The University of Oxford has installed Siemens Healthcare's Magnetom 7T whole-body MRI system, and plans to use the system for clinical neuroscience and cardiology research.
The American College of Radiology (ACR), AdMeTech Foundation and European Society of Urogenital Radiology (ESUR) have formed a joint effort to expedite development of standards for the Magnetic Resonance Prostate Imaging Reporting and Data System (MR PI-RADS) modeled after a successful effort in breast cancer care.
Physicists from the Joint Quantum Institute (JQI), a collaborative venture of the National Institute of Standards and Technology (NIST) and the University of Maryland, have developed a theory that uses a nanomechanical membrane like a nano-sized loudspeaker to detect weak electrical signals and cool electrical circuits used in MRI.
The use of MRI in the treatment of lower back pain has been shown to do little to improve patient outcomes, and a study published online on Dec. 12 in the
Archives of Internal Medicine confirmed that finding as researchers demonstrated that a MRI performed before an epidural steroid injection doesn’t improve patient outcomes and does little to help physician decision making.

A method of classifying brain atrophy patterns in Alzheimer's disease patients using MRI can detect cognitive decline in Parkinson's disease, according to a study published online Nov. 21 in the neurology journal
Brain.
Concerns about radiation dose and the introduction of new wide-bore options have reinvigorated the MRI market, according to a report from Orem, Utah-based market researcher KLAS.
GE Healthcare showcased advances across its portfolio at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) in Chicago Nov. 27 to Dec. 2. New launches included interventional and cardiovascular x-ray systems, MR enhancements and technologies to address radiation exposure.
Toshiba’s showcase at the annual meeting of the Radiological Society of North America (RSNA) in Chicago Nov. 27 to Dec. 2 included its new Vantage Titan 1.5T MR series and Aplio 300 and 500 ultrasound systems. Rounding out its lineup of new offerings were its Adaptive Iterative Dose Reduction 3D (AIDR 3D) software, and Dual Energy and Myocardial Perfusion functional-CT applications.
Royal Philips Electronics has received 510(k) clearance from the FDA for its whole-body PET/MR imaging system, the Ingenuity TF PET/MR. The system was on display at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), Nov. 27 to Dec. 2.
CHICAGO—The implementation of clinical decision support resulted in a marked, positive change in the utilization pattern for breast MRI, according to a study presented Nov. 30 at the Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
CHICAGO—With the number and frequency of incidentalomas on the rise, researchers have sought to quantify the economic impact of the finding and reported that followup can potentially double the cost of the index study depending on the frequency of the finding and the type of followup, according to a presentation on Nov. 30 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America.
CHICAGO–Despite a wide perception that radiologists should make and record recommendations for additional testing to avoid malpractice, the data indicate that outside of breast radiology, failure to recommend an additional test as a primary allegation is very rare, according to Kim S. Clarkin, MD, of New Jersey Medical School in Newark, during a session on Nov. 28 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
CHICAGO--Image interpretation will need to include quantitative analysis in the future, according to a session on Nov. 30 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).

CHICAGO--Treating patients as VIPs, personal greetings from radiologists and a spa-like atmosphere are the hallmarks of patient-centered radiology facilities, according to a presentation on Nov. 29 at the 97th Scientific Assembly and Annual Meeting of the Radiology Society of North America (RSNA). Using his own facility as an example, Volney Van Dalsem, MD, medical director of outpatient imaging at Stanford University in Stanford, Calif., provided some concrete suggestions for making an imaging facility more patient-centered.
CHICAGO--As hospitals continue to focus on incorporating evidence-based guidelines into radiology, departments must first understand their desired outcomes and their audience, according to a presentation on Nov. 29 at the 97th Scientific Assembly and Annual Meeting of the Radiology Society of North America (RSNA).
CHICAGO—In the era of the prostate-specific antigen (PSA) screening, imaging has played a supporting role in combating prostate cancer, though that could be changing as the use of prostate MRI becomes more common, according to a presentation on Nov. 28 at the 97th Scientific Assembly and Annual Meeting of the Radiology Society of North America (RSNA).
CHICAGO – Mechanistic imaging, which leverages imaging to understand the pathophysiology of disease, will project the specialty of radiology another leap forward, said A. Gregory Sorensen, MD, co-director of Martinos Center for Biomedical Imaging at Massachusetts General Hospital in Boston and CEO of Siemens Healthcare USA, during the Pendergrass New Horizons Lecture Nov. 28 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
CHICAGO—Outlining how to avoid patient harm and subsequent litigation in MR procedures, presenters of a Nov. 27 session during the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) stressed taking patient safety into one’s own hands. Emanuel Kanal, MD, Pittsburgh, and Craig E. Frischman, Esq., Pittsburgh, described a number of “slam dunk” cases for prosecutors, where patients were harmed during imaging procedures and radiologists were found responsible. The incidents ranged from oversights and outright negligence to horrific accidents.
CHICAGO—While appropriate use criteria are key to curbing radiation exposure and ensuring beneficial CT exams, clinicians have not yet embraced them. Despite the lukewarm acceptance of appropriateness criteria, James A. Brink, MD, chair of radiology at Yale University Medical Center in New Haven, Conn., upped the ante and called for development of multidisciplinary diagnostic algorithms to standardize image utilization during a session on Nov. 27 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
CHICAGO—Technologist performed handheld screening breast ultrasound offered to women with heterogeneous or dense breasts can detect small mammographically occult breast cancers with a cancer detection rate of 0.32 and a cost of $55,000 per breast cancer, according to a retrospective review presented Nov. 27 at the 97th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA). However, the overall positive predictive value of screening ultrasound is low.
