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).
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
Example
TMPG 3 - Left Anterior Descending Artery
