  • Title: Lipiodol enhanced CT scanning in assessment of hepatocellular carcinoma.
    Author: Raby N, Karani J, Michell M, Gimson A, Nunnerley H, Williams R.
    Journal: Clin Radiol; 1989 Sep; 40(5):480-5. PubMed ID: 2551562.
    Abstract:
    We studied 20 patients with computed tomography (CT) following the intra-arterial injection of Lipiodol. Comparison with conventional CT, angiography and plain abdominal radiographs revealed additional satellite tumours in four patients. Technical difficulties occurred in selective hepatic arterial catheterisation and in satisfactory delivery of Lipiodol to all segments of the liver in a third of our patients. Plain abdominal radiographs following Lipiodol injection are inadequate in our experience in assessing tumour mass and distribution; we failed to demonstrate retention of Lipiodol by tumour tissue for longer than a few weeks in any case. The pattern of Lipiodol uptake within the tumour is not related to histology but to the vascular supply and size of the tumour. Our findings do not accord with the Japanese experience and this small study suggests that Lipiodol enhanced CT should be reserved for patients with small tumours in non-cirrhotic livers who are being considered for resection of their tumour. Such patients are likely to be encountered rarely in UK practice.
