Objective    To discuss the utility of MRI in evaluating arrhythmogenic right ventricular cardiomyopathy (ARVC).     Methods    Nine patients of ARVC who received treatment in our hospital from January 2005 to May 2008

were retrospectively analyzed. They all underwent MRI by using GE signa 1.5 Tesla CV/I MR system. White blood technique (Fast cine sequence) were performed in short axis view

four-chamber view

and long axis view of two ventricles. Black blood techniques (Double IRFSE and Triple IRFSE) were performed in short axis view and long axis view of the right ventricle.     Results    MRI displayed thinning of the right ventricular (RV) wall (9 cases)

dilatation of the RV (8 cases)

fat signal intensity of the RV wall in DIRFS and irregular insula or continuity breaking in TIRFSE (3 cases)

dilatation of the left ventricle (LV) (2 cases)

a bit thickening of ventricular septum (1 case)

enlargement of the outflow of the RV (2 cases)

and ventricular wall aneurysm formation (2 cases). Their positions involved apex of the right ventricle (6 cases)

facies diaphragmatica (4 cases)

anterior ventricle (4 cases)

infundibulum (4 cases) and the papillary muscle of the RV (1 case).     Conclusion    Cardiac MRI is the most specific and sensitive examination technique in diagnosing of ARVC

which can present structural and functional changes and the quality

degree

range of the disease. We recommend cardiac MRI if ARVC is suspected.
