Optical Coherence Tomography (OCT) has been demonstrated to be able to differentiate between benign and potentially malignant pancreatic cysts. Researchers from Massachusetts General Hospital, Physical Sciences, Inc., Brigham and Women’s Hospital, and Brandeis University have published their findings in Biomedical Optics Express. In their study they used surgically removed pancreas specimens of patients with pancreatic cysts to assess them with OCT and compare the results with histology examinations. OCT was able to reveal specific morphological characteristics used to differentiate between the low-risk and high-risk cysts. Read more »

A technique to identify myelination in order to map the layout of cortical areas in the human brain has been developed by researchers led by David van Essen at the Washington University School of Medicine in St. Louis. It is generally known that myelination levels are different throughout the cerebral cortex. The best way to assess it is to investigate the brain post mortem. Using the new technique of myelination mapping, it will be possible to accurately map individual cortical areas in vivo. The researchers used their method on a group of control subjects and found an excellent agreement between the spatial gradients of the myelin maps and already published anatomical and functional information about cortical areas, mostly based on post-mortem histology.
Using data from T1 and T2-weighted MRIs, the team has been able to Read more »

GE Healthcare has received the FDA OK for its Optima CT660 computed tomography (CT) system. The CT660, which is already available in Europe, Latin America and Asia, distinguishes itself by its compact footprint combined with a modular design and low dose imaging. In addition, it is also one of the most energy efficient CT scanners available and has an “environmental design” that eases refurbishment and end-of-life recycling. The scanner itself is scalable from 32 to 128 slices through purchasable options and features automatic table positioning and a color 12-inch integrated gantry display monitor. Read more »

It seems intuitive (at least to Medgadgeteers) that mobile technology can be used to improve health outcomes, but we still need studies to actually put data behind this idea. A recent study of the DiabetesManager mobile health platform from WellDoc is a step in this direction. We last reported about WellDoc’s mobile diabetes application in 2010, and since that time it has been tested in a clinical trial and was shown to reduce HgbA1c by 1.9%.
The DiabetesManager is a behavioral coaching and clinical decision support system. Patients enter details about blood glucose values, medications, and behaviors via mobile phone, and health care providers receive quarterly summaries based on this information. Read more »

Researchers from Columbia University have developed a “lab on a chip” HIV and syphilis test, and are now reporting the first results from tests in the field conducted in Rwanda. The mChip, as it is called, is the size of a credit card and replicates all steps of an ELISA test, at a lower total material cost and within 20 minutes. After application of a blood sample, the chip is inserted into a $100 battery-powered handheld analyzer. It needs only 1 μl of unprocessed whole blood and does not require any user interpretation of the signal, providing a clear-cut yes or no result.
Right now, HIV testing in developing countries either relies on expensive laboratory testing taking a long time, or uses cheaper methods based on lateral flow, which, although very rapid, do not provide very reliable results. The mChip combines Read more »
