Accurately prescribe the initial four-chamber long-axis localizer; its row is open.\n\nANATOMICAL CRITERIA:\nBoth ventricles and both atria should be represented in one long-axis plane without foreshortening the LV apex. The LV apex and midpoint of the LV–LA junction should be in plane. Where available, basal ventricular SAX anatomy should support a four-chamber orientation across the interventricular septum toward the RV free wall, rather than an oblique two-chamber or outflow-tract view. The plane should be approximately perpendicular to the SAX planes and consistent with any acquired long-axis references.\nThese XCAT reference images are diastolic; valve leaflets may not be visible. Use the midpoint of the LV–LA junction and the LV apex to define the LV long axis. A short-axis plane is perpendicular to that long axis.\n\nENDPOINT: The requested prescription has been successfully submitted. Return done at that point; later workline rows are outside this task. Completion of later acquisitions is not required.", | |
