Tissue characterisation using intravascular radiofrequency data analysis: recommendations for acquisition, analysis, interpretation and reporting

This document suggests standards for the acquisition, measurement, and reporting of radiofrequency data analysis (virtual histology - VH) intravascular ultrasound (IVUS) studies. Readers should view this document as the authors' best attempt in an area of rapidly evolving investigation, an area where rigorous evidence is not yet available or widely accepted. Nevertheless, this document is based on known pathologic data as well as previously reported imaging data; where practical, this data is summarised in the current document, a document which will also include recommendations for future evolution of the technology.
