RESUMEN
Objective To evaluate the clinical applied value of spiral CT during arterial portography(SCTAP)in evaluating the surgical resectabitity of the hepatocellular carcinoma(HCC).Methods 23 patients with focal hepatic lesions (including HCC 21 cases) were examed with SCTAP,convenient CT and DSA.The difference and the sensitivity in detecting the number of lesions by these three examied methods were comparatively analysed.Results SCTAP had significant difference in comparision with convenient CT and DSA (?0.05) when the lesions were more than 30.0 mm in diameter.21 cases of HCC hepatic metastatic lesions were not found by SCTAP in 9 cases,they chosen the surgical treatment,and 12 cases underwent the interventional trans-catheter artenial chamical embolism(TACE),because of hepatic metastasis showed by SCTAP.Conclusion SCTAP is of high sensitivity in showing small hepatocellular carcinoma and small liver metastatic lesion in comparision with convenient CT and DSA,and it is of great clinical applied value in judging the patients with HCC whether can be or not be treated by surgery.
RESUMEN
5 0 cm, intratumoral necrosis, liquefaction, cystic degeneration, lymph nodes metastases, invasion of renal vein or inferior vena cava, invasion of adjacent organs or distant metastases had higher DNA content Those tumors had higher malignant biological behavior
