Three-Dimensional Dynamic Intensity Entropy Transformation Magnetic Resonance Imaging

**Semantic type:** Diagnostic Procedure

**Definition:** An application of 3-dimensional magnetic resonance imaging (MRI) that transforms the MR T1-weighted signal, voxel by voxel, to a quantitative entropy enhancement value (qEEV) based on Shannon entropy to assess changes over time. The data is used to create a color heat map with larger MR signal changes seen as greater change along the color scale.
