Bone-RADS Calculator v. 2023

ACR's Bone Reporting and Data System for Bone Tumor Risk Stratification and Management (BONE RADS ™), released October 2023

bone-RADS
Can the bony lesion be fully assessed?
Is there a pathological fracture?
Is there evidence of extra-osseous soft tissue mass?
Does the patient have a known primary cancer?
How is the lesion’s margination / zone of transition?
Is there periosteal reaction?
Is there endosteal scalloping?

Score & recommendations:

Bone-RADS 0. Recommend further evaluation with additional radiographic views or CT/MRI.

Copy to Clipboard

Incompletely characterized, Risk cannot be adequately predicted

Score & recommendations:

Bone-RADS 1. If patient is asymptomatic, consider work up to be complete or alternatively, continue annual surveillance to ensure expected stability. If patient is symptomatic or clinical presentation changes, consider orthopedic oncology referral and further evaluation with CT/MRI.

Copy to Clipboard

Very low risk of malignancy (Pathognomonic benign bone lesion)

Score & recommendations:

Bone-RADS 2. Recommend follow-up imaging in 3-6m vs. further evaluation with CT/MRI. Consider orthopedic oncology referral for surveillance or treatment of benign tumor.

Copy to Clipboard

Low risk of malignancy (probably benign)

Score & recommendations:

Bone-RADS 3. Recommend orthopedic oncology referral and further evaluation with CT, MRI, or bone scan.

Copy to Clipboard

Intermediate risk of malignancy (potentially malignant)

Score & recommendations:

Bone-RADS 4. Recommend orthopedic oncology referral and further evaluation with CT, MRI, or bone scan.

Copy to Clipboard

High risk of malignancy (malignant until proven otherwise)

    It seems that this calculator incorrectly assigns 4 points for a soft tissue mass, while according to the ACR’s page for Bone-RADS it should assign 2 points only. May you please verify this and fix the bug? Thank you.

    Thank you for your reply! Now I realized that the cause of the confusion is on the ACR’s page for Bone-RADS, because the presence of a soft tissue mass is differently assessed in two documents:
    – 2 points in the “Bone-RADS TM v2023 Assessment Categories and Scoring System”
    – 4 points in the “Bone-RADS TM – Radiography Imaging Report Template for Potentially Neoplastic Bone Lesions”.
    Is there a way to check which document contains an error?
