Abstract:
Purpose To investigate the diagnostic value of the arrhythmogenic right ventricular dysplasia (ARVD) using multi-slice spiral CT (MSCT). Materials and Methods Thirty-four patients who were suspected as ARVD received right ventricular radiography, including 16 ARVD patients and 15 non-ARVD patients regarded as control group. The structural and shaped change of heart on reconstructed images of long axis, short axis and four cavity surface and analyze were observed, and MSCT features of right ventricular radiography characteristics were analyzed for ARVD patients. Results Sixteen cases of ARVD were correctly diagnosed by MSCT, and 14 cases had fatty infiltration including 11 cases of apex of heart, 8 cases of inferior wall, 5 cases of anterior wall, 5 cases of anterior wall of funnel area, 3 cases of diagram, 4 cases of papillary muscle, 6 cases of muscular trabecula and moderator band and 1 case of whole right ventricular free wall. Five cases showed scallop sign, 16 cases excessive trabecular change, 11 cases thinned changes, and 16 cases enlarged changes of right ventricular wall. Conclusion MSCT features of right ventricular for ARVD have relative diagnostic characteristics, and the scallop sign and excessive trabecular change of right ventricular wall are its specific imaging characteristics.
