详细描述
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 constantly being improved, new machines replace old machines, software is updated and improved as are the devices used to produce better MRI images.

结局指标
主要结局
Improvement in quality of MRI studies in Neuroradiology
时间窗: 1 year
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.
