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. Read More

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. Read More

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. Read More

Minimal-prep VC gets new boost from dual-energy CT
July 21, 2010 -- A new dual-energy CT electronic cleansing technique thoroughly outperformed an advanced single-source CT cleansing method in virtual colonoscopy in a recent study. The technique eliminated many common artifacts that have plagued investigational electronic cleansing techniques. Read More

Database identifies radiation therapy toxicities in kids
July 15, 2010 -- Since 2004, radiation oncologists in Germany have been submitting information about pediatric radiotherapy treatments to a study trial center database. Now an analysis of acute toxicities from this database of more than 1,000 patients has been recently published in Radiotherapy & Oncology, providing an overview of the pattern of acute toxicities of irradiated organs.

CO₂ volumes higher than previous reports in VC
July 6, 2010 -- Using more CO₂ to insufflate the colon during virtual colonoscopy doesn't produce better distention, but patients with ileocecal valve incompetence -- most patients presenting for screening -- require more insufflation, say researchers from Ireland. Read More

PET/CT beats CT in NSCLC staging, but both have limitations
July 2, 2010 -- While no imaging or invasive procedure is foolproof for staging non-small cell lung cancer (NSCLC), Danish researchers have found that PET/CT is more accurate than CT alone, though both modalities had a tendency to understage and overstage the cancer. Read More

MRI can identify osteoarthritis risk factors 10 years early
June 30, 2010 -- MRI can identify risk factors in patients with subacute knee symptoms that can lead to localized knee osteoarthritis 10 years later, according to a study published online in Radiology. Read More

CT-based Crohn's diagnosis takes aim at endoscopy
June 29, 2010 -- GENEVA - Japanese researchers hope to supplant the invasive and time-consuming process of diagnosing Crohn's disease with a CT technique that is unaffected by intestinal stenosis and other impediments to conventional endoscopic evaluation. Read More
