The abdomen has been conveniently divided anatomically and clinically into specific intraperitoneal and extraperitoneal sites. A recognition of the pathways of spread and localizing features of infections, malignancies, and traumatic collections has immeasurably extended diagnostic imaging capabilities. Yet, while the abdomen may be visualized as subdivided into compartments, it must also be essentially appreciated that these compartments are an actual or potential interconnecting network. In the upper abdomen peritoneal reflections comprise 11 major ligaments and mesenteries. These are generally readily recognizable on computed tomographic scans by either their typical location and organ relationships or the landmarks provided by their major constituent vessels. These ligaments and mesenteries provide continuity of anatomic planes, which permits the spread of disease between intraperitoneal compartments, between extraperitoneal spaces, and between intraperitoneal and extraperitoneal localized sites.
腹部在解剖学和临床上被方便地划分为特定的腹腔内和腹腔外部位。认识感染、恶性肿瘤和创伤性积液的扩散途径及定位特征，极大地扩展了诊断成像能力。然而，虽然腹部可被视为划分为多个腔隙，但必须切实认识到这些腔隙实际上是一个相互连通的网络，或具有相互连通的可能性。在上腹部，腹膜反折形成11条主要韧带和系膜。通过其典型位置、与器官的关系或其主要组成血管提供的标志，这些结构通常在计算机断层扫描上很容易识别。这些韧带和系膜提供了解剖平面的连续性，使得疾病能够在腹腔内各腔隙之间、腹腔外间隙之间以及腹腔内和腹腔外局部部位之间扩散。
