Reduced-voltage cardiac CT works fine -- if you know the rules
May 19, 2010 -- SAN FRANCISCO - Backed by growing clinical evidence, radiologists should step up to the plate and cut the tube voltage in their cardiovascular CT protocols. But getting the benefits without the pitfalls means paying attention to some technical considerations.
320-slice CT identifies vocal cord dysfunction in asthma patients
May 19, 2010 -- NEW ORLEANS - Researchers from Australia at this week's American Thoracic Society meeting suggested that dynamic 320-slice CT can noninvasively pinpoint vocal cord dysfunction among patients with asthma.
Imorgon aims to carve out ultrasound PACS niche
May 19, 2010 -- Dissatisfaction with ultrasound functionality on PACS workstations has been an age-old complaint, leading many institutions to install separate ultrasound PACS to meet their needs.

MBIR aims to outshine ASIR for sharpness, CT dose reduction
May 18, 2010 -- Recent studies indicate that CT scanning with an adaptive statistical iterative reconstruction (ASIR) algorithm offers better image quality at a lower radiation dose. But a new algorithm, called model-based iterative reconstruction (MBIR), could be even better, according to a presentation today at the International Society for Computed Tomography meeting.

Study: Does radiation increase breast cancer risk?
May 18, 2010 -- Radiation exposure can alter the environment surrounding breast tissue cells so that future cells may become cancerous, according to a new study published in the online journal Breast Cancer Research.
Teens contribute to radiology-related research
May 17, 2010 -- Today's teens may have a reputation as slackers addicted to video games and iPhones, but teen researchers are making a difference in medical imaging with research studies presented at medical conferences in the past month, including one at this week's American Thoracic Society meeting in New Orleans.
Virtual colonoscopy adds to number of people getting screened
May 17, 2010 -- The impact of screening virtual colonoscopy in an area where the procedure is fully reimbursable appears not to have affected endoscopic procedures but, instead, has led to an increase in the number of optical colonoscopies performed, say researchers from the University of Wisconsin.
JACC special issue tackles radiation dose in cardiac imaging
May 14, 2010 -- A series of editorials in this month's Journal of the American College of Cardiology examines radiation risk from cardiac imaging exams, and asks if the benefits of imaging have been understated in the risk-benefit equation to the detriment of patient care.
