A CT scan image showing a ruptured abdominal aortic aneurysm. CT Scan of 11 cm Wilms' tumor of right kidney in 13-month-old patient. Computed tomography of the abdomen and pelvis is an application of computed tomography (CT) and is a sensitive method for diagnosis of abdominal diseases. It is used frequently to determine stage of cancer and to ...
Computed tomography enterography (CT enterography, CTE) is a medical imaging technique which uses computed tomography scanner and contrast media to examine the small bowel. [1] It was first introduced by Raptopoulos et al. in 1997. [ 2 ]
Virtual colonoscopy (VC, also called CT colonography or CT pneumocolon) is the use of CT scanning or magnetic resonance imaging (MRI) to produce two- and three-dimensional images of the colon (large intestine), from the lowest part, the rectum, to the lower end of the small intestine, and to display the images on an electronic display device.
The colon cut-off sign is a radiographic finding seen on abdominal radiographs and computed tomography scans. It is characterized by a marked dilatation of the transverse colon, with an abrupt transition to collapsed distal colon, particularly the splenic flexure. [1] This sign is indicative of underlying pathology, most commonly acute ...
A lower gastrointestinal series is a medical procedure used to examine and diagnose problems with the human colon of the large intestine. Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum.
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. [2] However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. [1] Computed tomography provides an overall better surgical strategy planning, and possibly fewer unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. [2]
In children, ultrasound is preferred while in adults a CT scan is preferred. [1] Intussusception is an emergency requiring rapid treatment. [1] Treatment in children is typically by an enema with surgery used if this is not successful. [1] Dexamethasone may decrease the risk of another episode. [2]
