Usefulness of Cervical Computed Tomography Hounsfield Units to Differentiate Kawasaki Disease From a Deep-neck Abscess.

We measured the Hounsfield units (HUs) value of cervical plain computed tomography images to differentiate between Kawasaki disease (KD) and a deep-neck abscess (DNA). The HUs value was significantly lower in KD than in DNA, making it a useful marker for differentiating between these 2 diseases.
