Early CT ‘definitive’ for subarachnoid hemorrhage diagnosis

Cerebrospinal fluid analysis is only necessary for patients with thunderclap headache and a negative computed tomography scan if they undergo imaging more than 6 hours after headache onset, research suggests.

Toshiba’s Vantage Titan 1.5T and 3T MR systems can help visualize CSF bulk flow

Cerebral Spinal Fluid (CSF), the clear water-like fluid that surrounds the brain and the spinal cord, plays a key role in maintaining balanced brain dynamics. For the first time, CSF bulk flow can now be visualized non-invasively with Toshiba America Medical Systems, Inc.'s Vantage Titan 1.5T and 3T MR systems.

Insight into neural basis of human consciousness

Which areas of the brain help us to perceive our world in a self-reflective manner is difficult to measure. During wakefulness, we are always conscious of ourselves. In sleep, however, we are not. But there are people, known as lucid dreamers, who can become aware of dreaming during sleep. Studies employing magnetic resonance tomography (MRT) have now been able to demonstrate that a specific cortical network consisting of the right dorsolateral prefrontal cortex, the frontopolar regions and the precuneus is activated when this lucid consciousness is attained.

Research roundup: Slowdown in medical imaging; Hospitals' efforts mixed on reducing readmissions

Recent research showed a slowdown in the use of medical imaging for people enrolled in Medicare. This article follows up and finds that annual imaging growth slowed down from an average of 14 percent between 2000 and 2005 to 2.6 percent between 2006 and 2009. An analysis of commercial insurance claims shows a similar trend outside of Medicare. Based on

MEG-MRI combined device for mapping the human brain

Researchers at Aalto University in Finland have developed the world's first device designed for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain. The merging of these two technologies will produce unprecedented accuracy in locating brain electrical activity non-invasively.

Novel method of identifying molecules that can help prevent diabetes

Pancreatic beta cells produce insulin, responsible for controlling blood sugar levels and thus essential for our survival. Among the numerous factors that affect the workings of these cells, a protein called Cx36 was identified a few months ago by a research team at the UNIGE.

New tool uses fluorescence to distinguish cancerous tissue from normal one in low-grade tumors

A new probe developed collaboratively at Norris Cotton Cancer Center and Dartmouth College's Thayer School of Engineering uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.
