Chinese MRI researchers arrested on conspiracy, bribery charges
May 21, 2013 -- Federal authorities have arrested Chinese researchers who worked on MRI technology at NYU Langone Medical Center for allegedly acquiring research money from the U.S. government and then sharing technological information with a Chinese company and government-sponsored research institute in China.
GE to ship MRI protocol for patients with metal implants
May 16, 2013 -- GE Healthcare on May 15 said it plans to begin shipping MAVRIC SL, a combination of MRI acquisition protocol and postprocessing software designed to enhance the accuracy of soft-tissue and bone imaging in patients with metal implants that could make them unsuited for MRI with conventional techniques.
Simultaneous PET/MRI most accurate for image alignment
May 15, 2013 -- In a comparison of hybrid imaging modalities, simultaneous whole-body PET/MRI is more accurate than retrospectively fused PET and MR images in abdominal organs and better than PET/CT in the urinary bladder, according to a study published online May 8 in Radiology.
Volumetric MR images boost cervical cancer treatment planning
May 13, 2013 -- Three-dimensional volumetric MR images of cervical disease yield a bounty of critical information, enabling precise planning of brachytherapy for residual tumors, according to researchers from St. Joseph's Hospital and Medical Center in Phoenix.
Study shows feasibility of cardiac PET/MRI -- with caveats
May 9, 2013 -- Cardiac FDG-PET/MRI is feasible on an integrated whole-body PET/MRI system, but the hybrid modality still must prove it adds clinical relevance to cases of ischemic heart disease, according to a study published online May 7 in Radiology.
ASBS: Breast MRI helps assess patient prognosis
May 8, 2013 -- MRI evaluation following breast cancer diagnosis can improve a woman's long-term prognosis, as the modality is able to detect lymph-node metastases associated with poorer outcomes, according to research presented on May 3 at the American Society of Breast Surgeons (ASBS) annual meeting in Chicago.
Breast MRI changes cancer treatment in many women over 60
May 3, 2013 -- A new study led by Dr. Stamatia Destounis found that women older than 60 years saw changes to their initial cancer treatment plan approximately 50% of the time after undergoing MRI to determine the extent of disease.
MRI shows rotator cable's influence in rotator cuff injuries
April 30, 2013 -- Using MRI, researchers at NYU Langone Medical Center believe they have taken an important first step in understanding the rotator cable's role in both intact and torn rotator cuffs, which, in turn, could improve characterization of a patient's injury or disease.
MRI adds to cancer detection in women with breast implants
April 25, 2013 -- When used as an adjunct to mammography and ultrasound, MRI can find additional cancers and provide more detail about their location in patients with breast implants, according to a study from Memorial Sloan-Kettering Cancer Center.
MRI shows brain atrophy's potential link to multiple sclerosis
April 23, 2013 -- MR images show that when the thalamic and central regions of the brain atrophy, individuals have a greater chance of developing multiple sclerosis over the course of two years, according to a study published online April 23 in Radiology.
Postmortem MRI shows sudden cardiac death invisible at autopsy
April 17, 2013 -- In results that add substantial forensic power to identifying the cause of death, postmortem cardiac 3-tesla MRI has been found to identify sudden cardiac death in cases that are invisible at conventional autopsy, according to new research published online in the Journal of the American College of Cardiology.
JACR: MRI use has slowed
April 8, 2013 -- The overall Medicare MRI utilization rate has slowed since 2008, due in part to policymakers' focus on reducing unnecessary healthcare costs -- and radiologists' efforts to educate their colleagues on appropriate imaging use, according to a new study published online in the Journal of the American College of Radiology.
Imaging centers hit with surprise 30% cut for MRI codes
April 5, 2013 -- The American Taxpayer Relief Act in January averted the planned 26.5% cut to the Medicare Physician Fee Schedule, but it didn't prevent reimbursement for two "bread and butter" MRI codes from being slashed by 30%. Some freestanding imaging centers are only now becoming painfully aware of the cut.
MRI helps guide appendicitis assessment in pregnant women
April 2, 2013 -- MRI without oral contrast is useful for evaluating pregnant patients suspected of having appendicitis and should be used as an adjunct imaging test in their clinical workup, according to a study published in the April issue of Radiology.
MRI spots brain abnormalities in patients with migraines
March 26, 2013 -- Using a surface-based MRI method to measure cortical thickness, Italian researchers have found that migraine headaches may be related to brain abnormalities present at birth and other abnormalities that develop over time, according to a study published online in Radiology.
JAMA IM: Lumbar spine MRI scans substantially overused
March 25, 2013 -- Canadian researchers have found evidence of "substantial overuse" of lumbar spine MRI scans: More than half of requests for images were considered inappropriate (29%) or of uncertain value (27%) in a study published online March 25 in JAMA Internal Medicine.
DWI-MRI assists proton beam therapy for ocular melanoma
March 22, 2013 -- The ability of diffusion-weighted MRI (DWI-MRI) to differentiate between ocular melanoma and retinal detachment can help direct the appropriate proton beam therapy for patients, according to a study presented at this month's European Congress of Radiology.
Automated postprocessing tools improve cardiac MR scans
March 21, 2013 -- Several image postprocessing methods are up for the task of assessing myocardial scar tissue from late gadolinium enhancement on cardiac MR exams, according to a multicenter study presented at the recent Society for Cardiovascular Magnetic Resonance meeting.
ACC: Nonthoracic MRI may be safe for pacemaker, ICD patients
March 13, 2013 -- SAN FRANCISCO - Nonthoracic MRI scans are safe for patients with cardiac pacemakers or implantable cardioverter defibrillators (ICDs), according to preliminary results from the MagnaSafe Registry presented on March 10 at the 2013 American College of Cardiology (ACC) meeting.
