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

Figure 2 Giant hepatocellular cancer in the lateral borders of the left and right liver lobes after transcatheter arterial chemoembolization. A: The computed tomography (CT) value of the defect of iodine deposition was comparable to that of normal liver parenchyma in conventional CT image, and there was no obvious enhancement; B: Digital subtraction angiography revealed enlarged tumor blood vessels and tumor stain in the defect of iodine deposition.
