Negative oral contrast such as pineapple juice, [1] date syrup, ferumoxsil, Açaí juice and water are useful in decreasing T2 signal intensity, thus minimising signals from stomach and duodenum from interfering with signals from the biliary system. [6] MRCP makes use of heavily T2-weighted MRI pulse sequences.
A gastric emptying study is a nuclear medicine study which provides an assessment of the stomach's ability to empty.It may be used if there are complications after gastric surgery, for gastric reflux, or suspected gastroparesis amongst other indications. [1]
In children, abdominal x-ray is indicated in the acute setting: Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. [1] Foreign body in the alimentary tract; can be identified if it is radiodense. [1] Suspected abdominal mass [1]
Magnetic resonance elastography (MRE) is a form of elastography that specifically leverages MRI to quantify and subsequently map the mechanical properties (elasticity or stiffness) of soft tissue. First developed and described at Mayo Clinic by Muthupillai et al. in 1995, MRE has emerged as a powerful, non-invasive diagnostic tool, namely as an ...
This procedure is performed when intra-abdominal bleeding (hemoperitoneum), usually secondary to trauma, is suspected. [2]In a hemodynamically unstable patient with high-risk mechanism of injury, peritoneal lavage is a means of rapidly diagnosing intra-abdominal injury requiring laparotomy, but has largely been replaced in trauma care by the use of a focused assessment with sonography for ...
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.
X-ray of abdomen of a person with gastric outlet obstruction taken while on their side. There is a prominent gastric air bubble, gastric air-fluid level, and a dilated stomach with particulate matter within it. Specialty: General surgery, gastroenterology
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
