近年来胰腺肿瘤的发病率有上升趋势,对胰腺肿瘤的早期诊断、对阻塞性黄疸阻塞部位的鉴别、确定或除外胰腺病变,应用超声实时灰阶显像是一项简便易行的探测方法。 一、超声探测胰腺的进展 应用超声图像诊断胰腺疾患是近年来才受到临床的重视。Holm在1969年应用直接接触复合扫描获得了胰腺图像。但是由于胰腺前方为含有气体 In recent years, the incidence of pancreatic tumors has increased. For the early diagnosis of pancreatic tumors, identification of obstructive jaundice obstruction sites, identification or exclusion of pancreatic lesions, the application of ultrasound real-time gray-scale imaging is a simple and easy detection method. First, the progress of ultrasound detection of the pancreas The use of ultrasound imaging to diagnose pancreatic disorders in recent years has only been clinical attention. Holm obtained a pancreas image in 1969 with a direct-contact composite scan. But because of the gas in front of the pancreas
