Using MRI and Machine Learning to Predict Cognitive Abilities in Infants
Magnetic Resonance Imaging (MRI) can now be used in conjunction with machine learning to predict cognitive development in infants, according to a studyrecently published inNeuroImage.White matter is intrinsic to developing brain activity, and the white matter connectome at birth can be used as a neuroimaging biomarker to calculate cognitive development. The group of researchers led by Jessica B. Girault, PhD, from the Carolina Institute for Developmental Disabilities at the University of North Carolina Chapel Hill are searching for imaging biomarkers like white matter to determine risks for neuropsychiatric conditions,...

Why We Need End-to-End Encryption on PACS
Malware is being used to manipulate CT and MRI scans to create detrimental misdiagnoses, according to researchers from theBen-Gurion University Cyber Security Research Center inBeersheba,Israel. In lieu of the data breaches and cyber attacks that plagued hospitals in 2018, the researchers set out to learn how attackers use deep learning to implant fake cancerous nodules or remove real ones in medical scans without expert radiologists having the slightest idea. In a blind study, radiologists read a batch of real CT scans, 70 percent of which had been doctored by malware. For all of the scans with fake cancerous nodules, the...

New MRI-Based Calcium Sensor Helps Us Better Understand Neuron Activity
Researchers have created a way to use magnetic resonance imaging (MRI) to measure calcium activity in order to analyze signal processing in neuron behavior in living animals, according to a study recently published inNature Communications.Calcium analysis can demonstrate critical neuron activity. However, current technology is limited, and can only enter the first few millimeters of the brain ’s surface. Researchers at the Massachusetts Institute of Technology have developed an MRI-based intracellular calcium sensor that can penetrate cell membranes. The technique identifies magnetic interactions with a manganese-based c...

When Should You Hold Your Breath During an Abdominal MRI?
Holding one ’s breath at the end of the exhale instead of at the end of the inhale during magnetic resonance imaging (MRI) scans of the liver can reduce respiratory motion artifacts, according to a studyrecently published in theAmerican Journal of Roentgenology.For the study, researchers from Stanford University collected both unenhanced and contrast-enhanced images of end-inspiration and end-expiration breath-holding techniques from 47 participants undergoing axial T1-weighted liver MRI. Three radiologists evaluated the quality of the images based on a rubric of one point for motion artifact-obscured to five points for...

Funding for AI-Based Medical Imaging Systems Doubled in 2018
Companies that develop AI-driven medical imaging systems collectively received nearly $580 million in funding in 2018, according to a recent reportfrom healthcare research firm Signify Research.AI has become a popular focus in medical imaging innovation, with over 120 start-ups adamantly working to create advancements in the field. Since 2014, investors have contributed more than $1.2 billion to these companies, and funding levels are double what was reported in 2017.According to the report, the number of early-stage (i.e. Angel Seed and Series A) investments has dropped since 2015-2016 after the “peak of new market ...

Kansas State University Welcomes New MRI for Large Animals
A new magnetic resonance imaging (MRI) machine at Kansas State University, which took three years to install, is finally ready to scan neurological injuries in large animals.According to KSNT, this is the Midwest ’s first MRI of its kind. Its fast imaging speed reduces the amount of time animals have to spend in the machine. According to David Biller, professor of radiology at Kansas State’s College of Veterinary Medicine, the MRI offers several advantages that conventional scanners lack. “We will be a ble to image smaller structures more rapidly,” he said. “With the greater detail or ability to image smaller s...

New $2,000 Ultrasound Can Increase Imaging Access Around the Globe
The Butterfly iQ, a small, handheld ultrasound scanner that connects to your smartphone, is now being used by physicians to conduct obstetric, lung, and cardiac imaging procedures.There are several aspects that set the Butterfly iQ apart from traditional scanners. Instead of using piezo crystals, the material commonly used to create ultrasonic waves, the device incorporates a single silicon chip that generates ultrasound waves that flow through the body. This technology significantly reduces the price and can be purchased for $2,000.The silicon chip was invented by Jonathan Rothberg, PhD, who has founded multiple medic...
