1.5 T augmented reality navigated interventional MRI: paravertebral sympathetic plexus injections.

Purpose: The high contrast resolution and absent ionizing radiation of interventional magnetic resonance imaging (MRI) can be advantageous for paravertebral sympathetic nerve plexus injections. We assessed the feasibility and technical performance of MRI-guided paravertebral sympathetic injections utilizing augmented reality navigation and 1.5 T MRI scanner.

MR-guided perineural injection of the ganglion impar: technical considerations and feasibility.

Objective: Perineural ganglion impar injections are used in the management of pelvic pain syndromes; however, there is no consensus regarding the optimal image guidance. Magnetic resonance imaging (MRI) provides high soft tissue contrast and the potential to directly visualize and target the ganglion. The purpose of this study was to assess the feasibility of MR-guided percutaneous perineural ganglion impar injections.

MR-guided vertebroplasty with augmented reality image overlay navigation.

Purpose: To evaluate the feasibility of magnetic resonance imaging (MRI)-guided vertebroplasty at 1.5 Tesla using augmented reality image overlay navigation.

Materials And Methods: Twenty-five unilateral vertebroplasties [5 of 25 (20%) thoracic, 20 of 25 (80%) lumbar] were prospectively planned in 5 human cadavers.

Augmented reality visualization using image overlay technology for MR-guided interventions: cadaveric bone biopsy at 1.5 T.

Purpose: The purpose of this study was to prospectively test the hypothesis that image overlay technology facilitates accurate navigation for magnetic resonance (MR)-guided osseous biopsy.

Materials And Methods: A prototype augmented reality image overlay system was used in conjunction with a clinical 1.5-T MR imaging system.

Augmented reality visualization with use of image overlay technology for MR imaging-guided interventions: assessment of performance in cadaveric shoulder and hip arthrography at 1.5 T.

Purpose: To prospectively assess overlay technology in providing accurate and efficient targeting for magnetic resonance (MR) imaging-guided shoulder and hip joint arthrography.

Materials And Methods: A prototype augmented reality image overlay system was used in conjunction with a clinical 1.5-T MR imager.

Augmented reality visualisation using an image overlay system for MR-guided interventions: technical performance of spine injection procedures in human cadavers at 1.5 Tesla.

Objectives: To prospectively assess the technical performance of an augmented reality system for MR-guided spinal injection procedures.

Methods: The augmented reality system was used with a clinical 1.5-T MRI system.

Augmented reality visualization with image overlay for MRI-guided intervention: accuracy for lumbar spinal procedures with a 1.5-T MRI system.

Objective: The purpose of this study was to prospectively evaluate the accuracy of an augmented reality image overlay system in MRI-guided spinal injection procedures.

Materials And Methods: An augmented reality prototype was used in conjunction with a 1.5-T MRI system.

MR neurography: past, present, and future.

Objective: MR neurography (MRN) has increasingly been used in clinical practice for the evaluation of peripheral nerve disease. This article reviews the historic perspective of MRN, the current imaging trends of this modality, and the future directions and applications that have shown potential for improved imaging and diagnostic capabilities.

Conclusion: MRN has come a long way in the past 2 decades.

The application of three-dimensional diffusion-weighted PSIF technique in peripheral nerve imaging of the distal extremities.

Purpose: To evaluate whether the addition of the three-dimensional diffusion-weighted reversed fast imaging with steady state free precession (3D DW-PSIF) sequence improves the identification of peripheral nerves in the distal extremities.

Materials And Methods: Twelve MR neurography (MRN) studies of the distal upper extremity and 12 MRN studies of distal lower extremity were evaluated. From the 24 subjects who were enrolled, 10 had clinically suspected peripheral neuropathy, whereas 14 suffered from various orthopedic diseases and had no clinical signs of neuropathy.
