Planning

Choice of modality

CT of the head in trauma, without IV contrast, is the first choice of investigation.

Settings

Processed images should include thin slices in order to evaluate any skeletal damage.

Indications

In adults, indications mainly include altered mental status, post-traumatic seizure, focal neurologic deficit, vomiting and/or anticoagulant medication.[1] There are various scoring systems for the decision (NICE (UK), NOC (US), [https://jamanetwork.com/journals/jama/fullarticle/201596 CCHR (Canadian)), but for the radiologist it is extremely rare to deny a CT if suggested by a clinician, since it is generally a non-contrast and relatively low dose investigation that is analysed relatively fast.
