Clinical expert consensus document on standards for lower extremity artery disease of imaging modality from the Japan Endovascular Treatment Conference.

Imaging modalities have developed to provide precise information in the assessment of lower extremity artery disease (LEAD), including both quantitative measurements and morphological assessment. However, a lack of standardization for the evaluation methods introduces inconsistency and potential risk. This consensus document from Japan Endovascular Treatment Conference (JET) summarizes the methods of measurement and assessment of intravascular ultrasound (IVUS), optical frequency domain imaging (OFDI), and angioscopy. We propose standardized approaches for the evaluation of these modalities in endovascular therapy (EVT).
