摘要：
Disclosed are contrast agents of the formula
or pharmaceuticaoly acceptable salts thereof,
contained in aqueous compositions and methods for their use in diagnostic radiology of the gastrointestinal tract wherein
Z = H, halo, C₁-C₂₀ alkyl, cycloalkyl, lower alkoxy, cyano, where the alkyl and cycloalkyl groups can be substituted with halogen or halo-lower-alkyl groups;
R = C₁-C₂₅ alkyl, cycloalkyl, or halo-lower-alkyl, optionally substituted with halo, fluoro-lower-alkyl, aryl, lower-alkoxy, hydroxy, carboxy, lower-alkoxy carbonyl or lower-alkoxy-carbonyloxy, (CR₁R₂) p - (CR₃ = CR₄) m Q, or (CR₁R₂) p - C ≡ C - Q;
R₁, R₂, R₃ and R₄ are independently lower-alkyl, optionally substituted with halo;
x is 1-4;
n is 1-5;
m is 1-15;
p is 1-10; and
Q is H, lower-alkyl, lower-alkenyl, lower-alkynyl, lower-alkylene, aryl, or aryl-lower alkyl.
