Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Novel protein biomarker can help improve dementia risk prediction

Identifying those who are at risk of dementia, a type of neurodegenerative disease, is crucial for early treatment and development of new therapies, a new study suggests.

Medical imaging rates continue to increase despite broad campaign to reduce their use

Despite a broad campaign among physician groups to reduce the amount of imaging in medicine, the rates of use of CT, MRI and other scans have continued to increase in both the U.S. and Ontario, Canada, according to a new study of more than 135 million imaging exams conducted by researchers at UC Davis, UC San Francisco and Kaiser Permanente.

Study proves that auditory pathways are more specialized in speech than previously assumed

Neuroscientists at TU Dresden were able to prove that speech recognition in humans begins in the sensory pathways from the ear to the cerebral cortex and not, as previously assumed, exclusively in the cerebral cortex itself.

Loss of cells in the brain found to be associated with stuttering

Researchers believe that stuttering - a potentially lifelong and debilitating speech disorder - stems from problems with the circuits in the brain that control speech, but precisely how and where these problems occur is unknown.

Tighter blood pressure control could improve brain health finds study

Tighter blood pressure control is standard practice in hypertension therapy. Researchers have found that in addition to the benefits this provides to the heart and the vascular system, it also helps lower the risk of cognitive decline and dementia associated with age

Greater blood pressure control associated with fewer adverse changes in the brain

For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment, according to new research published in the Journal of the American Medical Association.

New bimodal contrast agent suits both MRI and photoacoustic imaging

Magnetic resonance imaging visualizes internal body structures, often with the help of contrast agents to enhance sensitivity.

Early neuroimaging essential for Zika-exposed infants

Seventy-one of 110 Brazilian infants at the highest risk for experiencing problems due to exposure to the Zika virus in the womb experienced a wide spectrum of brain abnormalities, including calcifications and malformations in cortical development, according to a study published July 31, 2019 in JAMA Network Open.

Blood pressure drug appears to be helpful for people with Alzheimer's disease

Seeking new treatments to slow the progression of Alzheimer's disease, researchers found the blood pressure drug nilvadipine increased blood flow to the brain's memory and learning center among people with Alzheimer's disease without affecting other parts of the brain, according to new research in the American Heart Association's journal Hypertension.

Genetic study on liver iron content may pave way for better treatment

High levels of iron in the liver are linked to a number of serious health conditions including cancer, diabetes, high blood pressure and cardiovascular as well as liver disease. But measuring liver iron is difficult and until recently could only be done through an invasive biopsy.
