Multiparametric MRI can help avoid renal mass biopsies
January 10, 2018 -- Researchers at the University of Texas Southwestern have discovered that radiologists using multiparametric MRI have an 80% chance of detecting clear cell carcinoma in the kidneys without the need for a confirming biopsy. In addition, the technique was successful among radiologists with varying levels of expertise.  Discuss
MRI links function of brain networks to IQ
January 5, 2018 -- A person's intelligence could soon be confirmed with an MRI scan to assess how well connected and functional his or her neurological networks are, according to a study published in the January issue of Neuron.  Discuss
NEJM: No long-term effects on cardiac devices with MRI
January 2, 2018 -- There's good news for patients with cardiac devices who are about to undergo an MRI scan. Researchers found no long-term clinically significant adverse events with the devices in a study of more than 1,000 scans, according to results published in the December 28 issue of the New England Journal of Medicine.  Discuss
Gadolinium in fetuses almost entirely cleared via placenta
January 2, 2018 -- Only trace amounts of the gadolinium administered to pregnant monkeys cross the placenta and enter the fetuses, and most of this gadolinium quickly returns back to the mother's bloodstream for excretion, according to research published in the January issue of Radiology.  Discuss
FDA issues directive on GBCA labeling, safety research
December 19, 2017 -- The U.S. Food and Drug Administration (FDA) on Tuesday issued a directive requiring that manufacturers of gadolinium-based contrast agents (GBCAs) add a new warning to their product labeling that notifies healthcare providers that patients could retain gadolinium long after an MRI scan.  Discuss
X-ray fluorescence detects retained gadolinium in bone
December 19, 2017 -- As the safety of gadolinium MRI contrast is hotly debated, one of the challenges has been detecting gadolinium deposition in living patients. Canadian researchers may have found a solution to the dilemma with an x-ray fluorescence system that can noninvasively detect trace elements of gadolinium in exposed individuals.  Discuss
MRI confirms prostate cancer with lower dose of GBCA
December 14, 2017 -- MRI scans with a reduced dose of a gadolinium-based contrast agent (GBCA) can be more effective than scans with a standard dose in differentiating between malignant and benign lesions in prostate cancer patients, according to a study presented recently at RSNA 2017.  Discuss
fMRI, PET could help foresee epileptic seizure issues
December 12, 2017 -- Researchers have developed a method to integrate functional MR (fMRI) and PET images to identify epilepsy patients who are at high risk of continued seizures before the patients undergo potentially unsuccessful surgery, according to a study published online December 5 in Frontiers in Neuroscience.  Discuss
PET/MRI outclasses MRI alone for pelvic cancer recurrence
December 11, 2017 -- PET/MRI can better detect and classify local lesions and distant metastases in women suspected of having recurrent pelvic cancer than MRI alone, according to a study presented at the recent RSNA 2017 annual meeting.  Discuss
SABCS: Biannual breast MRI best for young women at high risk
December 11, 2017 -- For young women with a high genetic risk of breast cancer, twice-yearly MRI exams are more effective for detecting early disease than an annual mammogram, according to new research presented at the 2017 San Antonio Breast Cancer Symposium (SABCS).  Discuss
