Figure 1 CTAP image obtained in a 40-year-old man with liver micro-cancer shows a punctuate perfusion defect in right lobe.

Figure 2 CTHA image obtained on the same slice to Figure 1, the micro-tumor manifested as an small round enhancement nodule.

Figure 3 CTHA in a 45-year-old man shows a micro-cancer with a diameter of 0. 3 cm.

Figure 4 A punctuate lipiodol deposit focus with 0. 2 cm in diameter is shownon Lp-CT in a 28-year-old woman with elevate d serum AFP level of 860 μg/L detects which was not detected by CTAP and CTHA.

Figure 5 CTHA in a 35-year-old man shows two punct uate non-pathologic enhancement foci on the edge of right lobe.
