Skull X-rays after trauma: are both laterals necessary?

Eighty-eight sets of skull X-rays, each showing an unequivocal skull fracture, were examined by a radiologist under controlled conditions to see if fractures would be missed if only one lateral view was included in the X-ray series. The fracture sets were mixed at random with four times as many normal sets of skull X-rays and each fracture set was examined on two occasions, once with one latera...

Skull X-rays after mild head injuries.

Can we abolish skull x rays for head injury?

OBJECTIVES To assess the effect of a change in skull x ray policy on the rate of admission, use of computed tomography (CT), radiation dose per head injury, and detection of intracranial injuries; and to compare the characteristics of patients with normal and abnormal head CT.
