Application of gemstone spectral imaging for efficacy evaluation in hepatocellular carcinoma after transarterial chemoembolization

Figure 3 Metastasis to the medial segment of the left lobe of the liver after transcatheter arterial chemoembolization for primary hepatocellular cancer. A: Conventional computed tomography revealed that the left lobe metastasis had no obvious enhancement; B: Iodine (water) based image showed a small amount of contrast medium entry to the left lobe metastasis, suggesting slight enhancement; C: Iodine (water) based image showed equidensity of the left lobe metastasis; D: Digital subtraction angiography confirmed tumor stain in the left lobe metastasis in parenchymal phase (arrow).
