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.
准确测量脾脏大小对于各种胃肠道和血液系统疾病的诊断和管理至关重要。虽然超声（US）和计算机断层扫描（CT）是评估脾脏大小广泛使用的成像方式，但在临床实践中已观察到它们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例接受腹部US和CT检查的无症状患者进行了回顾性分析。比较了从US、轴向CT和冠状CT扫描获得的脾脏大小测量值，并评估了患者人口统计学、操作者经验和成像参数等各种因素，以阐明它们对测量差异的影响。结果显示，与CT相比，US始终低估脾脏大小。差异的程度受患者年龄、体重指数（BMI）、US和CT上脾脏距皮肤的深度、US上脾门的可见性、声窗质量和操作者经验等因素影响。本研究强调了在临床实践中解释从不同成像方式获得的脾脏测量值时考虑这些因素的重要性。
