MRI

Image: Using an MRI technique that is sensitive to certain byproducts of cell metabolism, including levels of glucose and acidity, University of Iowa researchers discovered previously unrecognized differences in the brains of patients with bipolar disorder. The T1rho MRI scans showed brain regions of elevated signal in the 15 participants with bipolar disorder compared to the 25 participants who did not have bipolar disorder. The primary regions of difference are the cerebral white matter (yellow) and the cerebellum (red) (Photo courtesy of the University of Iowa).

Quantitative, High-Resolution T1 Rho MRI Mapping Scan Reveals Brain Differences in Bipolar Disorder

Using a different sort of magnetic resonance imaging technology, researchers have discovered previously unrecognized differences in the brains of patients with bipolar disorder. In particular, the study revealed differences in the white matter of patients’ brains and in the cerebellum, an area of the brain not previously linked with the disorder.   More...

New Hyperpolarizer Enables Users to Double Polarization Levels for MR Imaging of Lungs

New technology has been devised to generate hyperpolarized inert xenon gas, which is used in conjunction with standard magnetic resonance imaging to create high resolution three-dimensional images of the human lung. This technique is a novel way to track extremely small changes in lung structure and lung function, and is used in basic and clinical research to study lung physiology and to monitor the efficacy of new drugs.   More...

Imaging Test Designed for Autism Spectrum Disorder

 Scientists have developed a brain-imaging technique that may be able to identify children with autism spectrum disorder in just two minutes. Typically, diagnosis—an unquantifiable process based on clinical judgment—is time-consuming and tiresome on children and their families. That may change with this new diagnostic test. More...

Quantitative Diffusion Tensor MRI Technology Diagnoses Head Injuries Not Seen on Standard MRI, CT Scans

An imaging center in the US state of Louisiana is now using quantitative diffusion tensor imaging, a new magnetic resonance imaging technology, to detect brain damage that cannot be seen on standard MRI or computed tomography scans.   More...
