The paper presents the differential diagnostic signs of choroidal tumors, which are revealed by spatial ultrasound analysis of their angioarchitectonics. An algorithm of a study of the angioarchitectonics of choroidal tumors has been developed on the basis of the current ultrasound technologies that can combine B- and 3D-mode grey scale with energy and color Doppler mapping. Fifty-six patients (58 eyes) with various choroidal neoplasms, including 42 patients with choroidal melanomas, 6 with circumscribed choroidal hemangiomas, and 8 (10 eyes) with metastatic choroidal lesion, were examined. Analysis of the results of the study revealed the specific echographic features of each type of a tumor. The proposed procedure of ultrasound analysis makes it possible to expand the spectrum of the analyzed parameters of the angioarchitectonics, to locate spatially, and to trace the association of the neoplasmic vascular bed with the extraocular circulatory system, which is of great importance in choosing an adequate treatment option.
本文介绍了脉络膜肿瘤的鉴别诊断体征，这些体征通过对其血管构筑的空间超声分析得以揭示。基于当前可将B型和三维模式灰度与能量及彩色多普勒成像相结合的超声技术，已开发出一种研究脉络膜肿瘤血管构筑的算法。对56例（58只眼）患有各种脉络膜肿瘤的患者进行了检查，其中包括42例脉络膜黑色素瘤患者、6例局限性脉络膜血管瘤患者以及8例（10只眼）脉络膜转移瘤患者。对研究结果的分析揭示了每种肿瘤类型的特定超声特征。所提出的超声分析程序能够扩展血管构筑分析参数的范围，进行空间定位，并追踪肿瘤血管床与眼外循环系统的关联，这对于选择合适的治疗方案非常重要。
