Summary
Incidental liver masses require accurate characterization. This review guides the use of imaging modalities for incidentally detected liver lesions in various clinical scenarios.
Area of Science:
- Radiology
- Hepatology
- Medical Imaging
Background:
- Incidental liver masses are frequently found during imaging for other reasons.
- Accurate characterization of these lesions is crucial, especially in patients with existing cancer.
- Benign focal liver lesions are common in adults.
Framework:
- This document reviews imaging modalities for incidentally detected liver lesions.
- It discusses their use within specific clinical scenarios.
- Evidence supporting each diagnostic modality is summarized.
Implementation:
- The American College of Radiology Appropriateness Criteria provide evidence-based guidelines.
- These guidelines are developed by a multidisciplinary panel and annually reviewed.
- Methodologies like RAND/UCLA and GRADE are used to assess appropriateness.
Implications:
- This review aids clinicians in selecting appropriate imaging for liver lesions.
- It addresses situations with limited or conflicting evidence.
- Expert opinion supplements evidence when necessary for recommendations.
