Heart societies issue new guidelines on cardiac cath May 10, 2012 -- A report issued on Wednesday by the American College of Cardiology Foundation and several other medical societies offers detailed criteria for determining when invasive cardiac catheterization is a reasonable option for evaluating patients for heart disease.
ACR, ASTRO comment on proposed stage 2 MU rules May 10, 2012 -- May 7 was the deadline to comment on the second stage of achieving meaningful use (MU), the U.S. government's initiative promoting conversion to healthcare IT. The deadline triggered a flurry of activity from interested parties, including the American College of Radiology (ACR) and the American Society for Radiation Oncology (ASTRO).
FDA targets vendors in push to trim pediatric radiation dose May 9, 2012 -- The U.S. Food and Drug Administration has raised the ante in its drive to reduce pediatric radiation dose, launching a new program that will require manufacturers to consider the safety of children when designing new x-ray imaging devices. Devices that do not comply with the program may have to carry warning labels advising against their use in children.
Low-dose CT's bright future, troubled present May 9, 2012 -- The task at hand in CT radiation dose reduction is pretty straightforward: Record the dose, establish best practices for using it, and then use the right dose for every scan. But in reality these goals are so complex as to be nearly impossible, said Dr. R. Paul Guillerman of Texas Children's Hospital in Houston.
Radiologists could be key in identifying signs of elder abuse May 9, 2012 -- A radiologist-led team from Toronto has identified a gestalt of injuries and surrounding social context common to most cases of physical abuse of the elderly. The group believes this could be a guide to identifying victims of elder abuse, much as a pediatric radiologist defined the signs of shaken-baby syndrome in the 1940s.
In an emergency, iPad can handle pulmonary embolism May 8, 2012 -- When pulmonary embolism (PE) is suspected in an emergency room patient, there's no time to waste. Offering equivalent diagnostic performance to a PACS workstation, Apple's iPad just might be the tool to speed diagnosis, according to researchers from Johns Hopkins School of Medicine.
Report: U.S. outspends 12 countries on healthcare May 8, 2012 -- The U.S. spends more on healthcare than 12 other industrialized countries, yet it does not provide "notably superior" care, according to a new report. The study also sheds some light on the higher utilization of medical imaging in the U.S. relative to other countries.
ASBrS: Radiotherapy after mastectomy may not be beneficial May 7, 2012 -- Women diagnosed with early-stage breast cancer and several involved axillary lymph nodes may not benefit from having radiation therapy following a mastectomy, according to a study presented at the American Society of Breast Surgeons (ASBrS) annual meeting held in Phoenix last week.
Antioxidant formula halves DNA damage from CT May 7, 2012 -- A new study in Radiology has found that ingesting a commercially available combination of antioxidants reduces DNA damage by more than half compared to results obtained without antioxidant protection after irradiation with doses comparable to a CT angiography exam.
Oral antioxidants could prevent DNA damage from radiation May 7, 2012 -- Canadian researchers plan to start clinical trials soon of an oral antioxidant cocktail designed to prevent radiation-induced DNA damage from medical imaging scans. The trial follows tests they've already conduct in humans -- more specifically, themselves.
