## Indications for use
MR Diffusion Perfusion Mismatch V1.0 is an automatic calculation tool indicated for use in radiology. The device is an image processing software allowing computation of parametric maps from (1) MR Diffusion-weighted imaging (DWI) and (2) MR Perfusion-weighted imaging (PWI) and extraction of volumes of interest based on numerical thresholds applied to the aforementioned maps. Computation of mismatch between extracted volumes is automatically provided. The device is intended to assist trained radiologists and surgeons in the imaging assessment workflow by extraction and communication of metrics from MR Diffusion-weighted imaging (DWI) and MR Perfusion-weighted imaging (PWI). The results of MR Diffusion Perfusion Mismatch V1.0 are intended to be used in conjunction with other patient information and, based on professional judgment, to assist the clinician in the medical imaging assessment. Trained radiologists and surgeons are responsible for viewing the full set of native images per the standard of care. The device does not alter the original medical image. MR Diffusion Perfusion Mismatch V1.0 is not intended to be used as a standalone diagnostic device and shall not be used to take decisions with diagnosis or therapeutic purposes. Patient management decisions should not solely be based on MR Diffusion Perfusion Mismatch V1.0 results. MR Diffusion Perfusion Mismatch V1.0 can be integrated and deployed through technical platforms, responsible for transferring, storing, converting formats, notifying of detected image variations and display of DICOM imaging data.
