Reliability Verification and Diagnostic Value Based on Brain Metastases of STAGE at 1.5T

As the first choice to identify brain metastases (BM), the anatomical, functional and metabolic information extracted by various MR sequences is the basis. However, synthetic MR technique mostly relies on expensive equipment and high field strength, which is challenging for primary institutions to implement. In this study, we assessment the reliability and diagnostic value based on BM of Strategically Acquired Gradient Echo (STAGE) at 1.5T. Enhanced T1W map of STAGE showed better GM/WM CNR compare with T1MPRAGE for BM identification. Reliable values and inconspicuous physiological variability were observed in the quantitative maps for various brain tissues.
