DEVICE: STAGE (00866463000465)

Device Description: STAGE is a MR post-processing software medical device intended for use in the visualization of the brain. STAGE analyzes input data from MR imaging systems. STAGE runs within a VM environment on hardware that meets the minimum requirements. STAGE utilizes magnitude and phase data acquired with specific parameters to generate enhanced T1 weighted images, SWI images, susceptibility enhanced images, pseudo-susceptibility maps, true SWI images, MR angiography (MRA) images, simulated T2 images, simulated T2 FLAIR images, simulated dual inversion recovery (DIR) images, and maps of T1, R2*, and proton density (PD). CROWN, introduced in STAGE, reduces noise some of these outputs, enhancing SNR and/or reducing imaging time. STAGE is indicated for brain imaging. Maximum and minimum intensity projections of some of these outputs will also be provided. The STAGE outputs can be configured to match the conventional acquisition series in MR protocols (i.e. routine brain w/) in terms of contrast, orientation and resolution. STAGE should always be used in combination with at least one other conventional MR acquisition technique (e.g. T2 FLAIR). STAGE input data can be acquired within a range of collection parameters, within shorter echo acquisitions allowing for less susceptibility affects and higher anatomic signal at the air tissue interface or with longer echo times for higher susceptibility effects around blood products and iron sources.
