Hepatic CT scans in 61 consecutive patients with proved liver metastasis performed both before and after administration of contrast medium were subjected to blind analysis by two observers. In 10 patients (16%) hepatic lesions were better defined before CE and focal hepatic lesions were diagnostically visible only before CE in 8 patients (13%). Lesions were better defined following CE in 16 patients (26%) but in only 2 cases (3%) were lesions diagnostically visible only after CE. The majority of lesions [35 (58%)] were equally well visualized before and after CE.
对61例经证实有肝转移的患者在注射造影剂前后均进行了肝脏CT扫描，并由两名观察者进行盲法分析。10例患者（16%）的肝脏病变在增强扫描前显示更清晰，8例患者（13%）的局灶性肝脏病变仅在增强扫描前能被诊断性显示。16例患者（26%）的病变在增强扫描后显示更清晰，但仅2例患者（3%）的病变仅在增强扫描后能被诊断性显示。大多数病变[35例（58%）]在增强扫描前后显示效果相同。
