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.
ARRS: Pulmonary MRI feasible for evaluating acute PE
May 8, 2014 -- SAN DIEGO - Pulmonary MRI can be used to evaluate acute pulmonary embolism (PE), offering an alternative for patients who can't undergo CT pulmonary angiography or are allergic to iodinated contrast agents, according to research presented by a Turkish group at the American Roentgen Ray Society (ARRS) annual meeting.
Algorithm spots changes in follow-up brain MRI studies
May 7, 2014 -- Detecting changes in follow-up imaging studies can be difficult due to technical factors as well as human error. A software algorithm developed by a Canadian research team may be able to provide radiologists with some assistance.
DTI-MRI shows men recover more slowly from concussions
May 6, 2014 -- Gender appears to affect how long it takes someone to recover from a concussion, according to diffusion-tensor MRI (DTI-MRI) results. Young men demonstrated longer recovery times than women in a study published online May 6 in Radiology.
Functional MRI finds abnormal brain regions in ADHD youth
May 5, 2014 -- Resting-state functional MRI has uncovered new abnormalities in key brain regions in children and adolescents with attention-deficit/hyperactivity disorder (ADHD), according to a study from China published online April 30 in Radiology.
MRI shows that diabetes leads to loss of brain volume
April 30, 2014 -- MRI results suggest that the longer a patient has type 2 diabetes, the more brain volume is lost, according to research published online April 29 in Radiology. This was especially true for gray matter, which is associated with speech, motion, and memory.
MRI finds loss of brain volume in older, apathetic adults
April 17, 2014 -- MRI scans have revealed that older adults with bouts of apathy may have smaller volumes of gray and white matter in areas of the brain associated with learning, memory, and internal communication, according to a study published online April 16 in Neurology.
DTI-MRI sheds light on mild traumatic brain injury
April 15, 2014 -- Researchers using diffusion-tensor MRI (DTI-MRI) believe they have identified parts of the brain that cause people with mild traumatic brain injury to become dizzy or have vision problems, according to a study published online April 15 in Radiology.
