Sixty-two patients with this hepatic cancer were Included in the study. 56 males and 6 females, with a mean age of 50. 6 yr. (32 - 72 years old). All patients were performed by surgery, verified histologically, and these tumors were smaller than 5 cm. Liver scans were performed 5 minutes, 2 hours and 5 hours after the administration of radlopharmaceutices. In 31 of the 62 patients (50%), the tumor exhibited equal radioactivity uptake or greater radioactivity uptake than the surrounding liver in delayed imaging. And the sensitivity was 33. 3% (2/6), 41.2% (7/17), 60.0% (9/15) and 54.2% (13/24) In the tumor size was ≤2 cm, 2-3cm, 3-4 cm and 4 - 5 cm, respectively. The smallest mass to be detected was only 1. 2 cm. The uptake of radiopharmaceutic was nonsignificantly related to serum AFP level and hepatic cirrhosis (P>0. 05). These results show that 99-Tc-PMT delayed hepatobiliary imaging can be useful in the diagnosis of small hepatocellular carcinoma.展开更多
