Neuroimaging is an invaluable diagnostic tool for sorting through the vast array of etiologies that underlie altered mental status (AMS). Head computed tomography (CT) without contrast is the primary modality for evaluation of AMS and should be complemented by MR imaging in cases of negative CT but high clinical concern. Studies to maximize brain imaging efficiency and improve the yield of positive scans through the utilization of clinical and laboratory pre-scan diagnostics are ongoing. However, imaging remains the gold standard due to its rapidity with which certain diagnoses can be made or excluded.
神经影像学是一种非常宝贵的诊断工具，可用于梳理导致精神状态改变（AMS）的众多病因。无对比剂的头部计算机断层扫描（CT）是评估AMS的主要方式，在CT结果为阴性但临床高度怀疑的情况下，应辅以磁共振成像（MR）。目前正在进行相关研究，旨在通过利用临床和实验室扫描前诊断来最大化脑成像效率并提高阳性扫描的检出率。然而，由于成像能够快速做出某些诊断或排除某些诊断，它仍然是金标准。
