[A preliminary study of percutaneous ethanol injection therapy for hepatocellular carcinoma: evaluation of the ethanol diffusion area by the ethanol mixed with gadolinium].
To evaluate the ethanol diffusion area after Lipoidalization in 3 patients with advanced HCC treated by Lipoidalization-PEIT combination therapy, 99.9% ethanol mixed with Gadolinium was used for PEIT (Gd-PEIT). T1-weighted MR images wear obtained 1 hr after Gd-PEIT. The area of homogeneous hyperintense change on T1-weighted MR images was taken to be the ethanol diffusion area. In all 3 patients, homogeneous hyperintensity throughout the tumor over the capsule was recognized on T1-weighted MR images after treatment. The results suggests that T1-weighted MR images after Gd-PEIT provide a valuable tool by which to directly evaluate the ethanol diffusion area for advanced HCC treated by Lipoidalization followed by PEIT.
