RAD 112 EXAM WITH COMPLETE
SOLUTIONS GRADED A+
6 main digestive system organs - Answer-Oral cavity, pharynx, esophagus, stomach,
small intestine, and large intestine
3 parts of the small intestine - Answer-duodenum, jejunum, ileum
Portions of the large intestine - Answer-Cecum, Ascending colon, transverse colon,
descending colon, sigmoid colon, rectum, and anus
Dual function of the pancreas - Answer-Endocrine (release hormones like insulin)•
Exocrine (produce digestive juices)
Main function of the liver - Answer-produce bile to aid in the breakdown of fats
Gallbladder function - Answer-Stores and concentrated bile for future use, releases bile
when stimulated
Thoracic organs within mediastinum - Answer-Thymus, heart and great vessels,
trachea, esophagus
What makes up the bony thorax? - Answer-Sternum, 2 clavicles, 2 scapulae, 12 pairs of
ribs, 12 thoracic vertebrae
PA chest exposure evaluation - Answer-No motion= sharp outlines of ribs, diaphragm,
and heart borders, and sharp lung markings demonstrated
Faint outlines of at least mid thoracic and upper thoracic vertebrae and posterior ribs
visible through heart and mediastinal structures
PA Chest position evaluation: Chin elevated= - Answer-No superimposition over lung
apices
PA Chest position evaluation
Forward shoulder rotation= - Answer-No superimposition of scapulae over lung field
PA chest position evaluation
No rotation= - Answer-SC joints equidistant from center spine and lateral costal margins
to vertebral column equidistant
, PA Chest position evaluation
Respiration= - Answer-visualize a minimum of 10 posterior ribs above diaphragm
Left Lateral Chest CR - Answer-T7, mid-thorax, horizontal beam
Left Lateral Chest Collimation - Answer-On 4 sides to area of lung fields
Left Lateral Chest anatomy demonstrated - Answer-Entire lungs demonstrated from
apices(top) to costophrenic angles (bottom) and from sternum (anteriorly) to posterior
ribs/thorax (posteriorly)
Left Lateral Chest exposure evaluation - Answer-Sharp outlines of diaphragm and lung
markings• Visualize lung markings through heart shadow and upper lung areas
Left Lateral Chest position evaluation - Answer-Chin and arms elevated= No excessive
soft tissue superimposing apices
No rotation= posterior ribs and costophrenic angles on side away from IR projected
slightly (1cm) posterior
Hilum region approximately centered to IR
Anterior Oblique Chest CR - Answer-T7, midway between MSP and lateral margin of
thorax, horizontal beam
Anterior Oblique Chest collimation - Answer-Collimate on 4 sides to area of lung fields
(top border of light field to level of vertebral prominens )
Anterior Oblique Chest Anatomy Demonstrated - Answer-Both lungs from apices (top)
to costophrenic angles (bottom)
Anterior Oblique Chest position evaluation - Answer-Distance from outer rib margins to
vertebral column on side furthest from IR should be approx. 2x distance of the side
closest to IR
Anterior Oblique Chest exposure evaluation - Answer-Outline of diaphragm and heart
appears sharp• Visualization of vascular markings throughout lungs and rib markings
(except through densest regions of heart)
Posterior oblique chest CR - Answer-T7, midway between MSP and lateral margin of
thorax, horizontal beam
Posterior Oblique Chest Collimation - Answer-14x17
Posterior Oblique Chest Anatomy demonstrated - Answer-Both lungs from apices (top)
to costophrenic angles (bottom)
