近年来由于采用了一些新的诊断技术,对于过去需手术探查才能确诊的胰腺疾患的术前确诊率达95％左右,本文扼要介绍胰腺疾患的放射诊断方法及其序贯检查。胰腺扫描用硒~(75)标记的蛋氨酸作胰扫描造影,可作为了解胰腺有无异常的一种非侵入性过筛试验。其主要用途是检查中背部和上腹部疼痛的病人。硒~(75)—蛋氨酸可很快地贮积在胰腺内并与其消化酶类结合,静脉注射30分钟后胰内浓度已可得到满意的显影。任何破坏胰腺实质或干扰胰腺蛋白质合成的疾患,特别是胰腺管阻塞的疾病,都可使胰腺的放射性吸收减低。占位病变(如新生物和假性囊肿)和胰腺炎均
In recent years, due to the use of new diagnostic techniques, the preoperative diagnosis rate for pancreatic diseases that can be diagnosed in the past by surgical exploration has reached about 95%. This article will briefly introduce the diagnostic methods of pancreatic diseases and their sequential examination. Pancreas scans were performed with selenium-(75)-labeled methionine for pancreatic angiography, which can be used as a non-invasive screening test to understand whether the pancreas has abnormalities. Its main purpose is to examine patients with pain in the mid-dorsal and upper abdomen. Selenium-(75)-methionine can be rapidly stored in the pancreas and combined with its digestive enzymes. After 30 minutes of intravenous injection, the concentration in the pancreas can be satisfactorily developed. Any disease that disrupts pancreatic parenchyma or interferes with pancreas protein synthesis, especially in obstructed pancreatic ducts, can reduce the radioactivity absorption of the pancreas. Occupational lesions (such as neoplasms and pseudocysts) and pancreatitis are
