Portable MRI- bringing MRI to bedside in stroke patients

"We started this research several years ago because obtaining accessible, meaningful brain imaging for patients has been a major worldwide health care gap for decades," Sheth said. "The whole thing works because we are using low-field magnets to acquire brain images after a stroke."

"High-field magnets are the cornerstone of commercial MRIs. The portable, low-field MRI could be used at hospitals that currently have a high-field MRI and in any other setting where an MRI is currently not available."

He added that the portable MRI devices will also decrease need for a special power supply, cooling requirements, cost and other barriers that currently limit easy patient access

In addition, the low-field, bedside MRI scanner did not interfere with other equipment, and metals did not need to be removed from the room. No significant adverse events were reported.

"There's a lot of work to do, however, we've cracked the door open for bringing this technology to any setting, anywhere. In rural settings, urban advanced hospitals and in remote villages in areas of the world where it's hard to get an MRI - not anymore," Sheth said.

Sheth said next steps include scanning more patients, improving image quality, using the devices in multiple settings and using machine learning to extract as much meaningful information as possible.
