Semiquantitative Visual Scoring of 99mTc-Pyrophosphate Uptake in Myocardium Versus Ribs
Grade | Description |
---|---|
0 | No myocardial uptake and normal bone uptake |
1 | Myocardial uptake less than rib uptake |
2 | Myocardial uptake equal to rib uptake |
3 | Myocardial uptake greater than rib uptake, with mild or absent rib uptake |
