A first look at interstitial fluid flow in the brain

05-Jul-2018 - Interstitial fluid transports nutrients and removes waste between the organs and tissues in our body. In the brain, interstitial fluid is thought to be composed of circulating cerebrospinal fluid, cellular waste and blood plasma, and past research has shown a link between interstitial fluid flow ...

Manganese-based MRI contrast agent may be safer alternative to gadolinium-based agents

17-Nov-2017 - A team of Massachusetts General Hospital (MGH) researchers has developed a potential alternative to gadolinium-based contrast agents (GBCAs) for magnetic resonance imaging (MRI). In their report the team describes experiments showing in a primate model that the manganese-based agent Mn-PyC3A ...

Lifelike 3-D cinematic imaging promises numerous medical uses

03-Aug-2017 - Newly developed "cinematic rendering" technology can produce photorealistic 3D images from traditional CT and MRI data, with potential applications in medical education, communication with patients and physicians, and early disease detection. Recently introduced and not currently approved for ...

Seeing more with PET scans

New chemistry for medical imaging

28-Jul-2017 - Researchers have found a surprisingly versatile workaround to create chemical compounds that could prove useful for medical imaging and drug development. The chemical mechanism, discovered by scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC ...

Cell-tracking agents get a boost

31-Jan-2017 - Rice University researchers have synthesized a new and greatly improved generation of contrast agents for tagging and real-time tracking of stem cells in the body. The agent combines ultrashort carbon nanotubes and bismuth clusters that show up on X-rays taken with computed tomography (CT) ...

World's first total-body PET scanner takes a big step forward

19-Jan-2017 - The UC Davis-based EXPLORER consortium, which aims to build a revolutionary total-body PET (positron emission tomography) scanner, has announced the selection of two industry partners to help build the prototype device. They are United Imaging Healthcare America, a North American subsidiary of ...

Novel anti-PSMA imaging agent quickly identifies prostate cancer lesions

05-Dec-2016 - New research demonstrates that a novel imaging agent can quickly and accurately detect metastasis of prostate cancer, even in areas where detection has previously been difficult. The Phase 1 dose-escalation study of Zr-89-desferrioxamine-IAB2M (Zr-89-Df-IAB2M), an anti-PSMA (prostate-specific ...

Scientists create novel imaging technique with potential for medical diagnostics

18-Oct-2016 - A unique new imaging method, called "polarized nuclear imaging" - combining powerful aspects of both magnetic resonance imaging and gamma-ray imaging and developed by two physicists in the University of Virginia's departments of Physics and Radiology has potential for new types of high-resolution ...

Brain modulyzer provides interactive window into the brain

11-Oct-2016 - Did you know that your brain processes information in a hierarchy? As you are reading this page, the signal coming in through your eyes enters your brain through the thalamus, which organizes it. That information then goes on to the primary visual cortex at the back of the brain, where ...

New MRI technique sheds technology's longtime limits

17-Aug-2016 - A new technology harnesses imperfections that typically compromise MRI exams to create images resolved enough to enable consistent diagnoses across populations for the first time. These are findings of a study led by NYU Langone Medical Center. During a scan, antennas hit the atoms making up ...
