Researchers at Washington University in St. Louis have developed a diagnostic method involving photoacoustic imaging, a technique that combines ultrasound and laser light. The development may allow clinicians to diagnose ovarian cancer earlier, helping to save lives. “When ovarian cancer is detected at an early, localized stage – stage 1 or 2 – the five-year […]

FDA Clears Canon’s Vantage Orian 1.5 Tesla MRI
Canon Medical won FDA clearance to bring to the U.S. market its brand new Vantage Orian 1.5 Tesla MRI scanner. It features a wide 71 centimeter bore and quiet operation thanks to its Pianissimo and Pianissimo Zen technologies. Pianissimo makes all scanning sequences quieter, while Pianissimo Zen allows certain scans to be performed at near […]
REVA’s Fantom Encore Thin Strut Bioresorbable Scaffold Unveiled
REVA Medical, out of San Diego, California, has released its Fantom Encore bioresorbable scaffold. The implant is made with the company’s own Tyrocore polymer that is absorbed by the body over a period of some months, eventually disappearing while native tissue takes over. The process helps to make sure that the lumen stays open while cells grow […]
Medtronic’s Valiant Navion Thoracic Stent Graft Cleared in EU
Medtronic won European CE Mark approval to introduce its Valiant Navion thoracic stent graft for treating lesions within the descending thoracic aorta such as thoracic aortic aneurysms (TAA), blunt traumatic aortic injuries (BTAI), and penetrating atherosclerotic ulcers (PAU). The system received FDA approval in October of this year. The Valiant Navion is particularly beneficial for patients […]
PerQseal Absorbable, Sutureless Large-Bore Closure Device Coming to Europe
Vivasure Medical, a Galway, Ireland company, is launching in Europe its PerQseal closure device for use in large vessel femoral arteriotomies following large-bore transcatheter procedures, such as aortic valve replacements. Though minimally invasive transcatheter procedures have revolutionized cardiovascular care, closing the access sites created for them can be challenging. The PerQseal device is sutureless and, once placed, […]
University of Missouri Research Reactor Now Supplying Iodine-131 for Thyroid Treatment
Medical radioisotopes are widely used in cancer treatment, but their production has been hampered to the point that obtaining them has become a challenge. The lack of Technetium-99m is probably the most widely known, but there’s also a shortage of Iodine-131 (I-131), a radioisotope commonly used for diagnosing and treating thyroid conditions because the thyroid absorbs […]
Cios Spin Mobile 3D C-Arm for Orthopedic Surgery
Siemens Healthineers has unveiled a new mobile C-arm, the Cios Spin, that can provide both 2D and 3D imaging in just about any operating room. Mostly intended for orthopedic procedures, the device allows clinicians that are currently using 2D C-arms to upgrade to 3D capability and see things in a much more intuitive perspective. Positioning […]
MRI Used to Study How Beatboxers Make Sounds
Beatboxers can make some pretty wild sounds, from deep bass thumps to snare drum cracks. How they do it is very much a mystery because the vocal chords and everything around them is hidden behind layers of tissue. Researchers at University of Southern California are using an MRI scanner to study this matter with the help […]
MRI Helps to Optimize Vagus Nerve Stimulation for GI Conditions
Vagus nerve stimulation to address various gastrointestinal conditions is already an approved FDA therapy. While effective in many people, it is hard to understand the mechanism of such treatment and to tune it well for each individual patient. Researchers at Purdue University are now utilizing MRI scanning to actually see what effect nerve stimulation has […]
HoloLens Used to Looks at Heart Scars in High Resolution
At the Beth Israel Deaconess Medical Center in Boston, researchers have been investigating the use of the Microsoft HoloLens augmented reality headset for visualizing myocardial scars during surgical interventions. During ablations and other electrophysiology procedures, the surgeon must have a good idea of where scars and other relevant items are within the heart. Typically, this […]
Optoacoustic Guidewire System for Breast Cancer Localization
Breast lumpectomy for breast CA is an imprecise procedure that too often results in cancerous tissue being left behind. About a quarter of patients have to come back and go through the surgery yet again. This is in large part due to the fact that guidewires are the standard way to point to the location […]
Philips Unveils New Radiation Oncology Imaging Systems
Philips is releasing a couple new systems for radiotherapy at the American Society for Radiation Oncology’s (ASTRO) annual meeting in San Antonio, Texas. The Big Bore RT is a dedicated CT oncology simulator with built-in technologies such as iterative model reconstruction (IMR) for improved imaging of small details and for quick completion of reference protocols. […]
FDA Approves Valiant Navion Thoracic Stent Graft for Patients with Narrow Iliac Arteries
Medtronic received FDA approval for its Valiant Navion thoracic stent graft, a minimally invasive system for correction of lesions within the descending thoracic aorta, particularly in patients with narrow iliac arteries. The device is indicated in thoracic aortic aneurysms (TAA), blunt thoracic aortic injuries, penetrating atherosclerotic ulcers, intramural hematomas, and aortic type B dissections. Patients with […]
FUJIFILM Unveils CT Scanner with Ultra-Wide Bore for Radiology, Radiotherapy
For the clinicians working on the front lines of the obesity epidemic, FUJIFILM is releasing in the U.S. a new wide-bore CT scanner, which is available in either 64 or 128 slice configurations. The FCT Embrace can be used for radiology, as well as in oncology applications, thanks to its built-in radiotherapy planning features. The […]
Siemens Releases New MRI and PET/CT Scanner for Radiation Therapy Planning
At the American Society for Radiation Oncology annual meeting, Siemens Healthineers has unveiled its RT Pro edition for Biograph Vision PET/CT scanner and MAGNETOM Sola 1.5 Tesla MRI machine to help with radiation therapy planning. Both systems are specifically designed to aid in planning of radiotherapy procedures and each features some major improvements over previous devices. The RT […]
Automated System Rates Breast Density on Mammograms
Nearly half of women have dense breasts, a risk factor for breast cancer. For proper screening, spotting dense breast tissue is important, as it can hide the presence of tumors. Currently, dense tissue is identified by radiologists viewing mammography images, but their evaluations are subjective and therefore can vary from physician to physician. A team […]
TSP Crosser for Transseptal Puncture and Left Atrial Navigation Cleared by FDA
Transseptal Solutions, a firm based in Israel, has been given clearance to introduce its flagship TSP Crosser Transseptal Access System in the U.S. The device is used to provide a path and to deliver catheters into the left atrium of the heart. Most minimally invasive cardiology procedures have been performed on the right side of […]
GE Healthcare Unveils New Automated Breast Ultrasound for Dense Breasts
GE Healthcare is unveiling its brand new Invenia Automated Breast Ultrasound (ABUS) 2.0 in the U.S. It is the only FDA approved “ultrasound supplemental breast screening technology,” which allows for spotting of cancerous lesions within dense breast tissue, according to GE. Since dense breast tissue is similar in density to tumors, the two can be […]
Tiny New Endoscope for Looking Inside Blood Vessels
Cambridge Consultants, a UK firm, and OmniVision, based in California, have developed an impressive intravascular camera. It produces native images at 400 x 400 pixel resolution, considerably better than existing fiber-optic angioscopes, but engineers at Cambridge Consultants believe this can be boosted to 1,600 x 1,600 with its own software technique that “harnesses deep learning […]
B-Laser, The First 355nm Laser for Peripheral Artery Disease Cleared by FDA
Eximo Medical, based in Israel, won FDA clearance for its B-Laser Atherectomy System that’s used to clear out plaque from within narrowed peripheral arteries, including in cases of in-stent restenosis. The laser operates at a 355nm wavelength, the only one of this kind, and the company believes that this wavelength has benefits over the commonly […]
