Exam 2 Flashcards
gastric folds
Rugae – folds of tissue in the mucosal and submucosal layers of the stomach. Provide elasticity allowing the stomach to expand. Provide increased surface area to absorb nutrients
Why would the technologist perform a PA abdomen instead of an AP?
reduce pt dose and puts the stomach/intestines closer to IR
What attaches to the stomach?
small intestine (duodenum)
Projections of stomach for hypersthenic vs sthenic patients.
stomach is more superior in hypersthenic patients so center higher
stomach is more inferior in sthenic patients to center lower
use PA axial view for hypersthenic patients to open up and show the greater and lesser curvatures
Narrowing of a vessel or lumen =?
stenosis
Inflammation of the stomach.
gastritis
Where does the stomach lay for oblique projections? (L1, L2, L3, etc.)
level of L1-L2
How long should the patient be NPO before an upper GI study?
8 hours
When are compression projections useful?
to permit adequate contrast filling and maximal distention
Evaluation of Hiatal hernias.
AP projection, tilt table to a trendenlenburg position
Why use double-contrast as opposed to single contrast?
in double-contrast studies small lesions are less easily obscured and the mucosal lining of the stomach can be more clearly visualized
Lesser curvature vs greater curvature
greater = lateral side
lesser = medial side
Hand-held compression of _____ for upper GI.
What stomach position for the barium to move to the pylorus? Fundus/cardia?
AP OBL LPO
Why “roll” the patient after drinking of contrast?
to coat the whole stomach
