Summary
Functional imaging, including perfusion imaging, diffusion-weighted imaging (DWI), and MR proton spectroscopy (MRS), enhances musculoskeletal tumor characterization. Addressing technical challenges is key to accurate diagnosis and improved patient follow-up.
Area of Science:
- Radiology and Imaging Science
- Oncology
- Biomedical Engineering
Background:
- Conventional imaging often yields indeterminate musculoskeletal (MSK) tumors.
- Increasing clinical availability of functional imaging methods offers improved diagnostic capabilities.
- Functional imaging aids in tumor detection, characterization, and follow-up assessments.
Purpose of the Study:
- To discuss the application of functional imaging techniques in evaluating bone and soft tissue tumors.
- To highlight the importance of understanding specific protocol requirements and diagnostic pitfalls for each method.
- To address technical issues impacting data quality and comparability in MSK functional imaging.
Main Methods:
- Review of contrast-enhanced perfusion imaging protocols for MSK tumors.
- Discussion of diffusion-weighted imaging (DWI) acquisition parameters and interpretation.
- Evaluation of MR proton spectroscopy (MRS) applications and technical considerations in MSK tumor assessment.
Main Results:
- Functional imaging techniques like perfusion imaging, DWI, and MRS show significant potential in improving the characterization of indeterminate MSK lesions.
- Specific acquisition protocols and awareness of technical difficulties are crucial for reliable results.
- Current clinical indications for these advanced imaging modalities in MSK oncology are outlined.
Conclusions:
- Functional imaging methods are valuable adjuncts to conventional imaging for musculoskeletal tumors.
- Careful attention to protocol optimization and potential pitfalls is necessary to maximize diagnostic accuracy.
- Further research and standardization are needed to fully integrate these techniques into routine clinical practice.
