To analyze the application significance of ultrasound contrast agent in identification and diagnosis of ocular spaceoccupying lesions, and mainly analyze its advantages and problems.
Thirty-two representative literatures about the application of ultrasound contrast agent in diagnosis of spaceoccupying lesions at home and abroad were collected after focused on sorting the literature reporting the application of ultrasound contrast diagnostic technology in the diagnosis and identification of ocular spaceoccupying lesions in recent years. Its advantages and problems were retrospectively analyzed, and reasonable assessment on existing problems was made and possible solutions to the problems were proposed.
As a new imaging diagnostic technique, the contrast-enhanced ultrasound, which can enhance the display of tumor microcirculation vessels and improve the tumor's ultrasound diagnostic capability, was analyzed. Through sorting and comprehensively analyzing the collected literatures, the positive rate of ocular spaceoccupying lesion diagnosis could be significantly improved with ultrasound contrast technology. Thus, the vascular perfusion in normal tissues and lesions was reflected objectively. According to the lesion's perfusion characteristics of the contrast agent plus with the performance features of two-dimensional ultrasound, the ocular spaceoccupying lesions can be accurately diagnosed, and this could provide clinicians with reliable research basis in this field.
Ultrasound contrast examination is a new testing method, and ultrasound contrast agent can significantly enhance the ultrasonic detection signal, clearly show the blood perfusion in vessels and tissues, increase the image contrast resolution, and improve the lesion's detection capability in the microcirculation perfusion level, especially its important value in the diagnosis of ocular tumor.
分析超声造影剂在眼部占位性病变鉴别诊断中的应用意义，重点分析其优势及存在的问题。
聚焦近年来报道超声诊断技术在眼部占位性病变诊断及鉴别诊断中应用的文献，收集国内外32篇关于超声造影剂在占位性病变诊断中应用的代表性文献。对其优势及问题进行回顾性分析，对存在的问题作出合理评估并提出可能的解决办法。
分析了超声造影这一可增强肿瘤微循环血管显示、提高肿瘤超声诊断能力的新型成像诊断技术。通过对收集的文献进行整理和综合分析，超声造影技术可显著提高眼部占位性病变的诊断阳性率，客观反映正常组织及病变内的血管灌注情况。根据造影剂的病变灌注特征并结合二维超声的表现特点，可准确诊断眼部占位性病变，为临床医生在该领域提供可靠的研究依据。
超声造影检查是一种新型检查方法，超声造影剂可显著增强超声检测信号，清晰显示血管及组织内的血流灌注情况，提高图像对比分辨率，提升在微循环灌注水平对病变的检测能力，尤其在眼部肿瘤诊断中具有重要价值。
