World’s First PET/SPECT Scanner Developed Using Compton Camera
Nuclear medicine relies on two imaging modalities to assess internal function and diagnose disease. Positron emission tomography (PET) typically uses fluorine-18, a radiotracer that releases positrons, and a special scanner to detect the resulting gamma rays. Single-photon emission computed tomography (SPECT) is similar, but usually depends on inje (Read more...)
LipoGlo Makes Bad Cholesterol Glow Inside Zebrafish
So-called “bad cholesterol” is a molecular complex of fat and protein. Specifically, the protein is Apolipoprotein-B, or ApoB, and the fat is cholesterol. While ApoB helps fat molecules to move around the blood vasculature, it is also what makes cholesterol stick to vessel walls, forming dangerous plaques that are one of the main causes (Read more...)
3D Printed Titanium Implants for Severe Spinal Deformities
Most medical implants are manufactured in quantity to cover large groups of people suffering from specific diseases. Those with rare conditions are often left out, but 3D printing, also known as additive manufacturing, now allows for the production of bespoke devices designed exclusively for individual patients. While 3D printing technology has adv (Read more...)
Samsung Launches iQuia Digital Radiography Platform

CompCyst Tool Developed to Identify Precancerous Cysts
Researchers from Johns Hopkins Kimmel Cancer Center have developed a new computational and biomolecular tool, dubbed CompCyst, that can identify precancerous pancreatic cysts. The technology provides a new method for reliably identifying cancer-causing cysts from those that are not cancer-causing. The teams work demonstrates that in over half of pa (Read more...)
Penumbra Unveils JET 7 with XTRA FLEX Mechanical Stroke Remover
Penumbra is releasing a new stroke thrombectomy aspiration system at the Society of NeuroInterventional Surgery 16th Annual Meeting in Miami. The Penumbra JET 7 Reperfusion Catheter with XTRA FLEX technology is designed to be compatible with the Penumbra ENGINE, a device that generates the vacuum necessary to suck out thrombi from within the brain. (Read more...)
Looking Deep Into Body Using Virtual Ultrasound Lens
Light is a great tool for imaging the outside of the body and for looking at the interior using endoscopes, but looking through more than a few millimeters of tissue typically requires other modalities such as X-rays and ultrasound. Using light to peer through skin, muscle, and other soft tissues has remained an elusive goal […]
ProFound AI for 2D Mammography Cleared in Europe to Spot Potential Breast Tumors
iCAD, a company based in Nashua, New Hampshire, won European CE Mark approval for its ProFound AI for 2D Mammography software system. The product relies on a “high-functioning, deep learning” artificial intelligence algorithm to analyze 2D mammography scans and point out potential areas of concern. The software package provides “C (Read more...)
INSIGHTEC Neuro with GE 3 Tesla MRI Now Approved in U.S., Europe
INSIGHTEC, an Israeli firm, and GE Healthcare have won FDA approval and the European CE mark for the Exablate Neuro with the SIGNA Premier MRI. The Exablate Neuro, made by INSIGHTEC, delivers focused ultrasound into the brain as a treatment option for Parkinson’s, essential tremor, and neuropathic pain (the last indication appropriate only to (Read more...)
Centerline’s Radiation-Free IOPS System for Minimally Invasive Procedures
Centerline Biomedical, a company based in Cleveland, Ohio, landed FDA clearance for its Intra-Operative Positioning System (IOPS). The product provides physicians with a radiation-free way to navigate through vasculature during minimally invasive procedures. Currently, X-ray fluoroscopy is used to track where minimally invasive instruments are in a (Read more...)
Harmonic Nanoparticles for Theranostic Applications
Researchers from Ecole Polytechnique Fédérale de Lausanne in Switzerland have developed new nanoparticles for theranostic (therapeutic and diagnostic) applications. Their work describes the synthesis of these particles and demonstrates that by stimulating at a long, safe wavelength, the nanoparticles can cleave bonds that hold onto dr (Read more...)
Five Day Long Scan of Complete Brain Using Ultra Powerful MRI
Two years ago the FDA issued the first clearance for a high-field MRI scanner, the Siemens MAGNETOM Terra. Featuring a 7 Tesla magnet, the device generates a magnetic field more than twice the strength of the 3 Tesla scanners that were previously the most powerful for clinical use. Now, a team of researchers, headed by […]
NuVasive Releases Pulse Spinal Surgical System
NuVasive, a company based in San Diego, California, is releasing its Pulse system. The product combines a number of technologies, including neuromonitoring, global alignment, rod bending, imaging with radiation reduction, and navigation, to help surgeons perform spinal procedures.

Blood Flow Measurement Using Tiny LED Catheter
Measuring blood flow is important during a variety of surgical procedures, as well as in intensive care settings. Typically, this is performed intermittently, so there’s not a lot of temporal detail in the readings. Now, a team of researchers at Flinders University in Australia has developed a proof-of-concept prototype vascular catheter that (Read more...)
New Mini-MRI Prototype to Maximize Image Quality and Patient Comfort
Scientists at Imperial College London have developed a “mini-MRI” scanner prototype that they believe will change the way clinicians diagnose knee injuries. The research, recently published in the journal Magnetic Resonance in Medicine, describes accurate visualization of the knee joint anatomical structures in animal trials. The protot (Read more...)
