Letter to the Editor Focal myocardial fibrosis and edema in acute myocarditis demonstrated by multislice computed tomography

Endomyocardial biopsy has provided a method for assessing the presence of myocarditis in patients [1,2]. But biopsy studies have produced highly variable results, with the incidence of myocarditis ranging from 0% to 80% [3]. This difference may be due to patient selection [4], differences in diagnostic criteria between studies, and differences between the elapsed time from biopsy to the onset of acute myocarditis. Furthermore, occurrence of focal lesions of myocardium in myocarditis and lack of information regarding such focal lesions during biopsy may
