Summary
Hybrid single-photon emission computed tomography/computer tomography (SPECT/CT) enhances musculoskeletal infection diagnosis. This advanced imaging offers superior anatomic localization and infection extent delineation compared to older methods.
Area of Science:
- Nuclear Medicine
- Radiology
- Musculoskeletal Imaging
Background:
- Musculoskeletal infections pose diagnostic challenges.
- Accurate localization and delineation of infection are crucial for effective treatment.
- Conventional imaging methods have limitations in complex cases.
Purpose of the Study:
- To provide an overview of hybrid SPECT/CT imaging for musculoskeletal infections.
- To highlight the clinical utility of SPECT/CT in specific scenarios.
- To discuss the advantages of SPECT/CT over conventional techniques.
Main Methods:
- Review of current literature and clinical applications of SPECT/CT in musculoskeletal infections.
- Comparison of SPECT/CT with planar scintigraphy and SPECT alone.
- Emphasis on clinical scenarios including soft tissue vs. bone infection differentiation, altered bone anatomy, and complex anatomy.
Main Results:
- SPECT/CT offers improved anatomic localization and more accurate delineation of infection extent.
- It is particularly useful for differentiating soft tissue from bone infections.
- SPECT/CT aids in assessing infected sites with underlying bone alterations and complex anatomy.
Conclusions:
- Hybrid SPECT/CT imaging is a valuable tool for diagnosing musculoskeletal infections.
- It provides superior diagnostic accuracy and aids in therapeutic strategy selection.
- Advantages include reduced inconvenience, added CT information, and improved interobserver agreement.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
