"The higher the magnetic field, the more difficult it is to really grab the potential promised by these higher-field MR scanners to see finer details in the human brain," he said. "You need all this peripheral equipment, which needs to be on steroids to meet those promises.”
NexGen 7T MR systems have ten times higher resolution than standard 7T scanners and over 50 times more than 3T ones.
In addition to its refined gradients, NexGen 7T has a 128-channel receiver system that replaces the standard 32 channels for higher signal-to-noise ratio, and higher parallel imaging acceleration for faster data acquisition to encode large image matrices. It also has new pulse sequences of precisely timed gradient pulses to rapidly achieve ultrahigh resolution.

The scanner was a rebuilt version of a 7T system installed at UC Berkeley in 2020, and the project was backed by $22 million in funding from UC Berkeley's chancellor's office and the Weill Neurohub, and Brain Research through Advancing Innovative Neurotechnologies (BRAIN). Other NexGen 7T brain scanners must be custom built from regular 7T scanners but should cost substantially less than the first.
“We will soon be able to understand the human brain organization better, which will give us a new view into disease processes and ultimately allow us to test new therapies,” said Feinberg.
The findings were published in
Nature Methods.
