syngo.via MR Cardiac Analysis Workflow (VA30) 1. Functions of MR Cardiac Analysis Workflow:  Reading the MR Cardiac morphology and flow images (Included with MR General Engines license)  Viewing the MR Cardiac function, perfusion and delay enhancement with structured report (Included with MR General Engines license)  Calculate the function parameter like EF, LV mass est. with the license MR cardiac function (Included with MR Cardiac Function license)  Flow evaluation in aorta and CSF to calculate the velocity, flow, peak velocity and net flow of the contour (Included with MR Cardiac Flow license) 2. MR Cardiac Analysis workflow  Open the patient using “assign workflow” or “view as read-only with” to the MR Cardiac Analysis workflow o When using the Assign workflow feature, do not open the patient until the status is “Ready to read.”  Note: Do not assign a workflow until the scan is complete and all required images have been sent to syngo.via. Do not interact with the system while the progress bar is visible. MM Unco + C1 Bone Last Name *cardiac* Date of Birth MM Onco + CT Vascular + - 2 Study Date and Ti ...

Overview of the MR Cardiac Analysis Workflow MR Cardiac Analysis There have three advanced analysis tasks integrated in the cardiac analysis workflow. MR Cardiac Reading 20 MR Cardiac Reading is general reading task, include overview, functional, dynamic, tissue characterization, Overview combined and flow reading step. Functional MR Cardiac Function is a software to diagnosis the left ventricular and right ventricular function. Tissue Characterization MR Flow Quantification is a software to analysis the Combined phase contrast images to calculate the velocity parameter etc. Flow MR Cardiac Function O MR Flow Quantification 4. MR Cardiac routine reading A. Overview: The overview step provides a comprehensive view of the images sorted by their time stamp. It is not possible to load a prior study into MR Cardiac Analysis for comparison studies, a new patient folder must be opened instead.

MR Cardiac Function  The ventricles are covered by short and long axis cine slices which are used to provide automatic contours of the epi and endocardial borders, allowing calculation of the left ventricle blood volume and muscle mass for each slice.  The software will segment the contour automatically, however the user can define the contour themselves using the following steps: o Define Apical Extent: defines the extent of the apex on the Short Axis (SAX), End Diastole (ED), and End Systole (ES) phases o Define LV Blood Pool: defines the LV base plane when only SAX images are used for calculation (similar to Argus calculation) o Define RV Insertion Point: needed for defining segments for the AHA model o Define Base Plane: defines the base plane of the mitral valve on long axis cine images for ED and ES phases o Refine the segmentation: allows user to modify, delete, draw, or automatically adjust contours o RV analysis: Allows the user to manually create contours for the right ventricle MR Cardiac Analysis Time Volume Cardiac Via Case3-1 Cardiac Via Case3-1 313131 313131 > MR Cardiac Reading *11/20/1972.
