April 10, 2014 -- SAN FRANCISCO - Brain changes resulting from traumatic brain injury are measurable on MRI after just one season of high school football, even if the athletes never experienced a concussion, according to a study presented on Tuesday at the American Association of Neurological Surgeons meeting.
Stress cardiac MRI aids early emergency dept. evaluations
April 7, 2014 -- When performed within 12 hours of a patient coming to an emergency department with chest pain, adenosine stress cardiac MRI is valuable for the "safe, quick, and accurate" diagnosis of significant coronary artery disease, according to a study published in the April issue of Radiology.
Cardiac MRI useful in selecting patients for liver transplants
March 28, 2014 -- Cardiac MRI is an accurate technique for evaluating changes in the myocardium of patients with end-stage liver disease, particularly those who have been infected with hepatitis C, according to a new Egyptian study presented at ECR 2014.
MRI provides alternative to CT, US for pediatric appendicitis
March 20, 2014 -- MRI without contrast provides "high diagnostic performance" for suspected pediatric appendicitis and has "substantial" agreement with ultrasound in positive appendicitis cases, indicating that it could be an alternative to both ultrasound and CT for this application, according to a study published online March 17 in Radiology.
Study finds overutilization of imaging for headache in U.S.
March 18, 2014 -- Despite guidelines to control the use of CT and MRI for headaches and migraines, neuroimaging procedures are overused and cost an estimated $3.9 billion between 2007 and 2010, according to a study published online March 17 in JAMA Internal Medicine.
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.
