Blood Test Detects Multiple Types of Cancer

  • Magazine Article
  • TBMG-36176
Published 2020-03-01 by Tech Briefs Media Group in United States

A new blood test uses next-generation sequencing technology to probe DNA for tiny chemical tags (methylation) that influence whether genes are active or inactive. When applied to nearly 3,600 blood samples — some from patients with cancer and some from people who had not been diagnosed with cancer at the time of the blood draw — the test successfully picked up a cancer signal from the cancer patient samples and correctly identified the tissue from where the cancer began (the tissue of origin). The test’s specificity — its ability to return a positive result only when cancer is actually present — was high, as was its ability to pinpoint the organ or tissue of origin.

AI Identifies Previously Unknown Cancer Features

  • Magazine Article
  • TBMG-36023
Published 2020-02-01 by Tech Briefs Media Group in United States

Artificial intelligence (AI) technology has successfully found features in pathology images from human cancer patients, without annotation, that could be understood by human doctors. Further, the AI identified features relevant to cancer prognosis that were not previously noted by pathologists, leading to a higher accuracy of prostate cancer recurrence compared to pathologist-based diagnosis. Combining the predictions made by the AI with predictions by human pathologists led to an even greater accuracy.

Diagnosing Prostate Cancer with Artificial Intelligence

  • Magazine Article
  • TBMG-36021
Published 2020-02-01 by Tech Briefs Media Group in United States

Researchers at Radboud UMC have developed a “deep learning” system that is better than most pathologists at determining the aggressiveness of prostate cancer. The AI system, which uses tissue samples to arrive at its diagnosis, taught itself to identify prostate cancer based on data from over 1200 patients. The Radboud team is now working with researchers from the Karolinska Institute in Sweden and Kaggle, a Google subsidiary, with the intention to continue developing these methods as part of a major international competition.

Smart Photonic Contact Lens for Diabetic Diagnosis and Retinopathy Treatment

  • TBMG-36022
Published 2020-02-01 by Tech Briefs Media Group in United States

Diabetic patients need to measure their blood sugar level by drawing blood before and after a meal. It is easy to develop complications due to diabetes. Recently, a research team from Pohang University of Science and Technology (POSTECH) developed technology that allows diagnosis of diabetes and treatment of diabetic retinopathy just by wearing smart light-emitting diode (LED) contact lens. With this technology, it the researchers hope to develop wearable diagnostic and therapeutic devices for diabetes.

AI Blood Test Spot Signs of Brain Tumors

  • Magazine Article
  • TBMG-35768
Published 2020-01-01 by Tech Briefs Media Group in United States

Researchers have developed a test that works by detecting chemical clues shed by brain tumors into the blood. They say it could help improve brain tumor survival by making diagnosis quicker and more efficient.

Low-Field MRI Improves Lung, Cardiac Imaging

  • Magazine Article
  • TBMG-35773
Published 2020-01-01 by Tech Briefs Media Group in United States

National Institutes of Health researchers, along with researchers at Siemens, have developed a high-performance, low-magnetic-field MRI system that vastly improves image quality of the lungs and other internal structures of the human body. The new system is more compatible with interventional devices that could greatly enhance image-guided procedures that diagnose and treat disease, and the system makes medical imaging more affordable and accessible for patients.
