In the last few years, technological advances in MR imaging, PET detectors, and attenuation correction algorithms have allowed the creation of truly integrated PET/MR imaging systems, for both clinical and research applications. These machines allow a comprehensive investigation of cardiovascular diseases, by offering a wide variety of detailed anatomical and functional data in combination. Despite significant pathophysiologic mechanisms being clarified by this new data, its clinical relevance and prognostic significance have not been demonstrated yet.

Because this product displays a broad spectrum affinity for the MMP family, we hypothesized that it may also recognize other metalloproteinases overactivated in vulnerable atherosclerotic plaques. Therefore, this study aimed at describing, at the molecular and cellular level, the interactions between P947 and proteases of atherosclerotic plaques.
