Addition of tomosynthesis to standard mammogram increases breast screening accuracy

The addition of three-dimensional breast imaging-a technology called tomosynthesis-to standard digital mammography significantly increases radiologists' diagnostic accuracy while reducing false positive recall rates, according to the results of a multi-center study published in Radiology.

$Digital X-ray radiogrammetry can help identify patients with increased risk of hip fracture$

Digital X-ray radiogrammetry can help identify patients with increased risk of hip fracture

A new study from Karolinska Institutet in Sweden shows, that a technique for measuring bone density called digital X-ray radiogrammetry (or DXR) used on standard hand radiographs can help to identify patients with a higher risk of hip fracture.

Braking mechanism in olfactory neurons helps generate amazing diversity of sensors in the nose

The human nose has millions of olfactory neurons grouped into hundreds of different neuron types. Each of these neuron types expresses only one odorant receptor, and all neurons expressing the same odorant receptor plug into one region in the brain, an organization that allows for specific odors to be sensed.

Study finds several osteoporosis risk factors among post-menopausal women on HRT

A preliminary study of 127 post-menopausal women on hormone replacement therapy in Portugal suggests that there are several risk factors associated with osteoporosis and bone fracture these include age, low bone mineral density, a sedentary lifestyle, coffee consumption and ovariectomy. Details are reported later this month in the International Journal of Medical Engineering and Informatics.

New 3-D digital mammography could improve accuracy of breast cancer screening

A new three-dimensional (3-D) digital mammography technique has the potential to significantly improve the accuracy of breast cancer screening, according to a study published in Radiology.

International Day of Radiology marks 117th anniversary of X-ray discovery

International Day of Radiology — November 8, 2012 — marks the 117th anniversary of the discovery of the X-ray and the tremendous advances in patient care made possible by radiation therapy and medical imaging exams, such as MRI and CT scans. It is also a reminder that Congress needs to pass the Diagnostic Imaging Services Access Protection Act (H.R. 3269/ S. 2347) and halt drastic cuts in Medicare funding for imaging scans. This vital legislation would preserve ready access to lifesaving imaging care and may help reduce harm to seniors already resulting from cutbacks.

Study reveals increased risk of leukemia among Chernobyl cleanup workers

A 20-year study following 110,645 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident in the former Soviet territory of Ukraine shows that the workers share a significant increased risk of developing leukemia. The results may help scientists better define cancer risk associated with low doses of radiation from medical diagnostic radiation procedures such as computed tomography scans and other sources.

Researchers figure out 3D shape of promising TB drug target

Researchers at Johns Hopkins have figured out the three-dimensional shape of the protein responsible for creating unique bonds within the cell wall of the bacteria that cause tuberculosis. The bonds make the bacteria resistant to currently available drug therapies, contributing to the alarming rise of these super-bacteria throughout the world.

Simple educational intervention could improve treatment rates for osteoporosis

Older patients who visited local ERs for chest pain or breathing problems and had chest x-rays reveal unknown spinal fractures, were more apt to receive osteoporosis treatment afterward if a simple intervention was used, recently published medical research from the University of Alberta has found.

Scientists develop new breast cancer screening method with less radiation

Scientists have developed a way to produce three-dimensional X-ray images of the breast at a radiation dose that is lower than the 2D radiography methods used in clinics today. The new method enables the production of 3D diagnostic computed tomography (CT) images with a spatial resolution 2-3 times higher than present hospital scanners, but with a radiation dose that is about 25 times lower.
