SPECT-CT: applications in musculoskeletal radiology

Area of Science:

• Radiology
• Nuclear Medicine
• Musculoskeletal Imaging

Background:

• Integrated single photon emission CT (SPECT)-CT combines functional (SPECT) and anatomical (CT) imaging.
• It offers technical advantages for image fusion compared to separately acquired studies.
• Musculoskeletal radiology benefits from advanced imaging techniques for diagnosis.

Purpose of the Study:

• To review the technique, principles, and applications of integrated SPECT-CT in musculoskeletal radiology.
• To evaluate the current evidence supporting SPECT-CT in diagnosing bone conditions.
• To illustrate clinical applications with case examples.

Main Methods:

• Systematic review of existing evidence on SPECT-CT in musculoskeletal radiology.
• Analysis of technical aspects and basic science principles.
• Presentation of illustrative clinical cases.

Main Results:

• SPECT-CT demonstrates potential benefits in evaluating both malignant and benign musculoskeletal conditions.
• It improves diagnostic sensitivity and specificity by reducing interpretation ambiguity compared to SPECT alone.
• The technology offers enhanced image fusion capabilities.

Conclusions:

• Integrated SPECT-CT shows promise for improving diagnostic accuracy in musculoskeletal radiology.
• Further research is required to compare SPECT-CT with MRI for key indications.
• The evidence base for SPECT-CT in this field is still developing.
