Report

Report format By finding By segment By wall

Only what you score is reported. To state that there is no LGE, mark segments No LGE; in the LGE view, Select unscored picks every segment without an LGE call.

Segment model and sources

AHA 17-segment model

Basal 1–6 · Mid 7–12 · Apical 13–16 · Apex 17

Polar plot as in the AHA statement: anterior at the top, septum on the left, lateral wall on the right, apex in the center. The By wall report groups segments as anterior (1, 7, 13), septal (2, 3, 8, 9, 14), inferior (4, 10, 15), lateral (5, 6, 11, 12, 16) and apex (17).

Reporting LGE

LGE is described by segment, by the layer it involves (subendocardial, mid-myocardial, subepicardial or transmural) and by its extent through the wall thickness. Segments are reported only when scored; choose No LGE to state that a segment has no enhancement.
