International conference showcases breadth of research possible with zebrafish

It's clear where the black-and-white striped zebrafish got its name, but less obvious at first glance is what zebrafish has to do with biomedical research. Amazingly, it has biological similarities to humans, which are making this small freshwater fish an increasingly popular model organism for studying vertebrate development, genetics, physiology, and mechanisms of disease.

Use, overuse of imaging tests adds about $100 billion to U.S. medical bills

The use of diagnostic imaging has nearly tripled since the mid-1990s, according to a new study, raising questions about whether the benefits outweigh the risks of increased radiation exposure.

Significant increase in use of CT, MRI and PET imaging over the last two decades

Among six large integrated health care systems between 1996 and 2010 there was a substantial increase in the use of advanced diagnostic imaging, including approximately a tripling of the use of computed tomography and nearly a quadrupling of the use of magnetic resonance imaging, as well as a substantial increase in estimated radiation exposure, according to a study in the June 13 issue of JAMA.

Study shows increase in medical imaging in health maintenance organization systems

Concern about overexposure to radiation due to excessive use of medical imaging has come to the fore in recent years. Now, a study led by researchers at the University of California, San Francisco (UCSF) and Group Health Research Institute, shows that medical imaging is increasing even in health maintenance organization systems (HMOs), which don't have a financial incentive to conduct them.

Unnecessary medical imaging can reduce risk of breast cancer in women

A report issued by the Institute of Medicine (IOM) last December reviewed all the available scientific data compiled to date about potential environmental risks of breast cancer-factors such as pesticides, beauty products, household chemicals, and the plastics used to make water bottles.

Appropriate CT scans may save and extend lives of children

The American College of Radiology (ACR) urges that results of a study (Pearce et al) to be published in the Lancet regarding radiation risk from pediatric computed tomography (CT) scans should not keep parents from getting needed medical imaging care for their children, but should be discussed with their physician and factored into their shared decision making before an imaging scan is performed.

Risk of leukaemia and brain cancer in children could be tripled by radiation exposure from CT scans

Radiation exposure received from 2 to 3 computed tomography (CT) scans of the head in childhood (aged under 15 years)—giving a cumulative dose of around 60 mGy— can triple the risk of later developing brain cancer, while around 5 to 10 such scans (cumulative dose around 50 mGy) could triple the risk of developing leukaemia (with the differing number of scans related to different absorption rates of the brain versus the bone marrow and age at time of scanning).

Femoropopliteal total occlusion therapy advances

Researchers report that a novel balloon catheter system, the ENABLER-P, may provide an effective method of recanalizing chronic total occlusions of the superficial femoral artery and popliteal arteries.

Survivors of childhood cancers are at increased risk for GI cancers

Survivors of childhood cancers are at an increased risk of another battle with cancer later in life, according to new research published online June 4 by the Annals of Internal Medicine. In the largest study to date of risk for gastrointestinal (GI) cancers among people first diagnosed with cancer before the age of 21, researchers found that childhood cancer survivors develop these malignancies at a rate nearly five times that of the general population.

Cardinal Health to produce new AD diagnostic imaging agent, Amyvid

Cardinal Health today announced that it will manufacture and distribute Amyvid, Eli Lilly and Company's new diagnostic imaging agent that aids in the evaluation of adult patients with cognitive impairment who are being evaluated for Alzheimer's Disease and other causes of cognitive decline. The commercial launch of Amyvid is scheduled for June 1, 2012.
