Investigating Associations Between Signal Intensity of Silent MR Angiography and Hemodynamic Information From 4D Flow MRI in Brain Arteriovenous Malformation.
BACKGROUND Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. OBJECTIVES To evaluate the relationship between Silent MRA SI and 4D flow-derived hemodynamic parameters and examine whether Silent MRA-based metrics are associated with symptomatic he...
