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)
