Noninvasive identification of left ventricular involvements in arrhythmogenic right ventricular dysplasia: Comparison of123I-MIBG,201TlCl, magnetic resonance imaging and ultrafast computed tomography

We examined the feasibility of myocardial123I-MIBG,201TlCl, magnetic resonance imaging (MRI) and ultrafast computed tomography (UFCT) for the early detection of left ventricular involvements in 15 patients with arrhythmogenic right ventricular dysplasia (ARVD). Radionuclide ventriculography (RNV) and myocardial imaging with123I-MIBG,201TlCl, MRI and UFCT were performed in all 15 patients and in 10 normal subjects.
