E-073 High Resolution Magnetic Resonance Imaging of Intracranial Aneurysms Treated by Flow Diversion

The use of flow diverters to treat intracerebral aneurysms is highly successful with a low rate of morbidity of mortality. One of the primary concerns following endovascular aneurysm treatment is recurrence, and close imaging followup is often required. High resolution MRI is being employed in an increasingly wide variety of pathologies, but its use as a surveillance tool following flow diversion has not been extensively explored. We present three cases where high resolution MRI was performed following flow diversion for intracranial aneurysms and discuss its utility in this patient population.Abstract E-073 Figure 1A) Pre-flow diversion 3D T1w Black Blood pre-contrast image; B) Post-flow diversion 3D T1w Black Blood pre-contrast imageAbstract E-073 Table 1MRI sequence parametersMRI sequenceTR/TE (ms)FOV (mm2)MatrixThickness (mm)Scan time (min:sec)3D TOF22/3.6200x181384x3310.56:503D DANTE T1w BB SPACE800/21162x162196x1920.85:473D T2w BB SPACE1000/118200x200384x3800.54:18DisclosuresJ.
