Treatment and study plan

0.7 T MRI

Device

Our scanner is based on a unique high-temperature superconducting magnet that is highly compact, weighs only 400 kg, and requires no cryogens. Its innovative design allows the subject to sit normally with sightlines to the room and produces low acoustic noise during scanning.

Primary outcomes

Image Quality

Time frame: Day 1

The study will quantitatively compare images obtained at 0.7 Tesla (obtained with new methods and instrumentation) with images obtained with conventional MRI. The metrics to be assessed include: spatial resolution, signal-to-noise ratio, signal-to-artifact ratio, contrast-to-noise ratio, and geometric distortion.
