Condition | Cardiac magnetic resonance imaging features |
Myocardial infarction | < 1 mo |
Myocardial oedema present on T2-weighted images, T2 mapping and T1 mapping | |
Microvascular obstruction revealed as a hypointense core within hyperintense infarct zone in area of LGE | |
Infarct size can be calculated using pre and post-contrast T1-weighted mapping and ECV assessment | |
Myocardial necrosis/scar by LGE in a subendocardial or full-thickness pattern within a coronary artery territory | |
Additionally at < 6 mo | |
T2-weighted hyperintensity on double inversion recovery turbo spin echo | |
Takotsubo syndrome | Can help distinguish coexisting CAD or acute myocarditis LGE typically absent |
Myocardial oedema present on T2-weighted images, T2 mapping and T1 mapping | |
Accurate assessment of WMAs on cine imaging | |
Can be useful to identify ventricular thrombus | |
Myocarditis | Inflammatory hyperaemia demonstrated on T1-weighted images |
Myocardial oedema on T2-weighted images | |
Myocardial necrosis/scar by LGE in a subepicardial or mid-wall pattern | |
Greater T1 and T2 increases with acute inflammation | |
Pericardial effusion | |
COVID-19 related cardiac dysfunction | Features similar to that of acute myocarditis |
Myocardial oedema on T2-weighted images | |
Myocardial necrosis/scar by LGE in a subepicardial or mid-wall pattern | |
Myocardial fibrosis using T1-weighted mapping and ECV assessment | |
Can be useful to identify ventricular thrombus and pericardial effusion | |
Athlete’s heart | LVH typically < 12 mm |
Lower ECV with LVH compared to HCM | |
RV dilatation seen on cine imaging | |
LGE focal and generally at the RV insertion points |
Two out of three criteria must be met to be consistent with myocardial inflammation: |
Regional or global myocardial signal intensity increase in T2-weighted images |
Increased global myocardial early gadolinium enhancement ratio between myocardium and skeletal muscle in gadolinium-enhanced T1-weighted images |
At least one focal lesion with nonischaemic regional distribution in inversion recovery-prepared gadolinium enhanced T1-weighted images (late gadolinium enhancement) |
