Combining 3 techniques to boost brain-imaging precision

Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping. The new "trimodal" approach combines…

Researchers develop powerful pocket-sized imaging device

Before Wilhelm Röntgen, a mechanical engineer, discovered a new type of electromagnetic radiation in 1895, physicians could only dream of being able to see inside the body. Within a year of Röntgen’s discovery, X-rays were being used to identify tumors. Within 10 years, hospitals were using X-rays to help diagnose and treat patients. In 1972, computed tomography (CT) scans were developed. In…

Can drinking cocoa make you smarter?

Increased consumption of flavanols – a group of molecules which occur naturally in fruit and vegetables – can increase your mental agility, according to new research. A team at the University of Birmingham has found that people given a cocoa drink containing high levels of flavanols were able to complete certain cognitive tasks more efficiently than when drinking a non-flavanol enriched-drink.

VeinViewer® - Innovation in visualization

The VeinViewer® uses harmless near-infrared (NIR) light which is directed towards the patient’s skin. Haemoglobin in the blood absorbs the NIR and the surrounding tissue reflects it back to the VeinViewer® device, where the data is processed into an image, colour is added and the image sent back to the skin to provide a real time visualization of the blood vessels and patterns up to 10mm…

New imaging method to detect and monitor liver disease

It’s currently difficult to screen for certain liver diseases and to monitor these conditions once they’re discovered. A team led by investigators at Massachusetts General Hospital (MGH) and the Massachusetts Institute of Technology (MIT) recently developed a non-invasive imaging method that has promising clinical potential to accomplish both goals. The technique is described in a study…

Macular degeneration: Gene therapy restores vision

Macular degeneration is one of the major reasons for visual impairment, round the globe, close to 200 million people are affected. It damages the photoreceptors in the retina, which lose their sensitivity to light. This can lead to impaired vision or even complete blindness. Scientists at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) together with colleagues from the German…

Robot uses AI and imaging to draw blood

Engineers at Rutgers University have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their most recent research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on…

Nano-patch stores medical information under the skin

Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there’s often no easy way to determine who needs a particular vaccine. Researchers at the Massachusetts Institute of Technology (MIT)…

Intracoronary imaging advances

Interventional cardiologists have been aware of the value of intracoronary (IC) imaging in clinical practice for more than twenty years. However, recent developments and improvements in modalities and software have enabled huge strides in its range and scope for both diagnostic assessment and in percutaneous coronary interventions. Imaging options now include intravascular ultrasound (IVUS),…

Microbots show promise in tumor treatment

Targeting medical treatment to an ailing body part is a practice as old as medicine itself. A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside the body and is not so easy to reach. In such cases, a treatment like surgery or chemotherapy might be called for. A pair of researchers in Caltech's Division of Engineering and…

Male birth control: as easy as a layered cocktail?

For decades, women have shouldered most of the burden of contraception. However, long-term use of female birth control pills could increase the risk for side effects such as blood clots or breast cancer. Now, inspired by colorful layered cocktails, researchers have developed a medium-term, reversible male contraceptive. They report their results in the journal ACS Nano. Common forms of male…

Checking a lump for malignancy, finding out if food is fresh, just with your smartphone? It’s possible, according to Eindhoven University of Technology researchers in the Netherlands. Their recently presented spectrometer is small enough to insert into a smartphone. This device is not yet ready for use on a big scale, Professor Andrea Fiore, supervisor of the Eindhoven research team points out.…

Breast cancer: Near-infrared light shows chemo beneficiaries

A new optical imaging system developed at Columbia University uses red and near-infrared light to identify breast cancer patients who will respond to chemotherapy. The imaging system may be able to predict response to chemotherapy as early as two weeks after beginning treatment. Findings from a first pilot study of the new imaging system—a noninvasive method of measuring blood flow dynamics in…

Nanosensors uncloak the mysteries of brain chemistry

Nanosensors are incredible information-gathering tools for myriad applications, including molecular targets such as the brain. Neurotransmitter molecules govern brain function through chemistry found deep within the brain, so University of California, Berkeley researchers are developing nanosensors to gain a better understanding of exactly how this all plays out. During the AVS 64th…

Infra-red light to deteact early signs of oesophageal cancer

Researchers at the Cancer Research UK Cambridge Institute sprayed a dye on oesophageal tissue samples taken from people with Barrett’s oesophagus – a condition that increases the risk of developing oesophageal cancer. The dye sticks to healthy oesophageal cells but not to pre-cancerous cells. They then shone near-infrared light - which is just beyond the red colours that our eyes can normally…

A pill could improve breast cancer diagnoses

The ongoing debate about breast cancer diagnostics has left many women confused — particularly over what age they should get mammograms and who needs treatment. An issue with current methods is that they often identify lumps but cannot conclusively pinpoint which ones are cancerous. To help resolve this uncertainty, researchers have developed a pill that could improve imaging techniques so that…

First OCT tissue images

A UK collaboration, led by an optical imaging company has produced its first optical coherence tomography (OCT) tissue images at a wavelength of 1 µm. Based on interferometry, OCT works by analysing near-infrared light reflected from a sample and using differences in the reflected intensities to create high-resolution images. Employing 1 µm light - as opposed to the longer wavelength…

A new imaging tool?

Mammography is the common way to detect breast cancer. But it's not perfect: it struggles to image dense glandular tissue or early-stage tumours. Magnetic resonance imaging (MRI) offers best sensivity but it is expensiv and not always specific enough. Now researchers have come up with another option: a scanner that integrates thermoacoustic and photoacoustic tomography to achieve dual-contrast…

Nanorods of gold blast holes in cancer tumours

USA — Miniscule gold 'nanorods' triggered by a laser beam can blast holes in tumour cell membranes, which then activates a complex biochemical mechanism that leads to the tumour cell to self-destruct, according to researchers at the Weldon School of Biomedical Engineering in Purdue University, Idaho.
