Twenty patients were examined with CT of the liver before, during, and 4 to 6 hours after i.v. administration of 60 g iodine (200 ml iohexol). The attenuation of normal liver parenchyma was measured. The mean attenuation of normal liver parenchyma on nonenhanced scanning was 62.6 HU and on delayed scanning 78.7 HU. It seems that iohexol is a suitable contrast medium for delayed scanning of the liver.
对20名患者在静脉注射60克碘（200毫升碘海醇）之前、注射期间以及注射后4至6小时进行肝脏CT检查。测量正常肝实质的衰减值。未增强扫描时正常肝实质的平均衰减值为62.6 HU，延迟扫描时为78.7 HU。碘海醇似乎是肝脏延迟扫描的合适对比剂。
