Comparison of short and long axis T1 and ECV maps in patients with myocarditis

Methods This study included 50 patients with clinically suspected myocarditis, who underwent CMR at 1.5 Tesla. T1 quantification was performed on three short (basis, center, apex) and on three long axis slices (2-, 3and 4-chamber orientation), respectively. The modified Look-Locker inversionrecovery (MOLLI) sequence was used before and 15 minutes after administration of 0.075 mmol/kg GadoliniumBOPTA. Native T1, post-contrast T1 and extracellular volume (ECV) maps were calculated using a dedicated plug-in written for the OsiriX software. Mean native and post-contrast T1 as well as ECV were obtained from the three short and long axes, respectively.
