Facebook and NYU fastMRI project: largest-ever open source dataset using AI for 10X faster MRI’s
2018 04 Dec
In what is the largest public release of raw data to this day, the NYU School of Medicine’s Department of Radiology and Facebook join forces on a collaborative research project that will share open source tools to propel the development of AI systems that may produce 10 times faster MRI scans. More than 1.5 million anonymised MR images of the knee,... Read more
#RSNA18: MRI finds depression and anxiety brain pattern
2018 27 Nov
In a study presented at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, researchers have uncovered a common pattern of structural similarities and differences in the brains of people suffering from depression and social anxiety using MRI. The study compared major depressive disorder (MDD) and social anxiety... Read more
#RSNA18: AI may help reduce MRI gadolinium dose
2018 27 Nov
In a study presented at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, researchers using artificial intelligence have developed a deep learning algorithm that may lead to the reduction of the gadolinium dose used in contrast material for MRI exams. “There is concrete evidence that gadolinium deposits in the brain...

#RSNA18: MRI more accurate to predict Alzheimer’s disease
2018 20 Nov
A new study that will be presented next week during the annual meeting of the Radiological Society of North America (RSNA) shows MRI brain scans are better at predicting the development of Alzheimer’s disease in patients compared to clinical tests commonly used today. Until now, the standardized questionnaires and tests to measure cognition and... Read more
Key imaging and clinical features of paediatric head trauma
2018 24 Oct
Paediatric head trauma is an important cause of morbidity and mortality in children and may be seen in the setting of accidental or abusive injuries. Many of the patterns of head injury are similar to adults, but it is worth noting that the imaging manifestations of head injury in children are more complex due to the developing brain and calvarium,...

MRI technique helps detect multiple sclerosis disability risk
2018 25 Jul
Researchers have tested a new MRI technique, called quantitative susceptibility mapping (QSM), to track iron levels in the brains of multiple sclerosis patients. They found that brain iron levels can help identify those at a higher risk for developing physical disability, according to a new study published in the journal Radiology. Multiple... Read more
New MRI technique for detecting Alzheimer’s disease
2018 18 Jul
Researchers in Spain have developed a new contrast agent for magnetic resonance imaging (MRI) based on functionalised magnetic nanoparticles that could work as a biomarker for early diagnosis of Alzheimer’s disease. Their work could pave the way for new studies that develop methods of early and noninvasive diagnosis of this neurodegenerative disease. ... Read more
Radiomics in magnetic resonance imaging: the need for standardisation
2018 06 Jun
Radiomics is a hot topic in radiology. A steadily increasing number of researchers across the globe is engaging in radiomics and applying it to a large number of imaging data. “Radiomics” means the extraction of a large number of quantitative imaging features from routinely acquired imaging data (e.g, x-ray, ultrasound, CT, MRI, PET) in order to...

MRI: rapid determination of implant safety status
2018 02 May
Safety screening is an essential prerequisite to magnetic resonance imaging (MRI). Radiologist approval is often required to determine whether MRI can proceed safely in patients with medical and cosmetic devices or embedded foreign bodies. Although many sources of safety information are available online, MRI may be delayed or cancelled, especially... Read more
