Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) have developed a one-micrometer-resolution version of the intravascular imaging technology optical coherence tomography (OCT) that can reveal cellular and subcellular features of coronary artery disease. In a Nature Medicine paper receiving advance online publication, the investigators describe how microOCT – which provides 10 times greater resolution than standard OCT – was able to show individual arterial and inflammatory cells, including features that may identify vulnerable plaques, within coronary artery samples.
