Brain damage inflicted by head trauma may not be visible on computed tomography or magnetic resonance imaging. This is true not only for mild head trauma, but also for moderate and severe head trauma. Perfusion imaging with single-photon emission computed tomography has proved in several controlled studies to be more sensitive than either computed tomography or magnetic resonance imaging in detecting brain abnormalities in patients with head trauma.
头部创伤造成的脑损伤在计算机断层扫描或磁共振成像上可能并不明显。不仅轻度头部创伤如此，中度和重度头部创伤也是如此。在多项对照研究中已证明，单光子发射计算机断层扫描灌注成像在检测头部创伤患者的脑异常方面比计算机断层扫描或磁共振成像更敏感。
