Contrast deposition: MRI agents

Date: Jul 1, 2017

Author: David Bradley

New research published in the journal Radiology suggests that traces of the contrast agent gadolinium can be found in brain tissues many years after administration during magnetic resonance imaging (MRI). Intracranial deposition seems to occur even in patients with an intact blood-brain barrier.

Meta MRI: Scan booster

Date: Jun 1, 2017

Author: David Bradley

A meta material can boost the local sensitivity of magnetic resonance imaging (MRI), according to work by researchers from the Netherlands and Russia who have demonstrated the system with in vivo scanning of people for the first time.

Accentuating the positive: fMRI investigation

Date: May 1, 2017

Author: David Bradley

Functional MRI has been used to measure the activity in different regions of the brain of subjects shown disturbing images of violence - war and accidents - in an investigation aimed at understanding how poor sleep in anxiety and depression might make it harder for people to see the world positively.

Journal Highlight: Pulmonary MRI of neonates in the intensive care unit using 3D ultrashort echo time and a small footprint MRI system

Date: Mar 27, 2017

Author: spectroscopyNOW

The feasibility of pulmonary MRI of neonatal lung structures in free breathing subjects enabled by combining two novel technologies has been studied using a 3D radial ultrashort echo time pulse sequence and a unique, small-footprint 1.5T MRI scanner design.

New light on MRI: Contrast boost

Date: Mar 1, 2017

Author: David Bradley

A new technology platform can effectively tune the magnetic resonance imaging (MRI) signals in a scan switch on a contrast-boosting lamp on diseased tissue. Details are published in the journal Nature Materials suggesting that the approach might overcome some of the limitations of MRI contrast agents.
