Level C recommendations. Given the concern over exposing children to ionizing radiation, consider using ultrasound as the initial imaging modality. In cases in which the diagnosis remains uncertain after ultrasound, CT may be performed.

怀疑儿童阑尾炎用CT也是因为怕被告。 很悲哀的原因。 非常同情ER的医师们。

Despite the advent of computed tomography (CT), appendicitis remains a high-frequency malpractice risk for emergency physicians. Appendicitis is the second most common cause of malpractice litigation in children 6 to 17 years old. Even in the hands of the most experienced clinicians, accurately diagnosing appendicitis can be challenging.

儿外，儿肿瘤科有很多希望能不用就不用CT的鼓吹者。 他们认为瘦瘦的成人怀疑阑尾炎先用B超效果也应不错。 国人符合标准的应该不少。可惜美国没有人做。这些都不是我的原创， 只是追随者而已：】。
