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

Figure 1 Hepatocellular cancer in the caudate lobe after transcatheter arterial chemoembolization. A: Iodine (water) based image. The effective iodine content of the defect of iodine deposition (154.10 ± 8.07) was significantly higher than that for normal liver parenchyma and the aorta (67.36 ± 4.87), revealing no residual tumor; B: Digital subtraction angiography image revealed no tumor vessels or stain, and obvious iodized oil deposition was visible (arrow).
