Method Makes PET Tracers out of Common Biomolecules

Researchers from the University of North Carolina Lineberger Comprehensive Cancer Center have developed new radioactive tracers to track pharmaceuticals in the body and to image cancer. The findings, reported in journal Science, describe the new chemistry they have developed, along with data that demonstrate that the team was able to radioactively (Read more...)

Ultra-Thin Probe Assesses Tissues Deep Within Lungs

Assessing the health of tissues deep inside the body is a major need and challenge in medicine. Imaging modalities such as MRI, CT, and ultrasound provide very little information about the composition and environment of tissues being examined. Now, researchers at the University of Edinburgh, Heriot-Watt University, and Bath University, all in the U (Read more...)

New AI Tool, HeadXNet, to Help Detect Brain Aneurysms

Researchers from Stanford University have developed a new AI tool, dubbed HeadXNet that detects brain aneurysms from computed tomographic angiography (CTA) scans. Their work, recently published in JAMA Network Open, demonstrates that their AI tool helped radiologists identify 6 more scans with aneurysm for every 100 scans already diagnosed with ane (Read more...)

Study of People with Extra Fingers Points to New Approaches for Development of Prosthetic Devices

Kids with extra fingers on their hands usually have them removed soon after birth, but some get to keep them into adulthood. This condition, known as polydactyly, is usually looked upon as a disability that has to be studied and addressed. Researchers at the University of Freiburg in Germany, Imperial College London, and the Université [&hel (Read more...)

Patches Made of Heart Tissue Going to Clinical Trials

Stem cell therapies to heal damaged hearts have proven to be lacking so far, probably because simply injecting new cells into afflicted regions isn’t enough. Researchers from Imperial College London have now created patches made of cardiac tissue to sew over damaged areas of the heart. These patches, which can beat on their own to […]

ControlRad Trace Add-On for C-arms Reduces Radiation Exposure

ControlRad, a company based outside of Atlanta, Georgia, won FDA clearance for its ControlRad Trace radiation reduction solution. Designed for integration with C-arms, the product can help reduce X-ray radiation exposure to patients and nearby clinicians in most fluoroscopic procedures. The system works thanks to titanium filters that move in front (Read more...)

Philips Unveils IntraSight Multi-Modality Imaging Platform

For years, catheter-based minimally invasive procedures have depended on X-ray imaging to guide physicians toward the treatment site. New tools, including intravascular ultrasound (IVUS) and fractional flow reserve (FFR), which measures blood pressure inside a vessel, are giving physicians additional perspectives. Using these modalities in a single (Read more...)

Impella CP with SmartAssist: A Newly FDA Approved Heart Pump with Optical Positioning Sensor

Abiomed, the maker of popular left ventricular assist devices, is releasing its newly FDA approved Impella CP with SmartAssist device. The pump features an optical sensor that physicians can use to position and reposition the device without relying on a cath lab, X-ray, or ultrasound imaging. The sensor can be used either during initial implantatio (Read more...)

FDA Clears Software to Spot Collapsed Lung in Chest X-rays

Zebra Medical Vision, an Israeli firm, landed FDA clearance for the HealthPNX automated chest X-ray analysis software that can independently spot signs of pneumothorax (PNX), colloquially known as collapsed lung. The software can help radiologists quickly and confidently identify the cause of a patient’s symptoms, allowing for emergency treat (Read more...)

FDA Approves More Accurate GORE TAG Conformable Thoracic Stent Graft with ACTIVE CONTROL System

Gore just announced winning FDA approval for its GORE TAG Conformable Thoracic Stent Graft with ACTIVE CONTROL System. The thoracic endovascular aortic repair system is based on the Conformable GORE TAG Device, but with a new, more robust control mechanism that helps to position the implant with greater accuracy and confidence. The implant its (Read more...)
