Computed tomographic arteriography in the pre-surgical evaluation of hepatic tumours

Five patients with hepatic neoplasms considered suitable for surgical resection were examined by computed tomography (CT), hepatic angiography and then a combination of angiography and CT (CTA). In each patient the tumour was more clearly defined and its extent more accurately determined than by routine CT. Three patients were spared surgery when further hepatic tumour was shown by CTA. The left lobe was shown to be free of tumour in the other two patients and surgical resection was carried out. Examination by CTA is recommended in all patients with hepatic tumours considered suitable for hepatic resection.
