Abstract：
The accurate measurement of splenic size is essential for the diagnosis and management of various gastrointestinal and hematological conditions. While ultrasound (US) and computed tomography (CT) are widely used imaging modalities for assessing splenic size, discrepancies between their measurements have been observed in clinical practice. This study aimed to analyze the measurement differences between US and CT and identify factors influencing these differences. A retrospective analysis of 598 asymptomatic patients who underwent both abdominal US and CT was conducted. Measurements of splenic size obtained from US, axial CT, and coronal CT scans were compared, and various factors such as patient demographics, operator experience, and imaging parameters were evaluated to elucidate their impact on the measurement discrepancies. The results revealed that US consistently underestimated splenic size compared to CT. The magnitude of the discrepancy was influenced by factors such as patient age, body mass index (BMI), depth of the spleen from skin on US and that on CT, visibility of the splenic hilum on US, sonic window quality, and operator experience. This study underscores the importance of considering these factors when interpreting splenic measurements obtained from different imaging modalities in clinical practice.
摘要：
脾脏大小的准确测量对于各种胃肠道和血液学状况的诊断和管理至关重要。虽然超声（US）和计算机断层扫描（CT）被广泛用于评估脾大小的成像模式，在临床实践中观察到他们的测量结果之间的差异。本研究旨在分析US和CT之间的测量差异，并确定影响这些差异的因素。对598例同时接受腹部超声和CT检查的无症状患者进行了回顾性分析。从美国获得的脾大小的测量，轴向CT,和冠状CT扫描进行了比较，和各种因素，如患者的人口统计学，操作员经验，和成像参数进行了评估,以阐明其对测量差异的影响.结果表明，与CT相比，US始终低估了脾大小。差异的大小受到患者年龄等因素的影响，体重指数（BMI），美国和CT上的脾脏与皮肤的深度，脾门在美国的能见度，声音窗口质量，和操作员经验。这项研究强调了在临床实践中解释从不同成像方式获得的脾测量结果时考虑这些因素的重要性。
