肝硬化是一种常见的由不同病因引起的慢性进行性弥漫性肝病,随着病情进展,出现门静脉高压,从而形成广泛而复杂的门体侧支循环,在食管胃底静脉曲张破裂出血、肝性脑病的发生和发展中有重要的临床意义。近年来,随着影像技术的发展和各种计算机软件的开发,CT和MRI在临床的应用日益广泛。特别是64层螺旋CT,它结合三维重建等各种后处理技术能获取等于甚至超过许多经典血管造影的图像,从而使其影像评估有了较大进展。近年来国内外许多作者从不同角度进行了研究,现
Cirrhosis is a common chronic diffuse liver disease caused by different causes. With the progression of the disease, portal hypertension occurs, forming extensive and complex collateral circulation. In esophageal and gastric variceal bleeding, liver The occurrence and development of encephalopathy have important clinical significance. In recent years, with the development of imaging technology and the development of various computer softwares, CT and MRI have been widely used in clinical practice. Especially 64-slice spiral CT, which combined with three-dimensional reconstruction and other post-processing techniques to obtain equal to or exceed many of the classic angiography images, making its assessment of the image has made great progress. In recent years, many authors at home and abroad have studied from different angles
