Not All Plaque and Plaque Analysis Software Are the Same

ACC/AHA guidelines highlight the importance of plaque, particularly high-risk plaque, as a driver of major adverse cardiovascular events (MACE)1

  • Plaque silently builds up over decades until MACE
  • Determining the amount and type of atherosclerosis (plaque) present may enable earlier diagnosis and facilitate precision treatment2,3

Assessing atherosclerosis is challenging due to limitations of current image processing4
