Cholecystokinin (CCK) Duct of Wirsung is what structure? pancreatic duct broadest portion of gallbladder: fundus enlarged chamber in distal aspect of common bile duct: hepatopancreatic ampulla series of mucosal folds in cystic duct: spiral valve circular muscle fibers adjacent to duodenal papilla: hepatopancreatic sphincter A protrusion into the duodenum: duodenal papilla duct connected directly to gallbladder: cystic duct narrowest portion of gallbladder: (neck or body?) neck middle aspect of gallbladder: (neck or body?) body The condition of gallstones is called? cholelithiasis which one is NOT a function of the GI system: a. intake and digestion of food b. absorption of nutrients c. production of hormones d. elimination of waste products c. production of hormones
T/F the numerous mucosal folds found in the small bowel are called rugae False, in the stomach which aspect of the stomach fills with air when the patient is prone during a double contrast UGI Fundus T/F the lateral margin of the stomach is called the lesser curvature False, greater curvature to which aspect of the stomach does barium gravitate to when the pt is in a supine position fundus which two structures create the romance of the abdomen head of pancreas and the C-loop of the duodenum Opening leaving the stomach: pyloric orifice Found along superior aspect of fundus: cardiac notch most posterior portion of stomach: Fundus of stomach Ascending portion of duodenum: fourth portion of duodenum rugae is what aspect of the upper GI? mucousal folds middle aspect of the stomach body of stomach opening between esophagus and stomach esophagogastric junction Indentation found along lesser curvature angular notch Horizontal portion of duodenum third portion of duodenum the act of chewing is called
mastication which term describes food after it enters the stomach and is mixed with gastric secretions chyme A churning or mixing activity present in the small intestine is called: rhythmic segmentation nutrients that are not digested vitamins what body habitus has a high and transverse stomach, duodenal bulb at the v ertebral level of T11-T Hypersthenic patient what body habitus includes the low and vertical stomach with the duodenal bulb at the level of L3-L Hyposthenic/Asthenic most common radiopaque contrast medium used in the GI system barium sulfate which of the following conditions may prevent the use of water-soluble contrast agents for a geriatric patient? a. bowel obstruction b. pre-surgical imaging c. dehydration d. perforated ulcer c. dehydration T/F water soluble contrast agents pass through the Gi tracts faster than barium sulfate True T/F digital fluoroscopy does not require the use of IR cassettes True cardinal principle most effective in reducing exposure to the technologist during fluoro is: Distance older term for GERD esophageal reflux a large outpouching of the mid-to-upper esophagus is termed: a. Zenker's diverticulum
which UGI position best demonstrates a possible gastric diverticulum in the posterior wall of the fundus of the stomach Right lateral an UGI series is performed on an asthenic patient. a radiograph of the RAO shows that the duodenal bulb and C-loop are not in profile. The tech rotated the patient 70 degrees. What modification can be made on the repeat exposure decrease patient rotation to 40 degrees for an astenic patient a radiograph taken during a double contrast UGI demonstrates that the fundus is barium filled and the body is air filled. What position does this radiograph represent AP performed recumbent a patient with clinical history of cirrhosis of the liver with acute GI bleeding comes to the radiology department. what may be the most likely reason that and esophagogram was ordered for this pt rule out esophageal varices We have an expert-written solution to this problem! during an esophagogram the radiologist asks the pt to try to bear down as is having a bowel movement. What is the maneuver called and why did the radiologist make the request? Valsalva maneuver, requested to rule out esophageal reflux during an UGI the radiologist reports that she see a "lucent-halo" sign in the duodenum. What form of pathology did the radiologist see? an ulcer a radiograph of an UGI is no labeled correctly, the technologist is unsure of what position was performed. a double contrast GI study was completed with all position recumbent. barium in the fundus and air in the body and pylorus and the duodenal bulb in profile LPO recumbent shielding device best reduces exposure to the lower torso of fluoroscopist? a. lead drape b. bucky slot shield c. lead gloves d. grid b. bucky slot shield
during an esophagogram, the radiologist remarks that Schatzki's ring is present. Which condition or disease process is indicated by the presence of this radiographic sign? Sliding hiatal hernia a patient comes to the radiology dept with a clinical history of a possible trichobezoar. what is a trichobezoar and which procedure will best diagnose is mass of hair trapped in the stomach. UGI study may be perfomed to diagnose this condition. what type of radiolucent contrast medium is most commonly used for double-contrast GI studies? carbon dioxide (calcium or magnesium citrate) We have an expert-written solution to this problem! a. what is the ratio of barium to water for a thick mixture of barium sulfate? b. what is the ratio for a thin barium mixture? a. 3 to 4 barium parts to 1 water parts b. 1 barium part to 1 part water during an upper GI, when should a water-soluble contrast medium be used rather than barium sulfate? when there's a possibility of the contrast media may spill into the peritoneum protective aprons of what lead equivalency must be worn during flouroscopy? a. 1.0 mm Pb/Eq b. 0.50 mm Pb/Eq c. 0.25 mm Pb/Eq d. 0.15 mm Pb/Eq b. 0.50 mm Pb/Eq what can be added to barium sulfate and swallowed to detect a radiolucent foreign body lodged in the esophagus? shredded cotton or marshmallows Why is an RAO position preferred rather than an LAO during and esophagogram? bc an RAO places the esophagus b/w the heart and vertebral better than an LAO which of the following technical/positioning factors does not apply to an water soluble oral contrast media upper GI study? a. 125 kVp b. exposure made on expiration
