Welcome to AmyloidAnalyzer
Load 1-hour and 3-hour DICOM files to begin analysis.
- Draw Heart ROI by clicking and dragging on the 1-hour image.
- Place Contralateral Lung ROI by clicking once on the 1-hour image (radius is locked).
- Copy ROIs to the 3-hour image, or place them manually.
- Adjust Window/Level for visualization.
- Assign Perugini visual grade at the bottom.

Perugini Visual Grade
Perugini grade: not assigned
Grade 0
no cardiac uptake
Grade 1
cardiac uptake lower than rib uptake
Grade 2
cardiac uptake equal to rib uptake
Grade 3
cardiac uptake greater than rib uptake
Retention Index (RI) = H/CL 3 h − H/CL 1 h
RI: --
