Identification of Paramagnetic Rim Lesions Using off the Shelf Phase Maps (P5-19.008)

Key Points

• This study aims to evaluate the consistency among different raters in identifying paramagnetic rim lesions using advanced MRI techniques.
• Cross-sectional design assessing two imaging techniques: T2*-weighted three-dimensional echo-planar imaging at 3 Tesla and single-echo gradient-echo derived phase images at 7 Tesla.
• Inter-rater level of agreement on paramagnetic rim lesion identification was measured.
• Utilizes phase and susceptibility-weighted imaging methods for comparative analysis.
• Detected varying levels of agreement among raters on the identification of paramagnetic rim lesions.
• Higher agreement was noted with the 7 Tesla imaging compared to 3 Tesla.
• Phase images from different scanning techniques provided insights into PRL characteristics.
