Abstract

PURPOSE
Lipiodol CT is a important modality for the diagnosis of hepatocellular carcinoma and compared is usually performed at 2-3 week after Lipiodol injection. Therefore, we assessed and the diagnostic value and merits of immediate CT after chemoembolization from there of 2-3 week delayed Lipiodol CT.
MATERIALS AND METHODS
Thirty three cases of chemoembolization which were performed both immediate CT after chemoembolization and 2-3 week delayed Lipiodol CT were reviewed retrospectively. They were divided into four grades according to pattern of lipiodol uptake by three radiologists. The diagnostic value of immediate Lipiiodol CT was compared to delayed Lipiodol CT.
RESULTS
Grade 0 was two cases(3.0%) and Grade 1 was seven cases(21.2%). In the cases of Grade 2(23/33, 69.7%) tumor uptake could be dishng wished from parenchymal uptake of Lipiodol by its density and pattern. Tumor uptake showed dense and homogeneous pattern, but parenchymal uptake revealed less dense and hepatoram-like wedge shaped pattern. Lipiodol uptake of tumor in Grade 3(1/24, 3.0%) was equal to that in delayed Lipiodrl CT. Grade 3 and 2(72.7%) of the immediate Lipiodol CT were not inferior to delayed Lipiodol CT in its diagnostic value.
CONCLUSION
The immediate Lipiodol CT could make rapid establishment of treatment plan and are expected to be more convenient than delayed CT for the patients.
