==Overview==


 
Normal entry and exit of dye from the microvasculature. There is the ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery that clears normally and is either gone or only mildly persistent during the washout phase (i.e. dye is gone or is only mildly persistent after 3 cardiac cycles and noticeably diminishes during the washout).
==Description==
 
Normal entry and exit of dye from the microvasculature. There is the ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery that clears normally and is either gone or only mildly persistent during the washout phase (i.e. dye is gone or is only mildly persistent after 3 cardiac cycles and noticeably diminishes during the washout).  
 
The 3 cardiac cycles are determined from the point when dye touches either none or only one of the arterial borders (TIMI Frame 0). Mildly persistent blush at its maximum intensity is not as intense or bright as the fully-opacified surrounding collaterals.
 
Blush which is more intense than minimal blush but less than normal blush is termed a “weak 3” and is assigned a TMPG of 3 and an intensity of 0.75.
 
*Intensity Range: 0.75 – 1

Overview

Normal entry and exit of dye from the microvasculature. There is the ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery that clears normally and is either gone or only mildly persistent during the washout phase (i.e. dye is gone or is only mildly persistent after 3 cardiac cycles and noticeably diminishes during the washout).

Example

Shown below are a static image and an animated image depicting TIMI perfusion grade 3.
