FDA finds no health effects from gadolinium retention
May 23, 2017 -- There is no evidence that gadolinium remaining in the body after MRI contrast administration has any negative health effects, according to a review published on May 22 by the U.S. Food and Drug Administration (FDA). The announcement is unlikely to settle the debate over gadolinium contrast safety, however.
MRI shows true value in invasive placenta
May 22, 2017 -- Further evidence of MRI's ability to confirm suspected placental anomalies or to assist in cases of equivocal ultrasound findings has come from Saudi Arabia. A study of pregnant women found that noncontrast MRI is a sensitive diagnostic test for detecting invasive placenta.
Short breast MRI protocol works for cancer detection
May 19, 2017 -- A shortened protocol for breast MRI is just as effective in finding cancer as a full protocol, and it can cut the time a patient is in the magnet by almost 90%, according to a study published online May 11 in Academic Radiology.
MRI training improves performance, patient satisfaction
May 17, 2017 -- By training MRI technologists in advanced communication skills, outpatient imaging centers can improve equipment utilization, hourly scan rates, and patient satisfaction, all while avoiding the potential loss of business to competing facilities.
Gadolinium dosing calculator can guide MRI contrast use
May 15, 2017 -- Given the ongoing concern over the safety of gadolinium-based contrast agents (GBCAs), researchers have developed a resource for MRI technologists and radiologists that calculates accurate and appropriate GBCA doses for patients to avoid dosing errors.
Elekta debuts MR-linac radiation therapy system at ESTRO
May 8, 2017 -- Radiation oncology vendor Elekta is using this week's annual meeting of the European Society for Radiotherapy and Oncology (ESTRO) to launch Elekta Unity, the company's MRI-guided radiation therapy system.
MRI detects cause of vision problems in astronauts
May 5, 2017 -- MRI scans of astronauts who spent time at the International Space Station confirm that increased orbital and ventricular cerebrospinal fluids cause vision problems that worsen with extended time in space and linger after the travelers have returned to Earth.
Weight loss can help prevent knee cartilage degeneration
May 2, 2017 -- While there's little doubt that being overweight can be detrimental to the body, a new study published online May 2 in Radiology adds to the evidence. MRI scans showed significantly less knee cartilage deterioration in obese people who lost more than 10% of their weight over four years.
MRI scans of 'brain age' could predict poor health
April 25, 2017 -- Researchers combined MRI scans with machine-learning algorithms to develop a "brain age" score that could provide insights into which patients are at risk for poor health and may die at an early age, according to a study published online April 25 in Molecular Psychiatry.
5-minute shoulder MRI could ease patient anxiety
April 19, 2017 -- By taking advantage of parallel imaging on the latest generation of 1.5- and 3-tesla scanners, researchers have devised a quick five-minute shoulder MRI protocol that still produces diagnostic-quality images, according to a study in the April issue of the American Journal of Roentgenology.
