Quantitative Analysis of Perfusion Characteristics Using Contrast-Enhanced Ultrasound in Patients with Choroidal Metastasis.

ABSTRACT:

Purpose

The aim of the study was to quantitatively analyze the perfusion characteristics of choroidal metastasis using contrast-enhanced ultrasound (CEUS) and compare its perfusion characteristics with these of choroidal hemangioma and choroidal melanoma.

Methods

The patients who were clinically diagnosed with choroidal metastasis were classified as the study group, and the patients who were diagnosed with choroidal hemangioma and choroidal melanoma during the same period were classified as the comparison group. All patients underwent CEUS 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).
