Sniffing out a better chemical sensor
Marrying a sensitive detector technology capable of distinguishing hundreds of different chemical compounds with a pattern-recognition module that mimics the way animals recognize odors, researchers at the National Institute of Standards and Technology (NIST) have created a new approach for "electronic noses." view more (2008-10-30)
Touching outlawed by hands-free monitor - Photon02
A Loughborough University research team, led by Professor Peter Smith and Vincent Crabtree, has developed a way of monitoring the blood flowing in human body tissue without actually touching the skin. This hands-free technique could one day be used to assess patients during surgery and monitor the healing of wounds or burns. Other applications... view more... (2002-08-30)
New Non-Invasive Method In Lung Diagnostics
Magnetic resonance imaging (MRI) as a non-invasive diagnostic method has been evolving into an attractive alternative to methods which are associated with radiation exposure. This development now also starts to manifest itself in lung perfusion imaging. This was reported by Dr. Christian Fink and colleagues of the Radiology Division of the... view more... (2004-06-24)
Pocket-sized magnetic resonance imaging
The term "MRI scan" brings to mind the gigantic, expensive machines that are installed in hospitals. But research scientists have now developed small portable MRI scanners that perform their services in the field: for instance to examine ice cores. view more (2008-07-09)
New molecular imaging techniques may lead to advances in disease treatment
A promising new technique has been developed that will enable more accurate non-invasive positron emission tomography (PET) imaging of new cells injected into the body, according to researchers at SNM's 55th Annual Meeting. view more (2008-06-17)
Study tracks increasing use of CT on pregnant women
Researchers have found that over a 10-year period radiologic exams on pregnant women have more than doubled, according to a study published in the online edition of Radiology. view more (2009-03-17)
Yerkes researchers identify language feature unique to human brain
Researchers at the Yerkes National Primate Research Center, Emory University, have identified a language feature unique to the human brain that is shedding light on how human language evolved. The study marks the first use of diffusion tensor imaging (DTI), a non-invasive imaging technique, to compare human brain structures to those of... view more... (2008-03-24)
Synergy between biology and physics drives cell-imaging technology
Developing techniques to image the complex biological systems found at the sub-cellular level has traditionally been hampered by divisions between the academic fields of biology and physics. However, a new interdisciplinary zeal has seen a number of exciting advances in super-resolution imaging technologies. view more (2008-06-02)
Gold beads show previously unseen parts of the eye
A new study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO), shows that gold beads injected into eye tissue can be used to obtain images of important structures in the orbit that cannot be seen with Magnetic Resonance Imaging (MRI) or other imaging... view more...

Risk and reward compete in brain
That familiar pull between the promise of victory and the dread of defeat - whether in money, love or sport - is rooted in the brain's architecture, according to a new imaging study. view more (2008-10-10)
World's most powerful MRI ready to scan human brain
The world's most powerful medical magnetic resonance imaging machine, the 9.4 Tesla at the University of Illinois at Chicago, has successfully completed safety trials and may soon offer physicians a real-time view of biological processes in the human brain. view more (2007-12-05)
Sandia researchers construct carbon nanotube device that can detect colors of the rainbow
Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, study how those molecules respond to light, observe how the molecules change shapes, and understand other fundamental... view more...

Arsenic aids tumor imaging when joined to cancer-homing drug, UT Southwestern researchers find
Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found. view more (2008-03-03)
Elasticity imaging identifies cancers and reduces breast biopsies
A new ultrasound technique allows radiologists to accurately distinguish benign from malignant breast lesions. Using elasticity imaging, researchers correctly identified both cancerous and harmless lesions in nearly all of the cases studied. view more (2006-11-28)
High-temperature superconductors: magnetic glue may be the clue
Striking pictures of magnetic waves inside advanced ceramics may be the clue to understanding how they can transmit electricity without losing energy, according to results obtained by two teams of scientists using the UK's world-leading ISIS neutron source in Oxfordshire and published this week in the journal Nature. The ceramics, known as... view more... (2004-06-02)
New technology sharpens X-ray vision
Researchers at the Paul Scherrer Institute (PSI) and the EPFL in Switzerland have developed a novel method for producing dark-field x-ray images at wavelengths used in typical medical and industrial imaging equipment. view more (2008-01-21)
PET/CT Imaging Proves Golden for Detecting Cancer in Children
PET/CT imaging exhibits significantly higher sensitivity, specificity and accuracy than conventional imaging when it comes to detecting malignant tumors in children. view more (2007-12-13)
MINOS experiment sheds light on mystery of neutrino disappearance
An international collaboration of scientists at the Department of Energy's Fermi National Accelerator Laboratory announced the first results of a new neutrino experiment. view more (2006-03-31)
NIST posts online database of cryogenic materials properties
In response to numerous inquiries from academia, industry, and other government labs, the National Institute of Standards and Technology (NIST) recently published a new database on the properties of solid materials at temperatures ranging from cryogenic (as low as 4 K, which is -269 degrees C or -452 degrees F) to room temperature. view more (2007-11-09)
Molecular imaging holds promise for early intervention in common uterine cancer
A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma"-one of the most common malignant female tumors. view more (2009-10-01)
