Term
Which structure forms the mesentery and omenta folds?
Definition
Peritoneum
Term
Which organ's blood is supplied by the portal vein?
Definition
Liver
Term
Which duct is formed by the merging of the right and left hepatic ducts?
Definition
Common hepatic
Term
Which duct is formed by the union of the cystic duct with the common hepatic duct?
Definition
Common bile
Term
Where do the pancreatic and common bile ducts terminate?
Definition
Duodenum
Term
Which duct connects the gallbladder to the common hepatic duct?
Definition
Cystic
Term
Which three projections usually comprise the acute abdominal series for ambulatory patients?
Definition
Supine KUB, AP upright abdomen, and PA chest
Term
To which level of the patient should the IR be centered for the KUB?
Definition
Iliac crests
Term
For the AP upright abdomen radiograph of an adult of average size, why should the IR be slightly raised above the centering level used for the supine KUB radiograph?
Definition
To include the diaphragm
Term
For the KUB radiograph, when should respiration be suspended, and what effect will that have on the patient?
Definition
On full expiration; elevate the diaphragm
Term
Why is it desirable to include the diaphragm in the upright abdomen radiograph?
Definition
To demonstrate free air in the abdomen
Term
Which of the following guidelines is not necessary to follow when deciding whether to use gonadal shielding for the KUB radiograph?
Definition
The permission to use gonadal shielding is granted by the patient.
Term
Which projection should be used to demonstrate free air within the abdominal cavity when the patient is unable to stand for an upright abdomen radiograph?
Definition
AP projection, left lateral decubitus position
Term
Which projection does not demonstrate free air levels within the abdomen?
Definition
AP projection with the patient supine
Term
What is the major advantage of the PA projection of the abdomen over the AP projection of the abdomen?
Definition
The PA projection reduces the exposure dose to the gonads.
Term
Which radiographic position of the abdomen requires that the patient be placed in the lateral recumbent position on his or her left side and that the central ray be directed along the midsagittal plane, entering the anterior surface of the patient's abdomen at the level of the iliac crests?
Definition
Left Lateral Decubitus
Term
Which radiographic position of the abdomen requires that the patient be supine and that the central ray be directed to a lateral side of the patient, entering slighly anterior to the midcoronal plane?
Definition
Dorsal Decubitus
Term
Which radiographic position of the abdomen requires that the patient be placed in the lateral recumbent position on his or her left side, that the IR be placed under the patient and centered to the abdomen at the level of the iliac crests, and that the central ray be directed to enter the right side of the patient slightly anterior to the midcoronal plane?
Definition
Left Lateral
Term
The lateral projection with the patient placed in the dorsal decubitus position, the left lateral projection, and the left lateral decubitus position of the abdomen all require which of the following?
Definition
The patient should suspend respiration after expiration
Term
For the lateral projection with the patient placed in the dorsal decubitus position, where should the central ray enter the patient?
Definition
2 inches(5cm) anterior to the midcoronal plane and 2 inches above the level of the iliac crests.
Term
For the lateral projection with the patient placed in the dorsal decubitus position, which procedure should be performed to ensure that the entire abdomen is included on the radiograph?
Definition
Use support cushions to elevate the patient
Term
Which structures should be examined to see whether the patient was rotated for a lateral projection of the abdomen?
Definition
Pelvis and lumbar vertebrae
Term
Which imaging procedure should be part of the OCG examination?
Definition
Use short exposure times and short scale contrast.
Term
For OCG procedures, when should respiration be suspended, and what effect will this have on the position of the gallbladder?
Definition
On full expiration; elevate the gallbladder
Term
Which procedure should be performed when the patient is rotated from a prone position to the LAO position for an OCG examination?
Definition
Place a radiolucent foam wedge under the abdomen.
Term
For an OCG examination of a patient of average build, where should the IR be centered?
Definition
At the level of the 9th rib on the right side.
Term
Compared to IR placement for a patient of average build, how should the IR be moved for an OCG examination of a hypersthenic patient?
Definition
Higher
Term
Which procedure should be performed for a subsequent PA projection radiograph when the initial PA projection radiograph demonstrates the shadow of the gallbladder superimposed by ribs?
Definition
Make the exposure after full inspiration
Term
Which procedure most effectively separates the shadows of the gallbladder and vertebrae?
Definition
Rotate the patient into an oblique position
Term
Which projection best demonstrates the stratification of gallstones?
Definition
AP projection, right lateral decubitus position
Term
Which procedure best demonstrates a gallbladder that is situated in the iliac fossa?
Definition
Place the patient in the supine position
Term
Why should patients be scheduled for OCG examinations in the early morning?
Definition
Prolonged fasting causes the formation of gas
Term
Which projection places the gallbladder closest to the IR?
Definition
PA projection
Term
Which procedure should not be performed as part of patient preparation for the OCG examiniation?
Definition
Instruct the patient to take laxatives within 24 hours before swallowing oral contrast medium.
Term
Which diagnostic modality is most often used when an OCG examination does not adequately demonstrate a gallbladder?
Definition
Sonography
Term
Which projection produces a foreshortened image of the gallbladder?
Definition
PA projection with the patient prone
Term
Which of the following projections does not increase the separation of the gallbladder shadow from the vertebrae?
Definition
PA projection
Term
Which procedure should be performed for the left PA oblique projection that is part of an OCG examination?
Definition
Rotate thin patients more than large patients
Term
which procedure should be performed when using the right lateral decubitus position that is part of an OCG examination?
Definition
Place the patient on a radiolucent cushion
Term
What is an advantage to using the right lateral decubitus position for demonstration of the gallbladder?
Definition
This position enables the gallbladder to gravitate toward the dependent right side of the abdomen.
Term
Which two projections best visualize the stratification of gallstones?
Definition
AP(right lateral decubitus position) and prone PA projections
Term
Which projection is generally not used as part of the OCG examination?
Definition
Lateral projection, dorsal decubitus position
Term
Which projection of the gallbladder can be performed only with a horizontally directed central ray?
Definition
AP projection,right lateral decubitus position
