Question | Answer |
---|---|
what is the UGI a study of | distal esophagus, stomach, and duodenum |
what would be a contraindication for the UGI study | mainly type of contrast used |
what is the goal of patient prep for a upper GI series | to arrive with an empty stomach |
when should exam be scheduled | during morning hours |
_______after midnight | NPO |
how long should food and water be held for prior to this exam | at least 8 hrs |
what are additional instructions for the pt prior to the exam | no smoking or chewing gum |
true or false there is no need to warn the pt about the length of the exam | false |
what is the Kv range for single contrast | 100-110 |
what is the Kv range for double contrast | 90-100 |
what is the Kv range for iodine | 80-90 |
are short or long exposure time needed to control peristaltic motion | short |
what will happen if the kV is to low on contrast filled structures | will not provide visibility of the mucosa of the esophagus stomach and duodenum |
upper GI AP projection - what is the CR | L1- L2 1-2" above crest |
upper GI AP projection- what is the structure shown | AP projection of the stomach with well filled funds portion duodenum and jejunum |
upper GI AP projection - where does the sagittal plane pass | midway b/t midline and left lateral margin of the abdomen (10x12) |
upper GI PA projection - (prone) what is the CR | 1-2" above the the lower rib margin @ the level of L1-L2 1-2" above crest |
upper GI PA projection - what is the structure shown | contour of barium filled stomach DUODENAL BULB |
upper GI PA projection -what happens to the stomach | it spreads |
upper GI PA projection - what is the upright used for | to show the position of the stomach |
what is an alternative upper GI AP projection | trendelenburg (head down) |
where is crest located | L4 |
upper GI PA projection - (upright ) what is the CR | 3-6" lower than L1-L2 |
what does a full trendelenburg show | hiatal hernia |
upper GI PA projection - where does the midline of the Grid coincide with | sagittal plane passing halfway b/t vertebral column and left lateral boarders for the abdomen |
upper GI PA projection - oblique RAO whah the CR | perpendicular centered 1-2" above lower rib margin at the level of L1- L2 |
upper GI PA projection - oblique RAO whats the structure shown | entire duodenal loop best image of the pyloric canal |
upper GI PA projection - oblique RAO what the degree of body rotation | 40-70º |
upper GI PA projection - oblique RAO what the tube angulation | 0º |
upper GI AP projection what the angulation | 0º |
upper GI PA projection - oblique RAO what the degree of body rotation for hypersthenic | 40-70º on the greater degree of rotation |
upper GI PA projection - oblique RAO whats the pt position key points | rest head on right cheek raise left side of body and support it by resting on the left forearm and flex knees |
upper GI PA projection - oblique RAO what is the same plane as midline of the grid | vertebral column and the lateral boarder of upside is the same plane |
UGI AP oblique LPO positon what is the CR | L1-L2 level of the body of the stomach which would be at the point midway b/t xiphoid process Lowe margins of the ribs |
UGI AP oblique LPO positon - what is the SS | fund portion of the stomach bc of gravity |
UGI AP oblique LPO positon what is the body rotation | 30-60– but 45º for average pt |
UGI AP oblique LPO position what is the angle | 0º |
UGI AP oblique LPO positon | rotate 45º flex right knee and and rotate toward toward left to support abduct left arm away from body sagittal plane passing midway b/t vertebrae and left margins of the ab skimming light must be seen on down side |
which body position show better barium filled pyloric canal duodenal bulb | RAO |
UGI right lateral why is the right done | to show right retrogastric space duodenal loop duodenojejunal juntion |
UGI right lateral what the CR | perpendicular entering level of L1 L2 )1-2" above crest |
UGI right lateral what the SS | anterior and posterior of the stomach pyloric canal duodenal bulb |
what the best view for pt with hypersthenic habits | UGI right lateral |
what the length of the adult sm intestine | 22ft |
where does the sm intestine extend from | pyloric sphincter of the stomach to the ileocecal valve (Lg intestine) |
what occurs at the sm intestine | digestion and aborstion |
what are the 3 parts the sm intestine is divided into | duodenum jejunum ileum |
what is the length of the duodenum | 8-10" |
what is the widest portion of the sm intestine | duodenum |
where doest the duodenum begin and whats its shape | at the pylorus, c shape |
there are 4 regions of the duodenum name/or describe them | 1st duodenal bulb 2nd 3-4 " long 3rd. 2.5" long 4th. joins jejunum at sharp curve called the duodenojejunal flexure and supported by the ligaments of treitz |

what appearance does the jejunum have when filled with positive and negative contrast | coiled spring or stack of coins |
what portion if the sm intestine is the ileum | lower 3/5 or last portion |
what appearance does the ileum have when filled with barium | smooth |
what is characterized as the final portion of the ileum | ileocecal valve |
what joins the bowel joints and the large intestine | ileocecal valve |
