Computed tomography of the head uses a series of X-rays in a CT scan of the head taken from many different directions; the resulting data is transformed into a series of cross sections of the brain using a computer program. CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well as other conditions involving the skull or sinuses; it used to guide some brain surgery procedures as well. CT scans expose the person getting them to ionizing radiation which has a risk of eventually causing cancer; some people have allergic reactions to contrast agents that are used in some CT procedures.

- Die craniale Computertomographie (CCT) ist eine radiologische Untersuchungsmethode, mit der mittels scheibenartiger Schnittbilder vor allem das Gehirn, aber auch knöcherne Anteile, Gefäße, Gehirnkammern mit Hirnflüssigkeit sowie die übrigen Weichteile im Inneren des Schädels und jeweils viele pathologische Veränderungen dieser Strukturen visualisiert werden können. Es handelt sich dabei um ein bildgebendes Verfahren, das für die moderne Neurologie große Bedeutung hat. (de)
- 头部计算机体层成像（英語：computed tomography of the head）又稱头部电脑断层扫描摄影，是指將一系列從不同方向掃描頭部的X射線獲得的數據經由計算機程序轉為頭部（顱腦）的橫斷面影像的檢查方法。其獲得的橫斷面影像可用於檢查診斷腦損傷和其他神經系統疾病，亦可用於診斷顱骨、鼻竇的情況或作為腦外科手術的引導圖像。不過，CT掃描會使受檢者冒著最終患上癌症的風險暴露在電離輻射下，有些特殊的CT掃描方式使用的造影劑甚至可能使一些人產生過敏反應。 (zh)
