Fig. 1From: Correlation and agreement between superb micro-vascular imaging and contrast-enhanced ultrasound for assessing radiofrequency ablation treatment of thyroid nodules: a preliminary studyThe red arrow in a indicates the ablation lesion in SMI mode. No blood flow was detected in the ablation lesion. The white arrow in b indicates the ablation lesion in CEUS mode, and no contrast agent perfusion is found in the ablation lesion. The ablation volumes in SMI mode were larger than that in CEUS modeBack to article page
