Hyperpolarized nuclear MR: more precise diagnoses and personalized therapies

17/05/2022

Hyperpolarized nuclear magnetic resonance enables major medical advances in molecular diagnostics, for example for cardiovascular diseases or cancer therapy. Within the framework of the EU collaborative project "MetaboliQs", seven partners developed a microscopy method which enables the analysis of metabolic processes at the single cell level by means of diamond-based hyperpolarization.

Lung cancer treatment: model to predict patients with poor outcomes

04/05/2022

Moffitt Cancer Center researchers are working to improve the ability to identify patients who are at a higher risk of poor survival through radiomics, an area of science that uses imaging, such as CT scans and MRIs, to uncover tumoral patterns and characteristics that may not be easy to spot by the naked eye.

Broader perspective: how Mixed and Virtual Reality transform surgery

01/04/2021

For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.

Surgical planning with immersive mixed reality

01/04/2021

The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.

Gamification: how penguins help children overcome their MRI fear

23/04/2019

It's noisy, tight and scary - that's how children feel about a magnetic resonance imaging (MRI) machine. Because they are scared, they are often too fidgety and anxious during the procedure, causing the images to blur or the scan to be stopped. Researchers have now developed a VR app called Pingunauten Trainer that’s designed to gently prepare the little patients for MRI scans.

Brain mapping: preoperative planning with functional MRI

01/04/2019

A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.

Functional imaging: a look at the command center

01.04.2019

All information from our body and the environment converges in our brain and is transformed into reactions in milliseconds. It is essential for medicine and research to know what our switching centre looks like. Functional methods are used to observe it more closely during work.

WAKE-UP study a wake-up call for acute stroke care

08/08/2018

Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.
