RESUMO
Objective To compare diagnostic value of ~(18)F-fluoredeoxyglucose (FDG) PET/CT with contrast-enhanced CT in detecting primary hepatic carcinoma and postoperative recurrence.Methods Twenty-five cases of primary hepatic carcinoma or postoperative recurrent tumor underwent whole-body ~(18)F-FDG PET/CT and contrast-enhanced CT within one week's interval.They were retrospectively reviewed and the difierences between these two modalities were investigated.Results Of these 25 cases,there were 13 cases with primary hepatocellular carcinoma.1 case with intrahepatic cholangiocarcinoma and 11 cases with postoperative recurrence.The sensitivity of 18 F-FDG PET/CT and contrast-enhanced CT in diagnosing primary hepatic carcinoma was 78.6%(11/14) and 92.9%(13/14),and sensitivity in diagnosing postoperative recurrent was 100.0%(11/11) and 63.6%(7/11) respectively.Conclusion Contrast-enhanced CT may have a slight advantage over PET/CT in detecting primary hepatic carcinoma,but ~(18)F-FDG PET/CT combined with contrast-enhanced CT has even greater accuracy.Meanwhile,~(18)F-FDG PET/CT has better diagnostic accuracy in detection of postoperative recurrent tumor.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the influence of Chinese drug Dahuang Zhechong pill on the hepatocellular function.</p><p><b>METHOD</b>Thirty-seven patients with hepatocirrhosis and twelve normal controls were performed the hepatobiliary scintgraphy with Tc-99m labeled ethylene hepatobiliary iminodiacetic acid (99 mTc-EHIDA), and the biochemical examination of hepatic function. There was 19 cases repeated the imaging after 6 months treated with chineses drug. By the three compartmental model configurations, the function parameters of hepatocellular extraction and excretion were calculated.</p><p><b>RESULT</b>In the hepatocirrhosis groups, the hepatocellular uptake peak time and mean residence index were higher than those in normal controls (P < 0.01). Compared to normal controls, the uptake index, uptake speed index and descendent speed index were decreased markedly (P < 0.05). After treatment for 6 months with Chinese drug, the level of serum transaminase, globulin and bilirubin was lower than that before treatment. The uptake peak time and mean residence index decreased notably after treatment for 6 months (P < 0.01), and the uptake index increased, (P < 0.05).</p><p><b>CONCLUSION</b>Chinese drug Dahuang Zhechong pill may improve the hepatocellular function and liver function status in patients with hepatocirrhosis.</p>
