This study is being done to assess new Magnetic Resonance Imaging (MRI) technologies such as new hardware or software designed to improve MRI examinations of the brain, spine, and head & neck regions. Software and hardware are always being improved, new machines replace old machines, software is updated and improved as well as devices used to produce better MRI images.

Condition Intervention
Nervous System Diseases
Procedure: MRI

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic

Further study details as provided by University of Michigan:

Primary Outcome Measures:
  • Improvement in quality of MRI studies in Neuroradiology [ Time Frame: 1 year ] [ Designated as safety issue: No ]

    Specific Measurement Are:

    1. Scan speed - is the new method as fast or faster than regular method(s)
    2. Signal to noise - Subjectively, or quantitatively do we get the same, better, or new contrast compared to the regular methods(s).
    3. Image contrast - Subjectively, or quantitatively do we get the same or better resolution compared to the regular method(s).
    4. Spatial resolution - Subjectively, or quantitatively do we get the same or better resolution compared to the regular method(s).
    5. Artifact - Subjectively, or quantitatively do we get the better artifact reduction compared to the regular method(s).
    6. Ergonomics - Is the new software easier to work or offer more information more cleanly than the regular software
    7. Patient comfort - Subjectively, does the new software and/or hardware make the patient's MRI experience more comfortable.
