Model Predicting the Likelihood That IBLs Identified on 18F-DCFPyL PET/CT at 2 Hour of Uptake Are Benign or Malignant (n = 79)
Other PSMA-avid bone findings | IBL location | IBL SUVmax | Likelihood of interpretation | Interpretation accuracy |
---|---|---|---|---|
No bone metastases | Typical | <5 | 81.0% benign | True positive (n = 17); false negative (n = 4) |
No bone metastases | Typical | ≥5 | 94.7% malignant | True positive (n = 18); false positive (n = 1) |
No bone metastases | Atypical | <5 | 94.4% benign | True negative (n = 17); false negative (n = 1) |
No bone metastases | Atypical | ≥5 | 100% malignant | True positive (n = 8) |
Bone metastases | Any | <5 | 77.8% malignant | True positive (n = 7); false positive (n = 2) |
Bone metastases | Any | ≥5 | 100% malignant | True positive (n = 4) |
