      Cardiac magnetic resonance imaging (CMR) is increasingly used for myocardial tissue characterization in patients presenting with acute coronary syndrome and unobstructed coronary arteries on coronary angiography.

      The role of cardiovascular magnetic resonance in takotsubo syndrome.
      CMR imaging utilises the magnetic properties of hydrogen protons within a magnetic field. Longitudinal (T1) and transverse (T2) mapping are evolving CMR sequences, which measure the rapidity of protons to re-equilibrate after magnetisation inversion. This is largely determined by water content and so enables quantitative assessment of myocardial tissue characterization such as edema and fibrosis.
