A modified technique that uses the eyes as the line of reference means a 50 percent reduction in the time necessary to take MRI images of the fetal brain.
"One of the challenges of imaging the fetal head is that the fetus can move during the study, so it is often difficult to obtain the three different imaging views that best show intracranial anatomy especially when study time is prolonged." said Keyanoosh Hosseinzadeh, MD, Chief of Body MRI at the University of Pittsburgh Medical Center, and lead author of the study. "When we draw a line of reference through the eyes, and subsequent imaging is performed along that plane, we can then rapidly acquire the three imaging planes," he said.
The total examination time, using the modified technique is now about 12 minutes, Dr Hosseinzadeh said. That compares to the standard technique that can take at least twice that long, he added.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
