CTICasesMyocarditis Evaluated with Dual-Energy CT
Imaging findings
Dual-energy CT of the chest performed on a 4-minute delay using low monoenergetic (40 keV) reconstructions demonstrates striking, extensive hyperenhancement of the subepicardium. Early-phase CT imaging confirms corresponding myocardial hyperemia, which correlates perfectly with a classic subepicardial late gadolinium enhancement pattern on cardiac MRI.
Key takeaways
Low monoenergetic (40 keV) dual-energy delayed-enhancement CT is highly sensitive for depicting active myocardial inflammation and hyperemia. It serves as an underutilized but powerful alternative to cardiac MRI when MR imaging is contraindicated or unavailable.
