By combining different CT views, radiologists can better evaluate the GI tract
May 04, 2006Combined evaluation of transverse images-horizontal slices of a standing body-and multiplanar coronal reformats-vertical slices from head to foot-from CT scans give radiologists more information about the GI tract to better diagnose problems, according to a new study by researchers from Emory University School of Medicine in Atlanta, GA.
For the study, the researchers analyzed routine abdomen-pelvis CT studies from 50 patients. The researchers found that with simultaneous review of transverse and coronal images, additional findings were recorded in 10 studies and the doctors had a higher confidence in interpreting 18 of the studies. All together, 281 lesions were detected on simultaneous review of coronal and transverse images, whereas 259 lesions were detected on transverse images alone.
To get these coronal reformats, data from a series of contiguous transverse scan images are recombined, manipulated or processed by the CT technologist at a computer workstation to produce images in the coronal plane.
"If radiologists can detect more findings using both transverse images and coronal reformats as our study suggests, it could definitely benefit patients. In addition, we are generating these coronal reformats from already acquired transverse images, so there is no extra radiation exposure to the patients. These images can be reconstructed from the transverse images at the CT console by the CT technologist in less than a minute," said Sunit Sebastian, MD, lead author of the study.
The full results of the study will be presented on May 4, 2006 during the American Roentgen Ray Society Annual Meeting in Vancouver, BC.

GI Tract Current Events and GI Tract News RSSIrritable Bowel Syndrome patients not at more risk of colon cancer, polyps
Patients with irritable bowel syndrome are at no greater risk of having polyps, colon cancer or inflammatory bowel diseases than healthy people undergoing colonoscopies, according to new research published in the American Journal of Gastroenterology.
Polymer therapeutic protects gut from radiation damage, infection after cancer treatment
A non-absorbed, oral co-polymer therapy under development by Midway Pharmaceuticals demonstrated the ability to protect against damage to healthy gastrointestinal tissues and to prevent lethal bacterial infections in animal models of radiation damage.
Largest gene study of childhood IBD identifies 5 new genes
In the largest, most comprehensive genetic analysis of childhood-onset inflammatory bowel disease (IBD), an international research team has identified five new gene regions, including one involved in a biological pathway that helps drive the painful inflammation of the digestive tract that characterizes the disease.
Many patients with sleep apnea also suffer from GI tract conditions
Patients who suffer from obstructive sleep apnea (OSA) also tend to have additional gastrointestinal (GI) tract conditions, such as gastric reflux and hiatal hernia, which form at the opening in your diaphragm where your food pipe (esophagus) joins your stomach.
Sticky protein helps reinforce fragile muscle membranes
A new study by scientists at the University of Iowa shows why muscle membranes don't rupture when healthy people exercise.
Electronic Pill Shows Its Smarts by Measuring pH Levels in Digestive Tract
An electronic diagnostic tool called the SmartPill is swallowed by patients in order to take measurements as it travels through the gastrointestinal tract.
Improved DNA stool test could detect digestive cancers in multiple organs
Mayo Clinic researchers have demonstrated that a noninvasive screening test can detect not only colorectal cancer but also the common cancers above the colon -- including pancreas, stomach, biliary and esophageal cancers.
A breakthrough in diagnosis of enteric lesions
Capsule endoscopy (CE), which is virtually a micro-camera, is a revolutionary diagnostic tool in diagnosing small bowel diseases, and CE can obtain 40-60 thousand images of the GI tract, though the number of the images for the lesions is smaller than 500 in most of the patients.
Chronic inflammation can help nurture skin cancer, study shows
Inflammation, a frontline defense against infection or disease, can help nurture skin cancer, researchers have found.
Mayo Clinic physicians estimate new, tiny, super-sensitive probe could cut colon polyp removal in half
Based on results of a landmark study, researchers at Mayo Clinic's Florida campus see a future in which virtual biopsies will eliminate the need to remove colon polyps that are not cancerous or will not morph into the disease.
