Minimize gadolinium dose in hereditary tumor patients

By Rebekah Moan

Gadolinium accumulation occurs in most patients undergoing contrast MRI screening after more than five MRI scans, so Belgian researchers have advocated a screening protocol for individuals with hereditary tumor syndromes that minimizes the gadolinium dose.

PET aids in new Alzheimer's discovery

By Wayne Forrest

With the help of PET imaging, researchers at the University of Cambridge believe they have confirmed the process by which tau proteins spread in the brain to advance Alzheimer's disease, according to a study published on 5 January in the journal Brain.

Florbetapir shows promise in preclinical Alzheimer's study

By Wayne Forrest

A preclinical study from Belgium has shown promising results with the PET tracer florbetapir for targeting amyloid plaque and tau tangles in the brain and potentially evaluating the efficacy of certain Alzheimer's treatments. Findings were published in the December issue of the Journal of Nuclear Medicine.

MRI technique may help diagnose migraine headaches

By Erik L. Ridley

While painful and often debilitating for patients, migraines can also be difficult to diagnose and differentiate from other types of headaches. An MRI technique may help alleviate that diagnostic challenge, according to research presented on November 28 at the RSNA 2017 meeting in Chicago.

Functional MRI sheds new light on sound and touch

By Michael Asghar

Researchers in the U.S. and the Netherlands have observed auditory responses in the human somatosensory cortex, a region of the brain usually dedicated to processing touch. They measured functional MRI signal changes following a frequency discrimination task.

MRI could be 'game changer' for cardiac arrest survivors

By Wayne Forrest

By taking MRI measurements of the brain's functional network connectivity within two weeks after a patient experiences cardiac arrest, clinicians may be better able to predict their clinical outcomes, according to a study published online on October 18 in Radiology.

PET, EEG show treatment effectiveness in comatose patient

By Wayne Forrest

Imagine being able to restore consciousness to a patient who has been comatose for 15 years. French researchers succeeded in accomplishing that goal, with the help of PET and electroencephalography (EEG) to confirm the efficacy of vagus nerve stimulation, according to a study published online in Current Biology.

fMRI links brain disruptions to Parkinson's hallucinations

By Wayne Forrest

Researchers from VU University Medical Center in Amsterdam used functional MRI (fMRI) to visualize disruptions in several areas of the brain associated with attention and visual processing in people with Parkinson's disease. The findings could explain visual hallucinations in these patients, according to a paper published online on September 27 in Radiology.

MRI correlates brain changes to cognitive decline

By Geoffrey Potjewyd

Researchers from multiple groups in the U.K., headed up at St George's University of London, have developed a single score MR imaging methodology for correlating cerebral small vessel disease damage to cognitive decline.

PET with AV-1451 times tau deposits with Alzheimer's onset

By Wayne Forrest

Using PET with the novel radiotracer fluorine-18-AV-1451 that binds to tau deposits, Swedish researchers have linked certain regions of the brain with the early or late onset of Alzheimer's disease and its symptoms, according to a study published in the September issue of Brain.
