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.
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.
Colonoscopies are often used to diagnose colon polyp and colon cancer, [15] but are also frequently used to diagnose inflammatory bowel disease. [16] [17] Another common indication for colonoscopy is the investigation of iron deficiency with or without anaemia. The examination of the colon, to rule out a lesion contributing to blood loss, along ...
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Colonic polypectomy is the removal of colorectal polyps in order to prevent them from turning cancerous.. Method of removing a polyp with a snare. Gastrointestinal polyps can be removed endoscopically through colonoscopy or esophagogastroduodenoscopy, or surgically if the polyp is too large to be removed endoscopically.
Perhaps most important, current whole-body MRI does not replace more established surveillance tools like colonoscopy, Pap smear or mammography for cancer detection.
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization
Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
