ACR appropriateness criteria on metastatic bone disease

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Metastatic disease to bone is a common complication of various cancers.
• Accurate imaging is crucial for patient management, including screening, staging, and surveillance.
• Multiple imaging modalities exist, each with potential benefits and limitations.

Purpose of the Study:

• To provide evidence-based recommendations for the appropriate use of imaging in patients with suspected or documented metastatic bone disease.
• To review clinical scenarios involving various cancer types and stages.
• To guide clinicians in selecting the most suitable imaging modality for specific situations.

Main Methods:

• The ACR Appropriateness Criteria((R)) Expert Panel on Musculoskeletal Radiology reviewed clinical scenarios.
• Evidence-based consensus was reached on the utility of various imaging modalities.
• Modalities considered include bone scintigraphy ((99m)Tc), MRI, CT, radiography, and PET scans.

Main Results:

• No single imaging modality is consistently optimal for all patients with bone metastases.
• The choice of imaging depends on the specific tumor type, stage, and clinical presentation.
• In certain cases, imaging may not be indicated.

Conclusions:

• Tailored imaging selection is essential for effective management of metastatic bone disease.
• Recommendations address diverse scenarios, from early-stage breast cancer to multiple myeloma and osteosarcoma.
• A case-by-case approach, guided by evidence-based criteria, ensures appropriate use of imaging resources.
