Late gadolinium enhancement (LGE) is an assessment made with cardiac magnetic resonance (CMR) imaging that includes gadolinium contrast administration. The test is done to assess for accumulation of gadolinium contrast material accumulation in the tissue with increased extracellular space to determine both left and right ventricle fibrosis (ref: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5801263/). For LGE, the assessment relates to the timing of the reading showing whether the contrast is present or not (shown as positive or negative). If the LGE is noted as present, more assessments may be done, such as presence per segment and the percentage of presence per segment. Since contrast is important to these assessments, the Procedure Agents (AG) dataset is shown with this example.
