First MR images to show complete borders in human cerebral cortex

Understanding functional properties of the brain’s structural units is one of the main aims of brain research. Until now only fragmentary borders of brain areas could be identified in vivo since the resolution in MR images was not high enough.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Contrast agent for tumor diagnostics

X-rays are not the only way: visible and especially infrared light can also be used to image human tissue. The effectiveness of optical imaging processes can be significantly improved with suitable dyes used as contrast agents. In the journal Angewandte Chemie, a team led by Wenbin Lin at the University of North Carolina (Chapel Hill, USA) has now introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal–organic coordination polymer, which allows an extraordinarily high level of dye loading.

Now get a 3-D kidney printout to replace damaged kidneys: A regeneration science innovation

In what seems like science fiction, Dr. Anthony Atala, a regenerative medicine specialist at Wake Forest University, is pioneering the use of printing techniques to reconstruct and repair human flesh and organs. His basis is a combination of cultured human cells and scaffolding built or woven from organic material.

dicomPACS®DX-R 2.0 sets new standards in image processing

OR Technology will present a new version of its X-ray acquisition software at this year’s ECR (European Congress of Radiology) in Vienna. dicomPACS®DX-R version 2.0 provides extended image processing – Cognition Optimised Processing. New adjustment options such as automatic pixel correction reduce image interference and improve the overall impression of the image. Optimal contrast regulation covering the entire image ensures improved recognition of details in soft tissue and bones.

Malaria parasite caught in action on film for the first time

Australian researchers have managed to take pictures of microscopic malaria parasite as it invades a human red blood cell. This will provide a deeper understanding of the parasite’s behaviour and may help fight it. Up to 10% of the world’s population contract malaria every year and a million people, mostly pregnant women and children, die as a result of the parasite transmitted by infected mosquitoes.

Radiation hazard from diagnostic tests

In a nationwide safety effort launched this week in Chicago health care providers are pledging to stop the overuse of radiation on patients during medical examinations. The pledge at the Image Wisely campaign is signed so far by nearly 700 health care providers. It pledges to use the least radiation necessary on patients for a procedure. An expert panel at a radiology meeting Thursday said the campaign may lead to more review of protocols, more accreditation of imaging facilities and more widely shared standards on proper radiation doses.

Simple test and an MRI predicts future Alzheimer’s disease

Until now is has been believed that Alzheimer’s disease and other forms of dementia could be diagnosed only when symptoms appear which almost always means when patients are in their 70s or 80s. Now the latest research shows that some brain lesions are characteristic of Alzheimer’s disease and can be detected in the brains of healthy people in their 40s. Along with this a simple mental skills test may be able to detect the problem many years sooner than previously thought.

Jelly fish glow may help detect early stage cancer

Researcher Professor Norman Maitland of the Yorkshire Cancer Research Laboratory at York University, feels that this technology could be at least ten times better than CT scanners at detecting tumors. He explained, “Cancers deep within the body are difficult to spot at an early stage and early diagnosis is critical for the successful treatment of any form of cancer.

Noninvasive monitoring of cardiac allograft vasculopathy with fast MR imaging

Cardiac allograft vasculopathy (CAV), also known as chronicle rejection, is a leading cause of graft (foreign heart) loss and death in patients who survive the first year after heart transplantation. The typical pathological change of CAV is gradually thickening of coronary wall in "foreign" heart due to continuous immunological reaction between donated heart and the host. In some cases, undetected CAV may silently cause graft failure with global myocardial ischemia without any documented infarction signs. Thus, continually monitoring development of asymptomatic CAV is important for selecting prophylactic strategies to get better prognosis. However, most current examinations of detecting CAV are invasive and with certain risks.
