How is the study designed?

Design Details

  • Primary Purpose: Basic Science
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 0.7 T MRI
Device: 0.7 T MRI
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
