fMRI test emotional faces: Schizophrenia clue

Date: Jan 7, 2019

Author: David Bradley

Functional magnetic resonance imaging research published in The American Journal of Psychiatry demonstrates that people can use their brains differently when mimicking an emotional facial expression. This task can reflect how well a person might interact socially. Moreover, by also including people with schizophrenia, the research has found that there is no categorical difference in social brain function in people with this condition and those without it.

Journal Highlight: Magnetic resonance imaging with cochlear implants and auditory brainstem implants: Are we truly practicing MRI safety?

Date: Dec 17, 2018

Author: spectroscopyNOW

The safety of patients with cochlear implants and auditory brainstem implants undergoing 1.5-T MRI has been discussed by examining retrospective cases from 2006-2018, to better understand MRI‐related adverse events and prevent them in the future.

Journal Highlight: A simplified framework to optimize MRI contrast preparation

Date: Nov 19, 2018

Author: spectroscopyNOW

A rigorous optimal control framework has been designed for the design of preparation schemes that optimize MRI contrast based on relaxation time differences.

Journal Highlight: In vivo diffusion MRI detects early spinal cord axonal pathology in a mouse model of ALS

Date: Nov 8, 2018

Author:

Diffusion magnetic resonance imaging (MRI) exhibits contrast that identifies macro‐ and microstructural changes in neurodegenerative diseases. Previous studies have shown that MR diffusion tensor imaging (DTI) can observe changes in spinal cord white matter in animals and humans affected with symptomatic amyotrophic lateral sclerosis (ALS).

Electrifying your gut: MRI monitors digestive aid

Date: Nov 1, 2018

Author: David Bradley

Electrical stimulation could solve many gastrointestinal problems for millions of people around the world. Now, magnetic resonance imaging (MRI) studies have taken a closer look at how such therapy affects the stomach when the vagus nerve is stimulated.

Journal Highlight: Noncontrast breast MRI during pregnancy using diffusion tensor imaging: A feasibility study

Date: Oct 22, 2018

Author: spectroscopyNOW

The feasibility and clinical utility of noncontrast breast MRI using diffusion tensor imaging has been investigated in the diagnostic workup of pregnancy‐associated breast cancer, revealing that the technique is feasible and well‐tolerated during pregnancy.

Bleeding brains: MRI finds what matters

Date: Oct 1, 2018

Author: David Bradley

A research team that includes University of California Irvine project scientist Rachita Sumbria, PhD, and UCI neurologist Mark Fisher have obtained evidence for the first time that shows that blood deposits in the brain may not necessarily be due to a tear in a blood vessel.

Journal Highlight: 4‐year outcomes from an MP‐MRI based active surveillance programme – PSA dynamics and serial MRI scans allow omission of protocol biopsies

Date: Sep 24, 2018

Author: spectroscopyNOW

A study of the outcomes from a multi‐parametric MRI-based active surveillance programme that did not perform protocol biopsies after the first confirmatory biopsy concluded that men with low-risk Gleason 3+3 cancer can forgo protocol biopsies in favour of MRI and PSA monitoring with selective re‐biopsy.

Obesity is in your head: MRI and weight gain clues

Date: Sep 1, 2018

Author: David Bradley

An examination of magnetic resonance imaging (MRI) and cognitive test data from 1,200 individuals, supplied as part of the Human Connectome Project shows that when it comes to weight gain, the problem may be mostly in our heads and in our genes.

Journal Highlight: Applications of PET‐MRI in musculoskeletal disease

Date: Aug 20, 2018

Author: spectroscopyNOW

Emerging applications of PET‐MRI in musculoskeletal disease have been reviewed, including clinical applications of malignant musculoskeletal disease, new opportunities involving nononcologic musculoskeletal disease and relevant technical considerations and challenges.
