Presentation on theme: "Imaging the GI Tract: Plain Film"— Presentation transcript:

1 Imaging the GI Tract: Plain Film
Anteroposterior View of the Abdomen With Patient Standing Look for the location of the gas bubble in the stomach How do we know the patient is standing?

2 Air bubble in fundus of stomach Liver outline T12 Vertebrae L1

3 What Else Can We See on a Plain Film?
Gas! air in stomach air in transverse colon

4 Barium Contrast Study Of The Esophagus
Vertebral column A lateral view of the upper GI tract following a barium swallow This image demonstrates normal anatomy of the esophagus Esophagus Phrenic Ampulla (only seen radiologically) Diaphragm Stomach

5 Barium Contrast Study of the Stomach
fundus lesser curvature duodenal cap pylorus pyloric antrum peristalsis in action! rugae greater curvature duodenum

6 More of the Same... rugae gallbladder duodenum gas bubble in
stomach fundus jejunum greater curvature body

7 Now Let's Start From the Other End splenic flexure A barium enema
hepatic flexure haustra ascending colon transverse colon sigmoid colon descending colon rectum

8 A Double Contrast Study
The bowel is distended with air, and a small volume of barium is used to coat the mucosa How has the patient been positioned?

9 Celiac Trunk Arteriogram
hepatic a. splenic artery left gastric a. right gastric a. left gastro- omental artery celiac trunk gastroduodenal a. catheter

10 Superior Mesenteric Arteriogram
middle colic a. right colic a. superior mesenteric a. arteries to jejunum ileocolic a. arteries to ileum catheter

11 Inferior Mesenteric Arteriogram
renal pelvis inferior mesenteric a. superior rectal a. left colic a. catheter sigmoid arteries lead shield

12 Percutaneous Transhepatic Cholangiography
Water-soluble contrast material is injected directly into the liver via a fine needle introduced through the skin gallbladder

13 More of the Same contrast in fundus of gallbladder

14 Postoperative Cholangiogram
Water-soluble contrast was injected into the biliary system via a tube left in place following removal of the gallbladder (cholecystectomy) right hepatic duct left hepatic duct common hepatic duct common bile duct pancreatic duct duodenum

15 A-P View of the Lumbar Spine
How many lumbar vertebrae are there? 1 What are the main regional characteristics of these vertebrae? 2 Large bodies 3 No ribs 4 Stout transverse processes 5

16 12th rib 12th thoracic vertebra body of L1 superior articular process of L2 transverse process of L2 pedicles of L3 inferior articular process of L4 spine of L5 lumbosacral joint

17 Lateral View of the Lumbar Spine pedicle of L2 body of L2
inferior articular process of L4 superior articular process of L5 lumbosacral joint sacrum
