Conficker worm invades U.K. hospital IT network
January 29, 2010 -- The Conficker virus infected approximately 120 computers in healthcare facilities run by the Mid Cheshire Hospitals NHS Foundation Trust in the U.K., according to a statement issued by the trust on January 28.
Perfusion CT handily distinguishes malignant neck nodes
January 25, 2010 -- In a new study from Poland, perfusion CT showed impressive accuracy for distinguishing benign from malignant lymph nodes in a study of squamous cell cancer patients with suspected metastases.
Medical images unlikely to change risky behavior, study shows
January 25, 2010 -- If you show an obese person a medical image of their plaque-clogged arteries, will it help motivate them to get more exercise? Not necessarily, although you might have better luck getting smokers to change their ways, according to a new review of literature from the Cochrane Collaboration.
Combined treatments improve inoperable cervical cancer outcomes
January 22, 2010 -- Providing both chemotherapy and radiation therapy to women with locally advanced cervical cancer improves their chances of survival, according to a new report from the Cochrane Collaboration.
Handheld devices show promise in emergency radiology
January 21, 2010 -- Handheld devices such as the iPod Touch may be suitable to review medical images in emergency radiology consultations, according to research published in the February issue of the American Journal of Roentgenology.
Italian researchers cut gadolinium dose -- as well as NSF risk
January 21, 2010 -- A half dose of a commercially available MRI contrast agent works as well as a full dose in patients with acute myocardial infarction, according to Italian researchers. The findings show it's possible to achieve shorter imaging times while protecting renally impaired cardiac patients at risk for nephrogenic systemic fibrosis (NSF).
Experience counts when reading contrast ultrasound liver images
January 19, 2010 -- Radiologists with experience reading contrast-enhanced ultrasound images have the upper hand over neophytes in characterizing malignant liver tumors, according to research published in the January issue of the Journal of Ultrasound in Medicine.
DOPA-PET/CT can alter therapy for neuroendocrine tumors
January 15, 2010 -- Swiss researchers have found that combined fluorine-18 dihydroxyphenylalanine (F-18 DOPA) contrast-enhanced PET/CT is "significantly superior" to DOPA-PET and contrast-enhanced CT in detecting neuroendocrine tumors.
CTA motion model aims to improve cardiac function analysis
January 11, 2010 -- Dutch researchers used an automated coronary artery motion model to analyze cardiac function from electrocardiogram-gated coronary CT angiography (CTA) data. The method promises to improve cardiac function analysis and reconstruction interval selection, and even provide new information on coronary artery motion at different heart rates.
DSCT edges out 64-slice CT in coronary artery imaging
January 8, 2010 -- Coronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.
