Abstract:
Objective:To analyze the perfusion characteristics of choroidal metastasis using contrast-enhanced ultrasound, and compare with choroidal hemangioma.Methods:This was a retrospective study.From January 2016 to February 2018 in Beijing Tongren Hospital, a total of 21 eyes from 21 patients who were clinically diagnosed as choroidal metastasis were included as the choroidal metastasis group and 46 eyes from 46 patients who were diagnosed as choroidal hemangioma during the same period were included as the choroidal hemangioma group. All patients underwent contrast-enhanced ultrasound examination, and Sonoliver was used to obtain the data on quantitative parameters of the tumor and the adjacent normal orbital tissues, including maximum of intensity (IMAX), rise time (RT), time to peak (TTP), and mean transit time (mTT). The quantitative parameters between choroidal metastasis and normal orbital tissues were compared. And the quantitative parameters between choroidal metastasis and choroidal hemangioma were compared. The receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance.Results:The IMAX of choroidal metastasis was significantly higher than that of normal orbital tissues, while RT, TTP and mTT were significantly shorter than these of normal orbital tissues (all P<0.01). The IMAX of choroidal metastasis was lower than that of choroidal hemangioma, and RT, TTP and mTT were shorter than choroidal hemangioma (all P<0.01). The ROC curve analysis showed that area under curves of the IMAX, RT, TTP and mTT were 0.775 (95% CI=0.666-0.884), 0.970 (95% CI=0.896-0.996), 0.729 (95% CI=0.607-0.831) and 0.992 (95% CI=0.931-1.000) respectively. The sensitivities were 71.7%, 95.7%, 76.1% and 95.7%, and the specificities were 85.7%, 90.5%, 66.7% and 95.2%, respectively. Conclusions:Contrast-enhanced ultrasound can reflect the differences in perfusion characteristics between choroidal metastasis and choroidal hemangioma. RT and mTT are useful parameters in differential diagnosis between the two types of tumors.
