CSF may be gadolinium's route to the brain
July 20, 2018 -- A study published in the August issue of Radiology offers further evidence of a mechanism for gadolinium deposition in the brain after the administration of MRI contrast. Researchers detected gadolinium accumulation in cerebrospinal fluid (CSF) -- even in patients with an undamaged blood-brain barrier and normal renal function.  Discuss
FDDNP-PET shows brain injury effects in military personnel
July 19, 2018 -- Researchers have found that changes in PET scans of military personnel with mild traumatic brain injury are similar to those seen in retired football players with suspected chronic traumatic encephalopathy, according to a study published online July 17 in the Journal of Alzheimer's Disease.  Discuss
Cardiac MRI offers prognosis for hard-to-find infarctions
July 18, 2018 -- Cardiac MRI can play a critical role in helping to determine which patients suspected of having stable coronary artery disease could have an unrecognized myocardial infarction and an increased risk of an adverse cardiac event, according to a study published online recently in PLOS One.  Discuss
PET could make synaptic density an Alzheimer's biomarker
July 17, 2018 -- Researchers from Yale University are reporting promising results with a PET tracer designed to assess synaptic density in patients with Alzheimer's disease. The hope is that the approach could become an in vivo biomarker for dementia and help in therapy development, according to a paper published online July 16 in JAMA Neurology.  Discuss
MRI links iron in the brain to multiple sclerosis
July 17, 2018 -- Lower levels of iron in the thalamus as seen on MRI scans of people with multiple sclerosis are a strong indication that the disease will progress and lead to greater disability, according to a study published online July 17 in Radiology.  Discuss
Women's menstrual phase may increase radiation risk
July 13, 2018 -- Hormonal changes caused by a woman's menstrual cycle may put them at higher risk of developing cancer from exposure to medical radiation, according to a letter published July 10 in Radiology. Providers may want to consider menstrual phase when deciding when to perform studies -- particularly nuclear medicine exams -- in younger women, the researchers recommended.  Discuss
C-11-based PET tracer could benefit arthritis patients
July 9, 2018 -- Carbon-11 (C-11) PET that targets translocator protein expression in the joint lining tissue of the knee may be a better way to determine the extent of rheumatoid arthritis, according to a study published in the July issue of the Journal of Nuclear Medicine.  Discuss
Time-of-flight PET can reduce radiation dose in pediatrics
July 9, 2018 -- By adding a time-of-flight technique to pediatric PET scans, clinicians can adjust radiation dose levels by as much as 50% with no discernible loss of diagnostic image quality, according to a study presented at the Society of Nuclear Medicine and Molecular Imaging annual meeting in Philadelphia.  Discuss
MRI links inflammation to cognitive decline
July 3, 2018 -- Using MRI, researchers have found that chronic inflammation measured by a biomarker in the blood of middle- to late-age adults could be linked to visible white-matter damage in the brain and related poor cognition and dementia, according to a study in the August issue of Neurobiology of Aging.  Discuss
MRI brain scans show benefits of prenatal folic acid
July 3, 2018 -- MRI scans show that adolescents whose mothers received food enriched with folic acid while they were pregnant have enhanced brain development and a reduced risk of psychosis and other mental illnesses as they progress toward adulthood, according to a study published online July 3 in JAMA Psychiatry.  Discuss
