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.
