CAD algorithm spots acute intracranial hemorrhage September 20, 2010 -- In stroke treatment, time is brain, as they say, but the timely detection of acute intracranial hemorrhage can be difficult when dealing with subcentimeter lesions or inexperienced readers. A new computer-aided detection (CAD) system designed to detect blood clots in the brain could be a welcome addition.
PET/CT detects early efficacy of chemo drug in NSCLC patients September 17, 2010 -- Dutch researchers have found that FDG-PET/CT can identify early response to preoperative chemotherapy with erlotinib in most patients with non-small cell lung cancer (NSCLC), according to a study in the September issue of the Journal of Nuclear Medicine.
Advanced VC tool serves up polyp locations for colonoscopy September 17, 2010 -- Large polyps found at virtual colonoscopy are referred to optical colonoscopy for removal, and that's generally the end of the story. But VC-detected polyps can't always be found quickly and easily at colonoscopy, so an automated method of finding them might be just what the gastroenterologist ordered.
French government mulls nationwide PACS initiative September 14, 2010 -- France may be the latest European nation to pursue a large-scale PACS initiative if a digital image management proposal is adopted by the French government. If approved, the plan would implement a countrywide framework for storing medical image data, encompassing national, regional, and local levels.
3D TEE bests 2D TEE in mitral regurgitation grading September 10, 2010 -- 3D transesophageal echocardiography (TEE) is superior to 2D TEE for quantifying the severity of mitral regurgitation, according to researchers from Leiden University Medical Center in Leiden, the Netherlands.
Study finds VC cost-effective if tiny polyps are ignored September 9, 2010 -- Virtual colonoscopy is cost-effective for colorectal cancer screening, assuming that only patients with polyps 6 mm or larger are referred for polypectomy, a new French study has concluded. Removing the smallest lesions is not only prohibitively expensive, the yield in terms of additional cancer is minimal.
Advanced CT may have role in noncalcified plaque assessment September 8, 2010 -- Advanced MDCT scanning may be ready to play an important role in assessing noncalcified coronary artery plaque, say German researchers, who used a 256-detector-row scanner and plaque-volume measurement software to compare interobserver variability in patients with different types of plaque.
CAD labels abdominal vessels with improved accuracy September 2, 2010 -- A new computer-aided detection (CAD) algorithm automatically labels abdominal arteries extracted from CT images. The work-in-progress system is more accurate and less dependent on error-prone features than previous CAD schemes, say researchers from Nagoya, Japan.
Cardiac MRI shows how triathletes' hearts adapt September 1, 2010 -- With the help of 1.5-tesla cardiac MRI, German researchers have found that the human heart adapts to triathlon training by developing greater muscle mass and wall thickness, as well as larger left atria and larger right and left ventricles, according to a study to be published in the October issue of Radiology.
Contrast MRI visualizes bowel damage caused by celiac disease September 1, 2010 -- Contrast-enhanced MRI dynamic evaluation of the bowel wall can effectively visualize inflammation caused by celiac disease, aiding the assessment of patients with this condition, according to a study in the September issue of Radiology.
