• Comparison of either Cervical Spine, Head, Temporal Bone or Vasculature Treated with Metallic Implants Imaged with Computerized Tomography (CT) Imaging or Magnetic Resonance Imaging or Cerebral Angiogram to a MRI Zero Echo Time (ZTE) MRI Sequence. (ZTE MRI) Rochester, Minn.

  The purpose of this study is to demonstrate the use of 3D ZTE imaging of the cervical spine to assess osseous neural foraminal stenosis and directly compare it to CT. Other objectives will include evaluation of ossification of the posterior longitudinal ligament, ossification of disc herniations, and comparison of ZTE derived imaging of pedicle morphology to the current reformats provided by CT. The ability to image metallic hardware with ZTE will also be assessed, if present; 56 participants.  Other cohorts being added is for those who are returning for aneursym ablation follow-up with medically indicated head MRI (adding reserach ZTE sequence) and a head angiogram 100 participants; ZTE MRI of C-Spine with or without head MRI for those having migraine assessment, 30 participants; ZTE MRI Head of temporal bone for pre or post cochlear assessment, 30 participants; ZTE MRI of Venous Stenting comparison to angiogram, 30 participants.  Total 246 participants.

• Evaluation of Non Significant Risk Operation Magnetic Resonance Imaging for MR Guided Ablation using the Philips MRI Rochester, Minn.

  The objective of this proposal is to evaluate MRI hardware and software features that have potential to improve the interventional MRI (iMRI) practice.
