A computer-aided detection (CAD) system is helping radiologists to more quickly and accurately determine the sizes and locations of cancers found on breast MRI—information that could change patients’ treatment, a new study shows.
The study, undertaken at Clinica Girona in Girona, Spain, compared the CAD system to breast imaging software that comes standard with MRI machines, said Joan C. Vilanova, MD, director of the department of magnetic resonance and lead author of the study. Thirty-six patients with known breast cancer underwent an MRI examination using the standard software and the CAD system.
The CAD system in conjunction with the MRI examination allowed the radiologist to more accurately determine the size of the cancer lesions, Dr. Vilanova said; the size correlated more closely to what was seen under the microscope, he added. “The quality of the final (postprocessed) CAD system images was better than the standard software images in 83% of the cases,” said Dr. Vilanova. In addition, it took radiologists an average 12 minutes to analyze and interpret the CAD system images compared to 19 minutes for the standard MRI software images. A breast MRI study generates more than 1,000 images per examination, according to Dr. Vilanova.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
