To evaluate the utilisation of CT diagnostic imaging in patients admitted to hospital with a clinical diagnosis of stroke, and to identify factors which influence the use of CT imaging in stroke. Two hundred and fifty consecutive (155 females) stroke patients were assessed median age 76 years (range 39-95 y). Ninety-seven patients underwent CT scanning; median time to scan from admission was two days (range 0-43). The time to CT scanning was significantly shorter in patients aged < 65 years (p < 0.001), and in patients with a non-disabling stroke (p < 0.05). The factors (odds ratios and 95% confidence limits) significantly associated with CT scanning were male sex (2.21:1.31-3.74); normal Glasgow coma score (2.48:1.59-3.85); Rankin score 1-3 (6.40:1.74-23.56); age < 65 years (10.23:4.49-23.32) and no previous cerebrovascular event (1.97:1.10-3.51). In this study, those patients who would benefit most from medical intervention with antiplatelet agents to reduce the risk of recurrence were more likely to receive CT diagnostic imaging.
为评估临床诊断为中风的住院患者中CT诊断成像的应用情况，并确定影响中风患者CT成像使用的因素。对250例连续的（155例女性）中风患者进行了评估，中位年龄76岁（范围39 - 95岁）。97例患者接受了CT扫描；从入院到扫描的中位时间为两天（范围0 - 43天）。年龄<65岁的患者（p < 0.001）以及非致残性中风患者（p < 0.05）的CT扫描时间明显更短。与CT扫描显著相关的因素（比值比和95%置信区间）为男性（2.21:1.31 - 3.74）；格拉斯哥昏迷评分正常（2.48:1.59 - 3.85）；Rankin评分1 - 3分（6.40:1.74 - 23.56）；年龄<65岁（10.23:4.49 - 23.32）以及既往无脑血管事件（1.97:1.10 - 3.51）。在本研究中，那些最能从使用抗血小板药物进行医学干预以降低复发风险中获益的患者更有可能接受CT诊断成像。
