Purpose : The liver one of the most common site for distant metastasis for a variety of tumor, especially of gastrointestinal
origin. the purpose of this study was to analyze image quality between standard scan and additional liver scan.
Materials and Methods : From September 2015 to February 2016. 152 patients were examined undergo gastrointestinal cancer. 32 patients confirmed liver metastasis analyzed same liver ROI level and check the SNR, SUV and T/N ratio
Results : The SNRmean of standard was 17.7±10.3; addition was 22.3±9.7 (p<0.05). In SUVmax of standard was 6.7±2.8;
addition was 7.6±3.2 (P<0.05). and the T/N ratio of standard was 2.1±0.6; addition was 2.5±0.8 (P<0.05).
Conclusion : The SNRmean, SUVmax and T/N ratio were higher than those on the first scan (P<0.05). The SNRmean showed the highest change rate among the parameters. A additional liver scan is more favorable for the detection of gastrointestinal cancer patients.
