AI Detects and Measures Small Vessel Disease in Brain CT Scans
Clinicial researchers at Imperial College London and the University of Edinburgh have developed an artificial intelligence software for identifying and quantifying small vessel disease, a frequent cause of dementia and stroke in older people, from CT scans. The investigators have already tested the software at Imperial’s Charing Cross Hospita (Read more...)
CurveBeam’s Tiny InReach CT Scanner Cleared by FDA
CurveBeam‘s InReach point-of-care extremity CT system garnered FDA clearance for use in scanning the arms, hands, wrists, and elbows, as well as the feet and legs. This is one of the smallest CT scanners out there, giving a detailed 3D view of the extremities that digital X-rays can’t provide. The device doesn’t need any additiona (Read more...)

AcQMap Now Imaging Hearts with Ultrasound and Electricity in U.S.
Acutus Medical of Carlsbad, California, having won FDA clearance for its AcQMap last fall, has announced that the system has been used for the first time in the United States. The system’s novel catheter uses ultrasound and electrical tissue conduction mapping to provide a novel electrophysiologic live view inside the heart. Both th (Read more...)
Wearable MRI Detector Allows Imaging of Moving Joints
Researchers at NYU Langone Health have developed a wearable detector glove that allows them to image a moving hand in an MRI scanner. The glove allows for high-quality images of moving joints, whereby tendons and ligaments can be seen moving in relation to bones and muscle, and could be useful in helping to guide surgery. […]
MRI Maps of Brain’s Visual Cortex Connectivity Point to Mental Illness
Researchers at Duke University may have identified a way of predicting future (!) onset of mental illness. They used magnetic resonance imaging (MRI) to study how various parts of the brain communicate with each other. What the investigators noticed is that those individuals with a poorly functioning visual cortex, that doesn’t seem to talk w (Read more...)
Imaging Agent to Spot Signs of Rheumatoid Arthritis
A research team based in South Korea has developed a positron-emission tomography (PET) tracer that may help to diagnose rheumatoid arthritis (RA). The tracer spots the translocator protein (TSPO), which is produced when white blood cells are active as in the joints of RA patients. Study in Journal of Nuclear Medicine: 18F-FEDAC as a Targeting (Read more...)
Genetesis: A Teenage Cincinnati Area MedTech Success Story
During a recent tour of some of the Cincinnati area life science companies, we had a chance to visit Genetesis, a firm in nearby Mason that has developed a novel scanner to help diagnose the source of chest pain. Aside from the innovative technology behind the equipment, what’s notable about this startup is that founder […]
Agfa’s DR 800 Multi-Purpose Imaging System Gets Green Light from FDA
Agfa landed FDA clearance for its DR 800 digital imaging system that can be used for radiography, fluoroscopy, and for a variety of other clinical applications. It includes the firm’s Dynamic MUSICA image processing algorithms that suppress image noise, provide brightness optimization, and reduces veiling glare. There are a number of tools to (Read more...)
iSchemaView’s RAPID CTA for Brain Angiography Imaging
iSchemaView, of Redwood City, California, won FDA clearance for its RAPID CTA imaging software for CT angiography. The package helps to visualize and analyze brain vasculature, including highlighting areas of lower than normal vessel density and providing 3D tools such as rotation and zoom to give a better idea of the relevant anatomy. Product page (Read more...)
Fluorescent Particles Bind to Cancer Cells to Spot and Diagnose Tumors
Mammograms have become extremely useful in identifying suspect lesions that may be cancer, but biopsies are still required to actually find out whether the tissue is cancerous. Researchers at University of Michigan have developed a molecule, which can be delivered in pill form, that connects to cell surface receptors on certain types of cancer cell (Read more...)
Noninvasive Brain Tumor Biopsy Using Focused Ultrasound
Unlike many other tumors, ones found in the brain are usually too dangerous to take biopsies of. Now the researchers at Washington University School of Medicine in St. Louis came up with a revolutionary new way of using focused ultrasound to get tumors to release biomarkers that can then be spotted using blood samples. Thanks to […]
Shockwave’s S4 Catheter Shakes Calcified Plaque Off Peripheral Arteries
Shockwave Medical, out of Freemont California, won European regulatory approval to introduce its Shockwave S4 Peripheral Intravascular Lithotripsy Catheter. The catheter can be used to work on arteries below the knees, shocking them with ultrasound to displace plaque compacted to the vessel walls. The frequency of the ultrasound is tuned to the res (Read more...)
Terumo Releases a Narrower Stent-Graft for TEVAR Procedures
Terumo is launching in Europe its RelayPro Thoracic Stent-Graft System, initially being released to a limited set of institutions with wider availability expected soon.

4Dx Uses Algorithms to Better Visualize Lung Function
Chronic obstructive pulmonary disease affects millions of people in the United States. The main method of diagnosis is the pulmonary function tests (PFTs), in which a patient breathes into a machine that measures pulmonary parameters. The disadvantage, however, is that pulmonary function tests take an “average” of a patient’s lung (Read more...)
