Angiotensin-converting Enzyme as a Predictor of Extrathoracic Involvement of Sarcoidosis.

Abstract

In sarcoidosis, extrathoracic involvement may be life threatening or indicative of poor outcome. sACE levels are easily determined and may predict extrathoracic involvement. In patients with sarcoidosis, sACE levels can be used to better define those who would benefit from FDG-PET/CT examination to detect extrathoracic involvement.
