All about that flow..not pressure!

All About the Flow - No PressureCongratulations to Dr. Paul Morris whose image showing different aspects of coronary artery physiology (pressure and flow) in a diseased coronary artery has been shortlisted for this year’s BHF Reflections of Research Prize.

The four images show different aspects of coronary artery physiology (pressure and flow) in a diseased coronary artery. This image is generated by computer simulation from the angiogram of a patient with coronary artery disease. The narrowed segment is the area of disease. The colours reflect pressure changes (red high, green low), the lines are flow streamlines demonstrating flow direction, and the arrows represent the speed of blood flow. This computed information is useful when making decisions about patients' treatment and cannot be acquired with standard clinical methods. Note how the blood flow accelerates across the disease and the pressure drops.
