Report: Growth will resume in European digital x-ray markets
August 13, 2010 -- Growth is expected to resume this year in the European market for digital radiography and computed radiography after a slowdown in 2009, according to market research firm Frost & Sullivan.
FDG-PET before RT can modify planned NSCLC treatment
August 11, 2010 -- FDG-PET scans of non-small cell lung cancer (NSCLC) patients reviewed before radiation therapy (RT) may lead to significant changes in treatment strategy and radiation therapy planning, according to a study in the August issue of the American Journal of Roentgenology.
Combined PET/CT CAD improves lung nodule detection
August 6, 2010 -- Researchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.
Enhanced reference standard boosts CTA accuracy
August 4, 2010 -- Borrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.
Constipated kids don't need abdominal x-rays
August 4, 2010 -- The practice of ordering an abdominal x-ray exam for constipated children to assess the presence of retained feces or to confirm a diagnosis made during a physical exam should be stopped, as the procedure is of limited value, according to an analysis published online in Pediatric Radiology.
Simultaneous PET/MRI creates diagnostic-quality images
August 3, 2010 -- Structural, functional, and molecular imaging of patients with brain tumors is feasible with diagnostic imaging quality using simultaneous hybrid PET/MR image acquisition, according to a study in the August issue of the Journal of Nuclear Medicine.
Supersized CONFIRM trial tackles coronary CTA and mortality
July 30, 2010 -- In a study that probes what may be the largest database of detailed coronary CT angiography (CTA) results assembled to date, New York City researchers found an integral association between coronary artery disease and mortality at coronary CTA in patients without known heart disease.
Contrast US processing tool shows malignant liver lesions
July 30, 2010 -- Swiss researchers have developed a real-time parametric imaging technique for distinguishing benign from malignant liver lesions easily and noninvasively using contrast-enhanced ultrasound. In its first clinical run, the method delivered high sensitivity and specificity in a patient cohort.
Study finds clinical niche for DR tomo in pulmonary lesions
July 28, 2010 -- Imaging researchers have long known that chest tomosynthesis is more sensitive than conventional x-ray for detecting malignant pulmonary lesions, while producing lower radiation dose than CT. Now, they are zeroing in on a precise role for this unique technology.
Myocardial echo bests SPECT in assessing hibernating myocardium
July 26, 2010 -- Myocardial contrast echocardiography can outperform SPECT for assessing hibernating myocardium in ischemic cardiomyopathy, London researchers report in the Journal of the American Society of Echocardiography.
