CT, MRI use declined in ED after 2007
August 20, 2014 -- After a period of rapid increase from 1993 to 2007, use of medical imaging in the emergency department (ED) declined, mostly because of decreased utilization of CT and MRI, according to a new study published this month in the American Journal of Roentgenology.
MRI points to brain benefits of exercise for kids
August 20, 2014 -- Diffusion-tensor MR images have confirmed that aerobically fit children have more favorable white-matter tracts in their brains than their less fit peers, thus improving their chances for greater cognitive function.
MRI histogram analysis predicts bladder tumor aggressiveness
August 15, 2014 -- Sophisticated histogram-based measurements of diffusion on MRI scans can predict bladder tumor aggressiveness noninvasively, according to a new study in Abdominal Imaging. The results could potentially help clinicians tailor therapy to individual patients, and even help predict which patients' tumors will metastasize.
MRI finds 2nd cancers after breast conservation therapy
August 14, 2014 -- Women who have had breast conservation therapy have an increased risk of developing second breast cancers, and they require careful tracking. But which modality is most effective? MRI, according to a new study published in Radiology.
MRI tracks early brain development in newborns
August 12, 2014 -- For the first time, researchers are using MRI to calculate the volume of multiple brain regions in newborns to investigate how those areas develop based on gender, gestational period, and other factors in the first 90 days of life.
Canadian policy to improve MRI referrals has mixed results
August 7, 2014 -- A campaign by the Ontario Ministry of Health to reduce inappropriate referrals for lumbar MRI resulted in more-appropriate exams, but it did not lower the number of new referrals, according to a study published in the August issue of the Journal of the American College of Radiology.
Pilot study shows PET/MRI's benefits for large-vessel vasculitis
August 7, 2014 -- Evidence supporting the clinical value of PET/MRI continues to mount, as a small study from Germany has found that the hybrid modality is effective for evaluating patients with large-vessel vasculitis.
Honey, I shrunk the magnet: Preclinical 7T MRI runs cryogen-free
July 25, 2014 -- Looking to fill a void in the market for preclinical MRI and eliminate the need for labs to hunt down scarce supplies of liquid helium, MR Solutions has developed a new cryogen-free, compact 7-tesla preclinical scanner for research applications.
MRI links antipsychotic drugs to brain loss
July 21, 2014 -- MR images of patients with schizophrenia have confirmed that antipsychotic drugs can lead to a decrease in brain volume, but the drugs do not appear to cause adverse cognitive issues. The study also found that the rate of brain loss was greater when the dose of medication was higher.
MRI safety remains a concern, as does need for more formal training
July 14, 2014 -- The number of adverse MRI events continues to be a serious issue for imaging centers and radiology departments, despite mandates and guidance to implement MRI safety measures from organizations such as the American College of Radiology and the Joint Commission.
MRI use linked to patient mortality in Irish study
July 9, 2014 -- A new study of MRI use at a hospital in Ireland paints a complex picture of the modality, with higher in-hospital mortality and longer hospital stays for patients who got MRI scans. However, this could be because the patients were more acutely ill, according to an article in the July Journal of the American College of Radiology.
Native American, rural women have less access to breast MRI
June 27, 2014 -- Most U.S. women have relatively easy access to mammography and breast ultrasound, but breast MRI presents a greater challenge, especially for Native American women and those in rural areas, according to a new study published online in the Journal of the American College of Radiology.
GE lifts covers on prototype of compact MRI brain scanner
June 27, 2014 -- With an eye toward improving the early diagnosis of neurological disorders such as Alzheimer's disease, GE Healthcare this week revealed that it is developing a compact 3-tesla MRI scanner designed specifically for head and brain imaging.
4-scan PET/MRI exams improve breast imaging
June 25, 2014 -- Austrian researchers added PET/CT to a package of three MRI sequences to create fused PET/MR images, which they found aided in the differentiation of suspicious breast lesions, according to a new study published online in Clinical Cancer Research.
MRI technique and iron level could help diagnose ADHD
June 17, 2014 -- Using an MRI technique called magnetic field correlation, researchers can measure brain iron levels in adolescents, which could help diagnose attention-deficit/hyperactivity disorder (ADHD) and lead to more effective treatment. Study results were published online June 17 in Radiology.
SNMMI: PET, MRI may predict pediatric brain tumor outcomes
June 11, 2014 -- ST. LOUIS - Researchers from Boston Children's Hospital have found that certain PET and MR imaging characteristics of brain tumors in pediatric patients may help predict progression-free and overall survival, according to a study presented on Tuesday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting.
MRI finds brain abnormalities in late preterm infants
June 10, 2014 -- Using MRI, Australian researchers found smaller brain size and other abnormalities that could lead to long-term developmental issues in babies born 32 to 36 weeks into gestation, according to a study published online June 10 in Radiology.
PET/MRI holds its own for esophageal cancer staging
June 2, 2014 -- The benefits of PET/MRI may be expanding to esophageal cancer, according to a study published online May 27 in the Journal of Nuclear Medicine. Korean researchers found that the hybrid modality matched endoscopic ultrasound for staging tumors.
When should imaging be used for sports-related injuries?
June 2, 2014 -- When an athlete is injured, the first instinct is likely to order an MRI, CT, x-ray, or ultrasound exam to determine the extent of the damage. However, such use of a potentially unnecessary and expensive scan can ignite debate among general practitioners, orthopedic and neurologic specialists, and radiologists.
Radiologist training tool improves MSK interpretations
May 21, 2014 -- A new teaching tool called Real View Radiology is showing early success by improving the ability of first- and second-year residents to interpret musculoskeletal MRI cases. The system was developed by a group of residents at IU Health, the health system affiliated with Indiana University (IU).
MRI shows smaller hippocampus among football players
May 13, 2014 -- MRI scans uncovered smaller hippocampal volumes among collegiate football players with a history of concussion or who had played for more years than their teammates, in a study published in the May 14 issue of the Journal of the American Medical Association.
