Objective:
To analyze the characteristics of various imaging techniques for detecting brain metastases (BM) and their clinical applications.
Key Findings:
- MRI is the primary diagnostic method for BM due to its high soft-tissue resolution.
- Advanced MRI techniques improve detection of small lesions.
- CT is useful for rapid assessment but has limitations in soft-tissue resolution.
- PET imaging provides functional insights but is limited by signal-to-noise ratio.
- Multimodal fusion techniques enhance diagnostic sensitivity and specificity.
Interpretation:
Limitations:
- Conventional imaging modalities have inherent limitations and may not be applicable to all BM.
- MRI can have a higher false positive rate compared to PET in detecting small volume or early stage BM.
Conclusion:
