A method for using iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, to provide radiopaques for various radiography purposes in connection with such techniques as X-ray applications including myelography, salpingography, lymphography and bronchography. The method first comprises selecting a compound generally categorized as a carbonate and having the general formula ##STR1## wherein R represents an alkyl group having from 1 to 10 carbon atoms and R' represents an iodinated phenyl linked directly to the ester oxygen or through an alkyl chain consisting of 1 to 3 carbon atoms. An effective amount of a pharmaceutically acceptable carbonate, as defined herein, is then placed into the subject body cavity and the particular X-ray or other study performed of this area.
使用碘芳基碳酸酯的方法,例如p-碘苄基碳酸酯,p-碘sec-苯乙基碳酸酯,p-碘苯乙基碳酸酯,p-碘苯基碳酸酯,3-(p-碘苯基)丙基碳酸酯,3-(p-碘苯基)丁基碳酸酯,2-(p-碘苄基)丁基碳酸酯和2-(p-碘苄基)-己基碳酸酯,用于在X射线应用中包括脊髓造影术、输卵管造影术、淋巴造影术和支气管造影术等各种放射学目的提供造影剂。该方法首先包括选择一种通常归类为碳酸酯的化合物,其具有以下一般公式:
其中R代表具有1到10个碳原子的烷基基团,R'代表直接连接到酯氧或通过由1到3个碳原子组成的烷基链连接的碘化苯基。然后将根据本文定义的药用可接受的碳酸酯的有效量放入受试者体腔中,并对该区域进行特定的X射线或其他研究。
