Population-based whole-body MRI finds serious disease
March 10, 2014 -- VIENNA - Whole-body MRI screening is safe and accurate for detecting serious pathology in the asymptomatic general population -- especially in patients older than 50, according to a study presented on Sunday at ECR 2014. A few findings were more prevalent than expected in individuals younger than 50.
Multimodality vendors launch scanners at ECR 2014
March 9, 2014 -- VIENNA - In the past, ECR languished in the shadow of Chicago's RSNA show when it came to new product introductions. But ECR is slowly coming into its own, as indicated by new product launches from the major multimodality companies at this week's congress.
7T MRI may improve diagnosis of Parkinson's disease
March 5, 2014 -- Researchers in Italy used 7-tesla MRI to uncover details of an area in the brain linked to Parkinson's disease, which could help improve early detection of the condition, according to a study published online February 26 in Radiology.
MRI's view of carotid artery helps predict cardiovascular risk
March 4, 2014 -- Using MRI to image carotid artery plaque can accurately predict future cardiovascular events such as strokes and heart attacks in people with no history of cardiovascular disease, according to a new study published online March 4 in Radiology.
Short-term follow-up OK for BI-RADS 3 lesions on MRI
March 4, 2014 -- The malignancy rate is comparable for lesions detected at mammography and those found on MRI that are probably benign, which means that short-term follow-up is acceptable for women with no history of breast cancer, according to a new study published in the March issue of the American Journal of Roentgenology.
fMRI shows where musicians get improvisational skills
February 19, 2014 -- Functional MR images (fMRI) show areas of heightened activity in the brains of jazz musicians as they improvise and introduce and modify melodies in response to each other's ideas, according to new study published online February 19 in PLOS One.
Study tests safety of implantable devices with 7T MRI
February 18, 2014 -- Although the routine clinical use of 7-tesla MRI may be several years away, researchers at Vanderbilt University have begun testing implants and other items to determine how they will react when exposed to an ultrahigh-field magnet, according to a study published in the February issue of the American Journal of Roentgenology.
ACC, others call for patient-centric heart imaging
February 18, 2014 -- Noninvasive cardiovascular imaging decisions must become more patient-centric and individualized, according to a statement from the American College of Cardiology (ACC) that was endorsed by 14 other medical societies.
Tomosynthesis nearly equals MRI for rheumatoid arthritis
February 11, 2014 -- Digital tomosynthesis is nearly as good as MRI for detecting signs of rheumatoid arthritis, and both are much better than the reference standard, conventional radiography, according to a new study in the February issue of the American Journal of Roentgenology.
Report: MRI scanner installed base is long in the tooth
February 5, 2014 -- The average age of the installed base of MRI scanners in the U.S. grew from 8.7 years in 2010 to 11.4 years in 2013, meaning that many scanners could be due for a replacement, according to a new market research report by IMV Medical Information Division.
Research sheds light on why MRI CAD misses cancers
February 3, 2014 -- Despite its ability to improve the detection of breast cancer, breast MRI computer-aided detection (CAD) software still misses some. Several factors can affect the detection capabilities of the software, Korean researchers have found.
Some cardiac MRI findings predict future heart events
January 31, 2014 -- Certain MRI findings can independently predict future cardiovascular events in patients with coronary artery disease or those who recently had a heart attack, but you have to be careful which ones you choose, according to a study published online January 29 in the Journal of the American College of Cardiology.
CAD uses MRI to differentiate brain tumors on FDG-PET
January 29, 2014 -- A computer-aided detection (CAD) algorithm that makes use of anatomic data from MRI scans can help radiologists differentiate between benign and malignant brain tumors on FDG-PET images, according to researchers from Yamaguchi University in Japan.
Whole-body DWI-MRI could aid treatment of myeloma
January 29, 2014 -- Whole-body diffusion-weighted MRI (DWI-MRI) can help assess treatment response in patients with myeloma and potentially reduce the number of painful bone marrow biopsies they need to undergo, according to a study published online in Radiology.
Arab Health: Multimodality imaging key to managing breast cancer
January 27, 2014 -- DUBAI - Finding a suspicious breast lesion is just the start of the path toward optimal management and treatment of breast cancer, and multiple imaging modalities should be used, according to a talk by Dr. Rola Shaheen on the opening day of the Total Radiology sessions at Arab Health 2014.
MRI volumetry forecasts IQ decline in sickle cell disease
January 17, 2014 -- Structural MRI volumetric analysis of gray matter in the brain can predict a subsequent decline in IQ in children with sickle cell disease, according to a team from the University of Maryland School of Medicine.
Triaging hearing loss patients can help save on MRI scans
January 10, 2014 -- Using less-complex MRI scans to triage patients with hearing loss, while reserving comprehensive MRI exams for those with pathology, can save money without affecting diagnostic efficacy, according to research published in the January issue of the American Journal of Roentgenology.
MRI technologies land on ECRI's 2014 watch list
January 7, 2014 -- Nonprofit research firm ECRI Institute has included MR-guided focused ultrasound and the integration of MR images in radiation therapy on its technology watch list for the coming 12 to 18 months.
Developmental venous anomalies can be overlooked on MRI
December 26, 2013 -- Developmental venous anomalies may be the most frequently encountered cerebral vascular malformations, but they can often be overlooked on MRI findings, according to a new study from Turkey that offers some tips on identifying the conditions on MRI exams.
4T fMRI sheds light on brain activity in early Alzheimer's
December 24, 2013 -- A new study by Canadian researchers illustrates how perfusion-based functional MRI (fMRI) with a 4-tesla arterial spin labeling protocol can be used to measure brain activity in people with early-stage Alzheimer's disease while they perform memory tasks.
PET/MRI offers details in acute myocardial infarction cases
December 20, 2013 -- German researchers have concluded that simultaneous PET/MRI for patients with acute myocardial infarction is feasible after finding "good concordance" in a comparison of PET and MR images. The study was presented at the RSNA 2013 meeting earlier this month.
