Abstract
Currently, the following techniques are used to support the diagnosis, assess the severity, and monitor the course and response to treatment in patients with interstitial lung disease:
-
1.
Gallium-67 scanning
-
2.
Thallium-201 imaging
-
3.
Positron emission tomography (PET)
-
4.
Magnetic resonance imaging (MRI)
-
5.
High-resolution computed tomography (HRCT)
Gallium-67 citrate is a radiopharmaceutical agent that is injected intravenously. It is excreted predominately by the gastrointestinal tract. Gallium selectively accumulates in areas of infection, inflammation, and neoplasm. The test has been used to evaluate adenopathy and parenchymal disease caused by sarcoidosis. Leung et al. showed a significant correlation between the intensity of gallium uptake and the extent of nodular disease or parenchymal consolidation. It is also helpful in assessment of the extent of extrathoracic sarcoidosis, and it could also be of diagnostic value if Panda or Lambda signs are detected (Figure 3.1).
