常规超声及弹性成像在大网膜疾病中的应用现状

大网膜是人体内最大的腹膜皱襞，常被其他部位病变所累及，其临床表现缺乏特异性，明确诊断有助于临床制定下一步的诊疗计划。超声作为一种简便、无创、有效的检查方法，可作为大网膜病变的首选影像学检查手段。随着超声弹性成像技术的应用，其在术前对大网膜病变良恶性的诊断有较高的敏感性和特异性。大网膜病变确诊依赖病理检查，而超声引导下大网膜穿刺活检是一种创伤小且有效率高的取材方法，可作为获取病理组织的首选方法。本文对常规超声及弹性成像在大网膜疾病中的应用现状进行综述。

Application status of conventional ultrasound and elastography in omental diseases

The Omentum is the largest peritoneal fold in human body, often involved by other parts disease, its clinical manifestations lack of specificity, a clear diagnosis is helpful to make the next diagnosis and treatment plan. As a simple, noninvasive and effective method, ultrasound can be used as the first choice of imaging examination for omental lesions. With the application of ultrasonic elastography, it has higher sensitivity and specificity in the preoperative diagnosis of omental lesions.The definite diagnosis of omental disease depends on pathological examination. Ultrasound guided biopsy of omentum is a minimally invasive and efficient method for obtaining specimens, which can be used as the first choice for obtaining pathological tissues. This paper reviews the application of conventional ultrasound and elastography in omental diseases.
