ABSTRACT
<p><b>OBJECTIVE</b>To compare the diagnostic value of (18)F-FDG PET-CT with abdomen contrast CT in the diagnosis of peritoneal metastases.</p><p><b>METHODS</b>Between January 2008 and May 2011, imaging results of 97 patients with suspicious peritoneal metastases were retrospectively reviewed, and all the patients underwent both abdomen contrast CT and (18)F-FDG PET-CT imaging. Final diagnosis was made by histopathology or follow up.</p><p><b>RESULTS</b>Seventy-seven patients were verified as peritoneal metastases after pathological examination(n=88) or follow up(n=9), while the other 20 patients were absent. The sensitivity of (18)F-FDG PET-CT was 90.9%(70/77), the specificity 85.0%(17/20), and the accuracy 89.7%(87/97). There were 3 false positive and 7 false negative. The sensitivity of contrast CT was 66.2%(51/77), the specificity 80.0%(16/20), and the accuracy 69.1%(67/97). There were 4 false positive and 26 false negative. The difference in diagnostic accuracy was statistically significantly between these two methods(P<0.05).</p><p><b>CONCLUSION</b>The diagnostic value of (18)F-FDG PET-CT is significantly higher than that of abdominal enhanced CT for peritoneal metastases.</p>
