In this graphic, a comparison is presented between intravascular imaging (IVUS) and Digital Subtraction Angiography (DSA) in patients with peripheral artery disease (PAD), focusing on different locations. The study’s findings indicate that visual estimation measurements obtained from angiographic images were consistently smaller in all arterial segments compared to those obtained from IVUS assessment. This highlights the discrepancy in size estimation between the two imaging modalities, emphasizing the potential for IVUS/intracoronary imaging to provide more accurate and precise measurements in evaluating PAD across various arterial segments.
