Myocarditis, Takotsubo Cardiomyopathy
Manganese-Enhanced Magnetic Resonance Imaging (MEMRI) in Ischaemic, Inflammatory and Takotsubo Cardiomyopathy (MEMORY)
Manganese is a calcium analogue which actively enters viable cells with intact calcium-handling mechanisms and its uptake is evident by an increase in MRI-detectable T1 relaxivity of tissues.

- Trial name
- MEMORY (NCT04623788)
- Testing
- Cardiac MRI
