Is gadolinium deposition disease really a disease?
November 9, 2018 -- Is gadolinium deposition disease really a disease? Italian researchers aren't so sure after they studied patients who received gadolinium-based contrast agents for MRI scans. They reported their findings in a study published online October 30 in Investigative Radiology.  Discuss
MRI reveals mechanics of beatboxing
November 8, 2018 -- Have you ever wondered how performers can so fluidly make those syncopated beatboxing sounds? Researchers have shed some light on the mystery by using real-time MRI to show how motions of the mouth and tongue create different beatboxing sounds and styles.  Discuss
Heart valve-tracking algorithm boosts viability of 4D MRI
November 2, 2018 -- An automated heart valve-tracking algorithm halved the amount of time and variability involved in blood-flow quantification with 4D MRI, according to an article published online October 30 in Radiology. The improved efficiency may help convince clinicians that cardiac 4D MRI is useful for assessing valvular heart disease.  Discuss
2nd MRI center reports problems with Apple devices
November 1, 2018 -- A second imaging facility is reporting problems with Apple devices that appear to be related to the operation of the center's MRI scanner. Nearly 10 late-model Apple iPhones and Watches were permanently disabled at a Delaware center after it ramped down its MRI magnet.  Discuss
Did MRI helium leak take out hospital's iPhones?
October 31, 2018 -- Social media websites are buzzing with speculation that newer Apple iPhones are susceptible to helium leakage from MRI scanners, based on a recent incident at a hospital near Chicago in which more than three dozen Apple devices stopped working after a scanner installation.  Discuss
Canadian group tackles MRI waits through scheduling
October 31, 2018 -- Wait times for MRI scans have been a troublesome issue in Canada. But in Ontario, researchers have developed a method that could double the number of patients who receive MRI scans within targeted wait times by using computer technology to give higher priority to patients the longer they have been waiting.  Discuss
MRI shows how extended space travel affects the brain
October 29, 2018 -- Recovering from weightlessness might be the least of the problems that astronauts face when they return home to Earth. MRI scans revealed a loss of gray-matter volume in the brain soon after touchdown and prolonged changes in circulation of cerebrospinal fluid some seven months later, according to a study published in the October 25 issue of the New England Journal of Medicine.  Discuss
MRI could play role in curing digestive disorders
October 26, 2018 -- Relief may finally be near for people who experience significant abdominal pain and discomfort. Researchers at Purdue University are developing a way to use MRI to track the efficacy of electric stimulation of the vagus nerve to alleviate stomach dysfunction, according to a paper published in the October issue of Neurogastroenterology and Motility.  Discuss
Can whole-body MRI be used in oncologic staging?
October 23, 2018 -- Offering similar performance to PET/CT but without requiring radiation dose, multiparametric whole-body MRI could feasibly be used for staging metastatic lesions and evaluating treatment response in a variety of cancers, according to a study published in the November issue of Academic Radiology.  Discuss
Gadolinium-enhanced MRI with PET best for prostate cancer
October 22, 2018 -- Which MR imaging sequence used with whole-body fluorocholine-PET/MRI is most proficient at detecting metastases and staging patients with prostate cancer? Canadian researchers put four sequences through their paces in a study published online October 17 in the American Journal of Roentgenology.  Discuss
