MRI helps identify mild cognitive impairment
October 5, 2010 -- Using advanced MRI and an artificial intelligence technique, researchers in Geneva, Switzerland, have identified a method that may help identify which individuals with mild cognitive impairment will continue to decline, according to a study published online and in the December issue of Radiology.
European MRI advocates gain victory on EMF Directive
October 5, 2010 -- A controversial European Union law that potentially could threaten the use of MRI in research laboratories and medical clinics will be overhauled, clearing the way for the technology to continue being used across Europe, according to an accord announced last week by EU officials.
New CAD for COPD parses disease type, severity
October 1, 2010 -- Dutch researchers are taking computer-aided detection (CAD) of the lungs beyond suspicious lung nodules and into the diagnosis of chronic obstructive pulmonary disease (COPD), aiming to identify the patients most likely to benefit from treatment.
U.K. survey finds satisfaction with PACS, but issues linger
September 29, 2010 -- While the overwhelming majority of U.K. clinicians are satisfied with PACS, a number of thorny issues still need to be addressed, according to research published in the September issue of the European Journal of Radiology.
CAD detects signs of emphysema on DR images
September 27, 2010 -- Most of the recent research on the use of computer-aided detection (CAD) software for analyzing digital radiography (DR) studies of the chest has focused on lung cancer. But Italian researchers this month in European Journal of Radiology report good performance of an emphysema CAD algorithm that they developed at their institution.
MRI helps visualize elbow ligaments in asymptomatic subjects
September 27, 2010 -- Using certain pulse sequences, conventional 1.5-tesla MRI can visualize elbow ligaments that previously were not consistently visible in asymptomatic subjects, helping to diagnose patients with elbow instability, according to a study in the October issue of Radiology.
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.
