Mediastinitis MRI
Introduction
Overview
Overview
MRI may be used in the diagnosis of mediastinitis. Findings on MRI suggestive of mediastinitis include mediastinal or hilar mass and calcifications of the central mass.[1] Pattern of involvement in mediastinitis is essentially similar to mediastinitis CT scan.[2] Findings on MRI suggestive of mediastinitis include heterogeneous but iso signals, mediastinal or hilar mass, and calcifications of the central mass.
