Radial-VIBE (Radially acquired Volume Interpolated GRE) with GRASP (Golden-angle RAdial Sparse Parallel) is a novel contrast-enhanced T1Wgradient-echo sequence
• Unique k-space sampling and data acquisition parameters
• Excellent fat-suppressed motion robust images with exquisite illustration of the anatomy
• Excellent spatial resolution allows assessment of structural permeability characteristics
• An overview of the physics of Radial-VIBE and GRASP, compare it to conventional T1W-images and evaluate its role in assessing head and neck pathology
- Overview of Radial-VIBE physics and discuss its permeability characteristics
- Discuss its role in evaluating orbital anatomy and commonly seen pathology such as vascular malformations, optic neuritis and meningiomas, as well as hitherto unexplored conditions such as vitreitis
- Assess its role in evaluating skull base lesions due to its inherent fat-suppressed characteristics and excellent spatial resolution
- Discuss its role in evaluating parathyroid pathology obviating the need for dynamic CT acquisition
- Demonstrate unique permeability patterns of the normal structures in head and neck
- Discuss our early experience in assessing primary head and neck cancers utilizing permeability maps
- Distinguish normal and metastatic lymph nodes utilizing permeability patterns
