Overview
MRI may be helpful in the diagnosis of mediastinitis. Findings on MRI suggestive of mediastinitis include mediastinal or hilar mass, or calcifications of the central mass.[1] Pattern of involvement is essentially similar to CT scan for mediastinitis.[2]
MRI
Findings on MRI suggestive of mediastinitis include mediastinal or hilar mass, or calcifications of the central mass.[1] Pattern of involvement is essentially similar to CT scan for mediastinitis.[2] Signal characteristics include:[2][3][4]
- T1: typically heterogeneous but overall iso signal to muscle
- T2: variable with both high 3 and low 2-3 signal within the same lesion
- T1 C+ (Gd): may show heterogeneous enhancement
