AIM To recognize the characteristic findings of micrQliver cancer (MLC) and to evaluate the effect of CT arterial portography (CTAP) and CT hepatic arteriography (CTHA) in diagnosis of MLC. METHODS Between April 1996 to December 1998, CTAP and CTHA were performed in 12patients with MLC, which were not detect ed byconventional CT examinations. After CTHA, 3 mL-- 5 mL mixture of lipiodol, doxorubic in andmitomycin C were injected into hepatic arterythrough the catheter, and then followed up by CTthree or four weeks later (Lipiodol CT LP-CT).RESULTS A total of 22 micro--tumors (0 .2 cm 0.6 cm in diameter ) were detected in 12patients, which manifested as small perfusiondefects in CTAP and small round enhancement inCTHA. The rate of detectability of CTAP andCTHA was 68.2% (15/ 22) and 77.3% (17/ 22)respectively, and the rate of the simultaneoususe of both procedures reached 86. 4% (19/ 22 ).All micro--tumors were demonstrated as punctatelipiodol deposit fool in LP--CT. After LP--CT, theelevated serum level of Q-fetoprotein (AFP)dropped to the normal level in all patients.CONCLUSION The CTAP and CTHA are the mostsensitive imaging methods for detecting microIiver cancer. Confirmed by the change of theelevated serum AFP level and lipiodol depositfool in LP-CT, small perfusion defects in CTAPand punctate enhancement in CTHA may suggestmicro--liver cancer.
