Overview
Radionuclide scanning, has been used in diagnosis of sarcoidosis and evaluation of organ involvement.
Other imaging findings
Radionuclide scanning, has been used in diagnosis of sarcoidosis and evaluation of organ involvement[1]
Gallium scan
Gallium scanning has been studied as a method for detection of inflammation[2][3]. It also, can aid in identifying potential biopsy sites.
- Lambda sign: radionuclide uptake in right paratracheal and bilateral hilar areas is highly supportive for diagnosis of sarcoidosis.
- Panda sign: radionuclide uptake in parotid and lacrimal glands, is highly supportive for diagnosis of sarcoidosis[4]
