本研究的目的是建立一个简单的和可重复的超声方法在不同年龄的正常脾脏大小的指南。 230例患者，从新生儿到20岁，因为与脾脏无关的腹部和/或盆腔问题进行超声检查。 所有病例的肝脏和肾脏超声检查结果均正常。 当患者安静呼吸时，通过获得包括脾门在内的冠状面来测量脾脏大小。 测量脾脏顶部和尖端之间的最大纵向距离（脾脏长度），并与年龄、身高和体重相关。 基于这种简单、易用、一次性测量技术，提出了以下关于正常脾脏长度上限的指导原则：3个月时脾脏长度不超过6.0 cm，6个月时不超过6.5 cm，12个月时不超过7.0 cm，2年时不超过8.0 cm，4年时不超过9.0 cm，6年时不超过9.5 cm，8年时不超过10.0 cm，10岁时为11.0 cm，12岁时为11.5 cm，15岁或以上女孩为12.0 cm，15岁或以上男孩为13.0 cm。 随机选择22例已知脾脏异常的患者，并将其脾脏长度与建议的指南进行比较;在每种情况下，脾脏的长度都超过了该年龄的正常上限。在冠状面上测量脾门处从圆顶到尖端的脾脏最大纵向直径的一次测量的正常值，从新生儿到20岁的患者。
The purpose of this study was to establish guidelines for normal splenic size at different ages by using a simple and reproducible sonographic method. Two hundred thirty patients, from neonate to 20-year-old, had sonography because of abdominal and/or pelvic problems unrelated to the spleen. Findings on sonograms of the liver and kidneys were normal in all cases. Splenic size was measured by obtaining a coronal view that included the hilum, while the patient was breathing quietly. The greatest longitudinal distance between the dome of the spleen and the tip (splenic length) was measured and correlated with age, height, and weight. The following guidelines are proposed for the upper limit of normal splenic length based on this simple, easy to use, one-measurement technique: splenic length no greater than 6.0 cm at 3 months, 6.5 cm at 6 months, and 7.0 cm at 12 months, 8.0 cm at 2 years, 9.0 cm at 4 years, 9.5 cm at 6 years, 10.0 cm at 8 years, 11.0 cm at 10 years, 11.5 cm at 12 years, 12.0 cm at 15 years or older for girls, and 13.0 cm at 15 years or older for boys. Twenty-two patients with known abnormalities of the spleen were randomly selected and their splenic lengths compared with the proposed guidelines; in each case, the length of the spleen exceeded the upper limit of normal for that age.Normal values of a single measurement of the greatest longitudinal diameter of the spleen, from the dome to the tip measured at the hilum in the coronal plane, were obtained in patients from newborn to 20 years old.
