MRI can be used to follow great vessel stents September 23, 2010 -- Using certain imaging sequences, MRI can be sufficient for the routine surveillance of certain great vessel stents commonly used to treat congenital heart defects in children and young adults, according to a study in the October issue of the American Journal of Roentgenology.
Accurate, fast soft-plaque measurement seen with coronary CTA September 21, 2010 -- Automated measurement of soft plaque in the heart using coronary CT angiography (CTA) was accurate compared to the gold-standard modality, intravascular ultrasound, and was far faster than manual methods, concluded a new report published online this month in Radiology.
Bundling of CAD software boosts lung lesion detection at CT September 21, 2010 -- Running CT lung images through multiple computer-aided detection (CAD) applications delivers better results than any single algorithm alone, researchers are finding. This phenomenon is unleashing a minitrend that may be discomforting to CAD developers concerned about the success of their systems.
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.
