Abstract:
AIM:To investigate the application value of contrast-enhanced ultrasound(CEUS)time parameters in the classification diagnosis of choroidal space-occupying lesions.METHODS: Patients with choroidal space-occupying lesions who underwent CEUS at Xi'an People's Hospital(Xi'an Fourth Hospital)between June 2020 and January 2024 were enrolled. According to the final clinical diagnosis and pathological findings, the patients were divided into a benign group(choroidal hemangioma), a malignant group(choroidal melanoma), and a hemorrhage group(subchoroidal hemorrhage). CEUS characteristics and contrast parameters, including rise time(RT), time to peak(TP), and washout time(WT), as well as the incidence of adverse reactions, were analyzed to evaluate the diagnostic value of CEUS.RESULTS:A total of 120 patients(120 eyes)with choroidal space-occupying lesions were included, with 40 patients(40 eyes)in each group. The patients in the benign group were aged 45-70(mean age 57.5±12.4 )y, including 19 males and 21 females; those in the malignant group were aged 43-72(mean age 56.9±13.1 )y, including 23 males and 17 females; and those in the hemorrhage group were aged 40-61(mean age 54.4±9.7 )y, including 22 males and 18 females. The benign group predominantly exhibited homogeneous hyperenhancement with a “fast-in, slow-out”perfusion pattern, whereas the malignant group mainly showed heterogeneous hyperenhancement with a “fast-in, fast-out”perfusion pattern. No obvious enhancement was observed in the hemorrhage group, exhibiting a “no-in, no-out” perfusion pattern. Significant differences were found among the three groups in CEUS characteristics and quantitative parameters, whereas no significant difference was observed in the incidence of adverse reactions.CONCLUSION: CEUS can significantly improve the diagnostic accuracy of choroidal space-occupying lesions and may serve as a useful reference for clinical decision-making, with a favorable safety profile.
