Abstract

Thirty-nine patients with liver tumors were examined using MRI at 0.5 T before and after intravenous bolus injection of either 0.1 mmol/kg (n = 18) or 0.2 mmol/kg (n = 21) of Gadolinium-Dota, using spin-echo T1- and T2-weighted sequences before injections and spin-echo or gradient-echo sequences after injection. When contrastto-noise (CN) data were normalized relative to time, optimal mean CN was observed after gadolinium injection. However, subjective study and case-by-case CN measurement showed better contrast for SE 2000/60 and CT with injection in 62% and 42% of cases, respectively.
