Answer :

Answers-4 This condition is sarcoidosis. Serum calcium, Serum phosphorus, Chem7 and Chem 20 and Quantitative Immunoglobulins are all used in establishing the diagnosis. Gallium scan is helpful in sarcoidosis. (Radiology of extrathoracic sarcoid ...) Gallium scan vs. Thallium scan. Gallium scan (radioactive 67Ga) is used to detect inflammation - such as in inflammatory disorders or malignancy. Thallium (radioactive 201Tl) is a potassium analogue and is used to demonstrate areas of poor perfusion. It is particularly used in cardiology to detect areas of ischaemia.
