MRI technique shows how energy drinks alter heart function
December 2, 2013 -- CHICAGO - Using a novel cardiac MRI technique, German researchers found significantly increased heart contraction rates in the left ventricle of healthy young adults one hour after they consumed energy drinks, in a study presented on Monday at the RSNA annual meeting.
MR spectroscopy uncovers brain differences in preterm infants
November 26, 2013 -- Using MR spectroscopy, researchers at Children's Hospital Los Angeles may have found a link between premature birth and developmental issues in the brain's white matter that could put these newborns at greater risk for problems later in life.
DTI-MRI shows brain changes in temporal lobe epilepsy patients
November 20, 2013 -- Diffusion-tensor MRI (DTI-MRI) has shown widespread, abnormal connections in the brains of patients with temporal lobe epilepsy, which could help with diagnosis and treatment, according to a new study published online November 19 in Radiology.
Breast MRI use grows, but does it benefit the right women?
November 19, 2013 -- Overall use of breast MRI has increased over the past decade, but there are concerns that the modality is overused in women who don't meet screening guidelines, while being underused in those who could benefit the most, according to two studies published online November 18 in JAMA Internal Medicine.
MRI helps home in on disabilities caused by MS
November 15, 2013 -- Abnormalities throughout the spinal cord and the number of segments affected by spinal cord lesions are the most significant MRI parameters for characterizing physical disabilities caused by multiple sclerosis (MS), according to a study published in the November issue of Radiology.
Stress cardiac MR matches 320-row CCTA results
November 1, 2013 -- Vasodilator stress cardiac MR and 320-detector-row coronary CT angiography (CCTA) both accurately detect obstructive coronary artery disease, and the two tests are also highly concordant, according to the results of a new study in the International Journal of Cardiovascular Imaging.
New breast MRI exam ready to screen women with dense breasts
October 16, 2013 -- Conventional x-ray mammography is a notoriously poor tool for screening women with dense breast tissue. Breast MRI is a possible alternative, but the cost of the exams is prohibitively high. A Michigan breast specialist believes he has changed the equation with a streamlined breast MRI screening exam that could be ready for widespread clinical use.
Sports injury website brings radiology's insights to the fans
October 15, 2013 -- Ardent sports fans can easily explain a blitz, play-action fake, suicide squeeze, and icing. What many of them can't do is describe a torn anterior cruciate ligament or plantar fasciitis. The founder of a new website, InsideInjuries.com, hopes to change that -- and in the process help educate the public about radiology.
MRA helps detect risk from unruptured cerebral aneurysms
October 15, 2013 -- MR angiography (MRA) using a 3D time-of-flight sequence could well be the most efficient technique for detecting unruptured cerebral aneurysms and determining if they pose a health risk, according to a study published in the October 15 issue of Annals of Internal Medicine.
Preoperative MRI may clarify use of radical trachelectomy
October 3, 2013 -- By measuring the distance between a tumor and a woman's internal os at MRI before surgical removal of the uterine cervix, or trachelectomy, physicians may be able to identify high-risk patients who should instead undergo a radical hysterectomy, according to a study published in the October Radiology.
Ferromagnetic detection could boost safety in MRI suite
September 30, 2013 -- A ferromagnetic detection system ferreted out many kinds of metallic devices and objects that could typically be introduced into an MRI suite, according to a study in the October issue of the American Journal of Roentgenology. Such a system could help prevent implant-related accidents, the authors concluded.
MRI software opens views to blood-flow issues, stroke potential
September 25, 2013 -- When patients experience blood-vessel blockage that could lead to a stroke, correcting the condition as soon as possible can be critical. Vascular analysis technology firm VasSol believes its software, designed to quantify blood flow through any vessel in the body, can help with this and other conditions.
Self-referral prompts unnecessary knee MRI exams
September 17, 2013 -- Knee MRI exams are more likely to be negative if ordered by physicians who have a financial interest in the imaging equipment being used, researchers concluded in a study published online September 17 in Radiology.
PET/MRI shows growing edge over PET/CT in oncology
September 17, 2013 -- FDG-PET/MRI more accurately evaluated and more often changed the management of patients with various forms of cancer in a comparison with PET/CT, according to preliminary research published online September 5 in Radiology.
Cardiac imaging unsuitable for screening asymptomatic athletes
September 16, 2013 -- Despite technological advances in imaging in recent years, a new review has concluded that cardiac imaging cannot yet be recommended as a first-line screening tool for athletes who show no obvious signs of coronary abnormalities.
ASCO BCS: Breast MRI reduces biopsies of false positives
September 11, 2013 -- SAN FRANCISCO - In experienced hands, breast MRI with mammography or ultrasound can help avoid biopsies of suspicious lesions that would otherwise turn out to be false positives, according to a poster presentation on September 7 at the American Society of Clinical Oncology (ASCO) 2013 Breast Cancer Symposium (BCS).
Whole-body MRI may predict heart attack, stroke in diabetics
September 10, 2013 -- Whole-body MRI can detect vascular changes in patients with diabetes that can signal an increased risk of heart attack and stroke, according to a new study by German researchers published online September 10 in Radiology.
ASCO BCS: Simplified protocol improves breast MRI screening
September 9, 2013 -- SAN FRANCISCO - A streamlined protocol for breast MRI could make the modality a viable option for breast cancer screening by cutting image acquisition and reading time to just three minutes, according to a presentation on September 7 at the American Society of Clinical Oncology (ASCO) 2013 Breast Cancer Symposium (BCS).
Breast MRI boosts survival in high-risk women -- but at a price
August 30, 2013 -- Screening MRI may improve survival rates for women with family risk factors for breast cancer. But the technology is expensive, especially for younger women, so finding screening alternatives may be beneficial, according to a new study published online in the Journal of the National Cancer Institute.
PET/MRI helps with pulmonary nodule detection -- to a point
August 30, 2013 -- Simultaneous PET/MRI performs better than PET and MRI performed separately for the detection of FDG-avid pulmonary nodules and lesions at least 0.5 cm in size. However, it has problems with non-FDG-avid nodules and smaller lesions, researchers report in the September issue of Radiology.
