Prenatal MRI study suggests autism differences may begin in the womb
A small Boston Children’s Hospital study led by Assistant Professor Emi Takahashi and postdoc Alpen Ortug showed increased volume of the insular lobe as a potential strong prenatal MRI biomarker that could predict the emergence of ASD later in life. It revealed significant differences in brain structures at 25 weeks’ gestation between children who were…

AI speeds MRI scans
Facebook and NYU’s fastMRI project, led by Larry Zitnick, uses AI in an attempt to make MRI imaging 10 times faster. Neural networks will be trained to fill in missing or degraded parts of scans, turning them from low resolution into high. The goal is to significantly reduce the time patients must lie motionless inside an…

Ultra-low-field, portable MRI
Los Alamos National Laboratory‘s Michelle Espy is developing an ultra-low-field, lightweight MRI system for use on the battlefield and in poor countries. The device will be simple to transport, set up, and use in non-traditional settings. Conventional MRI machines use large magnetic fields that align protons in water molecules. Magnetic resonance signals are detected and turned into images. Highly detailed…

High speed MRI analyzes vocal movement
Aaron Johnson of The Beckman Institute has developed an MRI technique that can view dynamic images of vocal movement at 100 frames per second. This speed is far more advanced than any other MRI technique. The method is especially useful in studying how rapidly the tongue moves, along with other muscles in the head and neck, during…
