Aims and objectives: Cardiac magnetic resonance (CMR) imaging is an important non-invasive diagnostic tool with high sensitivity and specificity in detecting myocarditis 1-12. When compared to endomyocardial biopsy (EMB), CMR has a higher diagnostic accuracy in the early, focal phase of myocarditis, by detecting ar[...]

Methods and materials: PATIENT CHARACTERISTICS    We prospectively evaluated 32 consecutive patients (3 women, 29 men, median age 35 years) in the cardiology department of our institution, from March 2014 to June 2016, with clinical suspicion of acute myocarditis.  All patients presented with symptoms of [...]

Results: CMR imaging during the acute phase of myocarditis revealed areas of oedema on STIR sequence in all 32 patients (100%), in 26 (82%) affecting the basal inferior (AHA segment 4) and basal inferolateral segment (AHA segment 5) with subepicardial and mid-wall involvement. In 18 patients (56%) areas of h[...]

Conclusion: During the acute phase of myocarditis, CMR revealed changes predominantly involving AHA segments 4 and 5 in all STIR and Late Gadolinium Enhancement (LGE) sequences, while  EGE sequences revealed areas of hyperaemia in 56% of patients.  At baseline study, the extent of myocardial oedema an[...]
