x-rays,
thus providing contrast between lung tissue, vessel markings, and air sacs. (Page 92)
What examination is Air best for? - correct answer ✔✔It is primarily used in chest x-ray. (Page
92)
What does CT and panoramic tomography primarily image? - correct answer ✔✔Skull, Facial
bones, Nasal bones, Mandible, Temporomandibular joints (TMJ's), and Sinuses. (Page 92)
What does the Thoracic Cavity include? - correct answer ✔✔Bones and tissues of the chest
region. (Page 92)
What is the most common place radiographed region of the body? - correct answer ✔✔The
Thoracic Cavity. (Page 92)
What can be evaluated in a thoracic study? - correct answer ✔✔Evaluate fluid in the lungs,
overexpansion, collapsed lungs, tumors, heart enlargement and other heart and lung
abnormalities, as well as fractures of the ribs, sternoclavicular joints, and sternum. (Page 92)
What are your upper extremities? - correct answer ✔✔Fingers, hands, wrists, forearms, elbows,
humeri, shoulders, clavicles, acromioclavicular joints, and scapulas. (Page 92)
What are your lower extremities? - correct answer ✔✔Toes, feet, heels, ankles, lower legs,
knees, patellae, femurs, hips, and pelvis. (Page 92)
Why do we radiograph the extremities? - correct answer ✔✔Evaluate bone fractures,
dilocations, arthritis, osteoporosis, and tumors. (Page 92)
What does the Spine include? - correct answer ✔✔Cervical, Thoracic, Lumbar, Sacroilliac joints,
Sacrum, and Coccyx portions. (Page 92)
