Researchers propose hybrid approach for tracking laparoscopic ultrasound transducers Laparoscopic surgery, a less invasive alternative to conventional open surgery, involves inserting thin tubes with a tiny camera and surgical instruments into the abdomen. To visualize specific surgical targets, ultrasound imaging is used in conjunction with the surgery. However, ultrasound images are viewed on a separate screen, requiring the surgeon to mentally combine the camera and ultrasound data. Modern ...

Imaging technique can differentiate Alzheimers disease from dementia with Lewy bodies Scientists in Portugal and the United Kingdom were able to confirm that an imaging technique that traces neuronal dopaminergic deficiency in the brain is able to differentiate, in vivo, dementia with Lewy This could have important implications for the specific management and treatment of these conditions. American actor Robin Williams had a neurodegenerative brain disease called dementia with Lewy bodies (DLB...

Targeted pulses of ultrasound can help treat a range of brain diseases Ultrasound is not only used as an imaging technique but targeted pulses of ultrasound can be used as a highly accurate treatment for a range of brain diseases, for which there were previously only limited treatment options. Over the last few years, several revolutionary techniques of this kind have been developed, primarily in Toronto but also at MedUni Vienna. The Viennese technique improves brain functions by externally a...

AI technology can help prevent adverse effect of immunotherapy in certain lung cancer patients Researchers at Case Western Reserve University, using artificial intelligence (AI) to analyze simple tissue scans, say they have discovered biomarkers that could tell doctors which lung cancer patients might actually get worse from immunotherapy. Until recently, researchers and oncologists had placed these lung cancer patients into two broad categories: those who would benefit from immunotherapy, and ...

Research shows how air pollution has a detrimental impact on cardiovascular health Tiny particles of air pollution -- called fine particulate matter -- can have a range of effects on health, and exposure to high levels is a known risk factor for cardiovascular disease. New research led by investigators at Massachusetts General Hospital (MGH) reveals that fine particulate matter has a detrimental impact on cardiovascular health by activating the production of inflammatory cells in the bone marro...

NeuroVision Imaging receives ADDF funding to develop biomarker tests for Alzheimers disease NeuroVision Imaging Inc., announced today it has received an investment from the Alzheimers Drug Discovery Foundation (ADDF) to support developing reliable, affordable biomarker tests for Alzheimers disease and other forms of dementia and neurodegenerative disorders. Many of the existing diagnostics tests for Alzheimers are expensive and invasive, but the ability to detect and measure biomarkers in a blo...

Reducing barriers in cancer care for LGBTQ2SPIA+ patients In an upcoming issue of the Journal of Medical Imaging and Radiation Sciences, published by Elsevier, undergraduate researchers from the University of Albertas Radiation Therapy Program in the Faculty of Medicine and Dentistry describe how LGBTQ2SPIA+ patients face unique cancer risks, including fear of discrimination, higher incidence of certain cancer sites, and lower screening rates, resulting in more cancers detected at later stages...

Automated method identifies and tracks harmful tau deposits involved in Alzheimers disease Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimers disease, and detecting their buildup at an early stage may allow clinicians to intervene before the condition has a chance to take hold. A team led by investigators at Massachusetts General Hospital (MGH) has now developed an automated method that can identify and track the deve...

CoCID project aims to develop soft X-ray microscope for visualizing cellular origin of diseases CoCID (Compact Cell Imaging Device), a €5.7 million, four-year, pan-European research and innovation project, funded through Horizon 2020, has officially commenced. CoCID is focused on the development of a soft X-ray-based methodology that enables fast and inexpensive three-dimensional imaging of whole internal structure of intact biological cells. The objective of CoCID is to develop a lab-scale, ...

Novel deep learning system can predict cardiovascular risk from CT scans Coronary artery calcification -- the buildup of calcified plaque in the walls of the hearts arteries -- is an important predictor of adverse cardiovascular events like heart attacks. Coronary calcium can be detected by computed tomography (CT) scans, but quantifying the amount of plaque requires radiological expertise, time and specialized equipment. In practice, even though chest CT scans are fairly common, calcium score ...
