Gastrointestinal Radiology

Radiology and Gastrointestinal Disorders

• Closed loop obstruction can occur due to volvulus or adynamic ileus, resulting in uniformly dilated intestines that resolve within 36 to 48 hours.
• Sigmoid volvulus involves the sigmoid colon twisting on itself, forming an inverted "U" shape, leading to a sausage or balloon-like appearance.
• Cecal volvulus involves the cecum twisting around its mesentery, causing distention and shifting within the abdomen.
• Pneumoperitoneum, the presence of air or gas in the peritoneal cavity, can be revealed through an upright chest radiograph.
• Barium enema procedures involve specific dietary preparations and positioning to visualize the colon.
• Different projections and positions are used to visualize specific segments of the colon during barium enema procedures.
• Various gastrointestinal disorders, such as Crohn's disease, ulcerative colitis, malabsorption syndrome, diverticular disease, Meckel's diverticulum, and others, can be diagnosed through imaging.
• Key details about polyps, colon cancer, peritonitis, Hirschsprung's disease, and imperforate anus are outlined.
• Different radiographic examinations, such as cholecystography, cholangiogram, choleography, and cholecystocholangiogram, are used to visualize the gallbladder and bile ducts.
• Surgical and postoperative procedures, such as laparoscopic cholecystectomy, operative cholangiography, T-tube cholangiography, and endoscopic retrograde cholangiopancreatography, are described.
• Pancreatitis, cholecystitis, cholelithiasis, cirrhosis of the liver, hepatocellular carcinoma, and pancreatic cancer are discussed as possible conditions visualized through radiographic imaging.
• The most common type of pancreatic cancer, pancreatic ductal adenocarcinoma, originates in the cells lining the pancreatic ducts.
