Term
Patient should be NPO for at least __ prior to exam
Definition
8 hours
Term
goal of patient having an empty stomach prior to exam is:
Definition
Prevents excessive fluid from accumulating in the stomach and diluting the barium
Term
prior to exam, a preliminary radiograph or a scout film of the abdomen (KUB) is taken to delineate the:
Definition
liver, spleen, kidneys, psoas muscles, and bony structures and to detect any abdominal or pelvic calcifications or tumor masses
Term
Begin with patient in erect position
Barium 30%-50% weight/volume
Give barium to patient to hold in the left hand
Definition
Single contrast method
Term
stomach exams demonstrate:
Definition
stomach filling, size, shape, and emptying of the duodenal bulb
Term
Give patient a gas producing substance (EZ Gas®)
Instruct patient to refrain from belching until the examination is complete
Definition
instructions for double-contrast method
Term
having patient in recumbent position, and instruct patient to turn from side to side serves to:
Definition
coat the mucosal lining of the stomach
Term
prior to exam, patient may be given ___ to relax the gastrointestinal tract
Definition
glucagon or other anti-cholinergic medications
Term
advantage of double contrast study
Definition
small lesions are less obscured and the mucosal lining of the stomach can be more clearly visualized
Term
Recumbent
Adjust patient midline of the grid to sagittal plane passing halfway between the vertebral column and the left lateral border of the abdomen
Definition
positioning for PA stomach
Term
for PA stomach, center IR 1-2 inches above the lower rib margin at the level of L1-L2 when patient is ___
Definition
prone
Term
for PA stomach, center the IR 3-6 inches lower than L1-L2 when patient is ___
Definition
upright
Term
CR for PA stomach
Definition
Perpendicular to the midpoint of the IR
Term
patient instructions for PA stomach
Definition
Breathe in, Breath out, hold it
Don’t breathe, don’t move
Term
Prone
MSP centered to grid
Sthenic patient-center IR at the level of L2 (L2 is about 1-2 inches above the lower rib margin)
Hypersthenic patient, somewhat higher
Asthenic patient, somewhat lower
Definition
part position for PA Axial
Term
CR for PA axial
Definition
Directed to the midpoint of the IR at an angle of 35-45 degrees cephalad
Term
patient instructions for PA Axial stomach
Definition
Breathe in, Breath out, hold it
Don’t breathe, don’t move
Term
the ___ view gives the hypersthenic stomach much the same configuration as the average type stomach
Definition
PA Axial
Term
IR Size for PA Oblique RAO
Definition
10 x 12
Lengthwise
Term
Recumbent
Adjust patient so that the sagittal plane passing midway between the vertebrae and lateral border of elevated side is centered to the IR
Definition
Part Position for PA Oblique, RAO
Term
CR for PA Oblique, RAO
Definition
Perpendicular to the center of the IR
Term
IR Size for AP Oblique LPO
Definition
10 x 12
Lengthwise
Term
part position for AP Oblique LPO
Definition
Supine
Align midline of IR with a sagittal plane passing midway between the vertebrae and the left lateral border of the abdomen
Center IR to a point midway between xiphoid process and lower rib margin
Adjust rotation to 30 to 60 degrees
Term
CR for AP Oblique LPO
Definition
Perpendicular to the center of the IR
Term
The AP oblique projection demonstrates the __ of the stomach
Definition
fundic portion
Term
IR Size for right lateral
Definition
10 x 12
Lengthwise
Term
part position for right lateral
Definition
Recumbent
Align the plane passing midway between the midcoronal plane and the anterior surface of the abdomen to the midline of the grid
Center the IR at the level of L1-L2 for recumbent position about 1-2 inches above the lower rib margin and L3 for the upright
Term
CR for right lateral
Definition
Perpendicular to the center of the IR
Term
a ___ shows the anterior and posterior aspects of the stomach, the pyloric canal, and the duodenal bulb
Definition
right lateral projection
Term
right lateral projection commonly affords the best image of the pyloric canal and the duodenal bulb in patients with a ___ habitus
Definition
hypersthenic
Term
IR size for AP stomach
Definition
10 x 12
Crosswise/Lengthwise
14 x 17
Lengthwise
Term
place patient in ___ position for demonstration of hiatal hernia
Definition
Trendelenberg
Term
Adjust the position of the patient so that the midline of the grid coincides with the midline of the body when a __ IR is used
Definition
14x17
Term
Adjust the position of the patient so that a sagittal plane passing midway between the midline and the lateral margin of the abdomen when a __ cm IR is used
Definition
10x12
Term
part position for 10x12 IR
Definition
Center the 10x12 IR at a level midway between the xiphoid process and the lower rib margin (L1-L2)
Term
part position for 14x17 IR
Definition
For the 14x17 IR, center it at the same level and adjust up or down slightly, depending on whether the diaphragm or small bowel needs to be seen
Term
structures shown on AP stomach
Definition
A well filled fundic portion and usually a double-contrast delineation of the body, pyloric portion, and duodenum
