Note:—MTAE indicates the total amount of injected ethanol in the entire series of EA sessions; IES, intranodular echo staining; NoS, the number of EA sessions; VasEA, the vascularity of solid components after the final EA on follow-up US; Cx, complications; VRR, the percentage of decreased nodule volume between the original nodule before RFA and the postablated nodule on the last follow-up US after EA; LFUUS, the last follow-up US.
↵a Volume of vascularized solid components of an incompletely ablated nodule after RFA and before EA.
↵b Nodule vascularity on color and power Doppler US: no vascularity, 0; low vascularity, 1; iso-vascularity, 2; mildly increased vascularity, 3; markedly increased vascularity, 4.
↵c Intranodular echo staining (depending on the degree of nodule echogenicity due to infused ethanol): no staining (nearly complete washout), 0; poor staining (≤10%), 1; mild staining (10%–50%), 2; moderate staining (≥50%), 3.
