parametric mapping
Pixel-by-pixel quantitative analysis technique that creates color-coded maps displaying tissue characteristics across the myocardium.
Full Definition
Parametric mapping is an advanced cardiac MRI technique that generates quantitative, color-coded maps by calculating specific tissue parameters for each pixel in the image. Common applications include T1 mapping (for fibrosis detection), T2 mapping (for edema assessment), and T2* mapping (for iron deposition). Each pixel's color represents a quantitative value, allowing for objective assessment of myocardial tissue composition and pathology. This technique has revolutionized cardiac imaging by providing standardized, reproducible measurements that can detect subtle changes in myocardial structure before they become apparent on conventional imaging.
Usage
Usage note: Specify the type of parametric mapping (T1, T2, T2*) when describing specific applications.
