Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Gore provides update on REDUCE Clinical Study of HELEX Septal Occluder for PFO closure

W. L. Gore & Associates (Gore) today provided an update on the Gore REDUCE Clinical Study, a prospective, randomized, multi-center, multi-national trial designed to demonstrate safety and effectiveness of the GORE HELEX Septal Occluder for Patent Foramen Ovale (PFO) closure in patients with history of cryptogenic stroke or imaging-confirmed Transient Ischemic Attack (TIA). The unique study, which includes up to fifty investigational sites in the U.S., Denmark, Finland, Norway and Sweden, is on track to meet its estimated completion in 2015.

Early knowledge of HCC response to TACE determines treatment success: Research article

Early knowledge of hepatocellular carcinoma response to transcatheter arterial chemoembolization is crucial for determining treatment success, timing of repeat treatment, and patient prognosis. Currently, magnetic resonance imaging is used 1-3 mo after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement. Alternatively, diffusion-weighted imaging can be used as a functional imaging technique to depict thermally induced motion of water molecules.

Report: Health spending outpaces economic growth in wealthy countries

Reuters on a report from the Organisation for Economic Cooperation and Development: The increase in health spending is "piling pressure budgets already hit" by the recession and is "likely to continue rising as populations age, technology improves and public expectations grow. ... Given the urgent need to reduce their budget deficits, many OECD governments will have to make difficult choices to sustain their healthcare systems: curb the growth of public spending on health, cut spending in other areas, or raise taxes," according to the report.

Cartilage loss plays a role in development of OA, study says

A recent study determined that bone area predicted the development of medial (inner side) and lateral (outer side) knee cartilage damage and loss of medial cartilage volume. Subchondral bone mineral density (BMD) was associated with medial defect development but not cartilage loss. Researchers believe subchondral bone changes and loss of cartilage contribute to the development of osteoarthritis (OA).

Ultrasound-guided diffuse optical tomography holds promise for ascertaining early-stage invasive breast cancer

By combining two relatively inexpensive technologies based on sound and light waves, researchers hope to lower the rate at which women undergo breast biopsies for suspicious lesions. Results of the study on ultrasound-guided optical tomography are published in the online edition and the August print issue of Radiology.
