A subcutaneous mouse tumor model and an intraperitoneal ovarian cancer metastasis model were constructed using SKOV3\u2010Luc cells. Near\u2010infrared fluorescence (NIRF) imaging was performed to determine the imaging parameters and evaluate the ability of COC183B2\u2010Cy7 to detect tiny metastatic lesions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>OC183B2 was expressed in metastatic lymph nodes and SKOV3\u2010Luc cells. NIRF imaging of the subcutaneous mouse tumor model showed that the tumor background ratio was significantly higher in the COC183B2\u2010Cy7 group than in the control group at different time points postinjection. Biodistribution study showed that COC183B2\u2010Cy7 did not accumulate in other organs. COC183B2\u2010Cy7 can detect tiny metastatic lesions of ovarian cancer. The smallest intraperitoneal metastatic tumor detected by COC183B2\u2010Cy7 was approximately 1\u2009mm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>COC183B2\u2010Cy7 probe has relatively high specificity and sensitivity.
