Low-Field MRI for New Imaging Possibilities, Fewer X-rays

Researchers at the Ohio State University Wexner Medical Center are using a new low-field MRI system that may expand the capabilities of MRI for patients with implanted devices, patients who require lung imaging, and obese patients. The system, which was developed in a collaboration between Siemens and Ohio State, has a magnetic field strength of [& (Read more...)

Wearable Helmet for Non-Invasive Optical Brain Imaging

Kernel, a medtech company based in California, has developed the Kernel Flow, a wearable helmet that can perform time domain functional near-infrared spectroscopy (TD-fNIRS) imaging of the brain. The system has a smaller footprint, is less expensive and less complex than benchtop TD-fNIRS systems, but has demonstrated similar imaging performance. T (Read more...)

Soft X-Ray Tomography for Quick 3D Imaging of Cell Organelles

Researchers at Heidelberg University in Germany used an imaging technique called soft X-ray tomography to obtain highly detailed 3D images of the interior of cells, including changes that occur when the cell is infected with SARS-CoV-2. The approach can provide a high-resolution 3D image in minutes, which is much faster than other microscopy techni (Read more...)

3D Blood Vessel Map Reveals Location of Stem Cells

Scientists at Johns Hopkins used a combination of molecular labeling and imaging techniques to create a three-dimensional map of the blood vessels in the mouse skull. Their approach also reveals niches where stem cell populations lurk, which could help researchers to understand how blood vessels and cells behave in various states of disease or inju (Read more...)

Fish-Shaped Microrobots to Deliver Chemotherapy to Tumors

Researchers from the University of Science and Technology of China, working with outside collaborators, have developed shape-shifting microrobots that are designed to be guided to a target area in the body using magnets, and then release a drug cargo in response to the local environment. The application that the researchers have pursued involves gu (Read more...)

Cracking Calcium in Arteries Using Sound Waves: Interview with Shockwave Medical’s Scott Shadiow

Shockwave Medical, a medtech company based in California, has developed a technique called intravascular lithotripsy, which involves delivering sonic waves to calcified plaque in an artery in much the same way that sound waves have been used to treat kidney stones for many years. The idea is to safely crack the calcified deposits so that […]

Steerable Catheter to Navigate Tortuous Blood Vessels in Brain

A team at University of California San Diego invented a way to make steerable catheters that can more precisely navigate the tortuous architecture of the brain vasculature. The device was bioinspired by delicate structures found in nature, including flagella and insect legs, and uses principles from soft robotics to create a hydraulic steering syst (Read more...)

Virtual Reality System to Entertain During MRI Scans

Researchers at King’s College London developed a virtual reality system that is intended to distract and calm patients who find MRI scans challenging, including children and other vulnerable individuals. The patient wears a specialized VR headset during the scan and can interact with the system merely by moving the eyes, allowing them to play (Read more...)

Ultrasound Patch Monitors Blood Flow

Researchers at the University of California San Diego created an ultrasound patch that can measure blood flow in vessels as deep as 14 cm within the body. The stretchy patch can be applied to the skin and may help clinicians to monitor and diagnose various conditions, including blockages that could cause an infarct. The patch […]

Nanoparticles for Tumor Imaging and Cancer Urine Testing

Scientists at MIT have announced that they developed novel nanoparticles to detect cancer in urine samples. As well as detecting the presence of tumors, the nanoparticles can also accumulate at tumor sites and function as an imaging agent, helping to identify their location. These multifunctional particles could be very useful for routine cancer sc (Read more...)

AI System Spots Prostate Cancer During Routine CT Scans

Researchers at RMIT University in Melbourne, Australia, created an AI system that can identify prostate cancer during routine CT scans. It is typically difficult to spot prostate cancer in CT images, and the radiation makes CT unsuitable as a screening modality. However, if men are undergoing abdominal or pelvic scans for other reasons, this latest (Read more...)
