Abstract:
Objective To describe the MRI findings in patients with Acquired hepatiocerbral Degeneration(AHCD) and evaluate the role of MRI in dignosis of AHCD. Methods 26 patients with chornic hepatic failure under went brain MRI scan. Eight of these patients had abdominal MR digital subtract angiography(MRDSA) examnation. 25 patients had plasma ammonia levels test two weeks after MR exmnation. Results 22 patients had abnormal MRI findings, T 1WI demonstrated incresed signal in the globus pallidus (22/26), putmen (4/26), mesencephalon surrounding red nucleus(15/26),and in the anterior pituitary (12/26). While T 2WI demonstraied no corresponding alteration in signal intensity. Eight patients which had MRDSA showed obvious portal systemic shunts. There was positive correlation between plasam ammonia level and abnormal signal( r = 0.521 6, P
