Abstract：
Background Low back pain (LBP) is common and considerably impacts daily lives across all age groups. MRI is not frequently used as a first-line investigation for patients presenting with LBP, except in the presence of red-flag symptoms. This study aimed to use pain severity and its impact as a predictor for MRI findings to help physicians decide whether a patient needs an MRI. Methods This cross-sectional study was conducted at the outpatient clinic of the neurosurgery department. The questionnaire included demographic data of the patients, red-flag symptoms, and the Dallas Pain Questionnaire (DPQ). The primary physician then determines whether the patient should have an MRI appointment. Results The study included 100 patients with LBP, of which 71 had chronic LBP (CLBP). Out of these 71, an MRI was requested for 62, but only 26 had findings related to LBP. Regarding the impact of CLBP on daily activities as measured by the DPQ, there was a significant association between those whose CLBP affected their daily activities and the decision to request an MRI. However, no significant statistical association was found between the three other parameters of the DPQ and the primary physician\'s decision to request an MRI. Conclusion Concerning the use of the DPQ questionnaire to predict MRI findings in patients with CLBP, the study indicates that significant pain impact on the DPQ does not necessarily correlate with MRI findings related to LBP. This suggests that the DPQ evaluation tool has no advantage over a physician\'s clinical judgment.
摘要：
背景技术腰背痛(LBP)是常见的并且显著影响所有年龄组的日常生活。MRI并不经常用作表现为LBP的患者的一线检查。除了有红旗症状.这项研究旨在使用疼痛严重程度及其影响作为MRI结果的预测指标，以帮助医生确定患者是否需要MRI。方法本横断面研究在神经外科门诊进行。问卷包括患者的人口统计学数据，红旗症状,和达拉斯疼痛问卷(DPQ)。然后，主治医师确定患者是否应该进行MRI预约。结果本研究纳入100例LBP患者,其中71例患有慢性LBP（CLBP）。在这71个中，有62个要求进行MRI检查，但只有26个发现与LBP有关。关于CLBP对DPQ衡量的日常活动的影响，CLBP影响其日常活动的患者与要求进行MRI检查的决定之间存在显著关联.然而,DPQ的其他3个参数与主诊医师要求MRI的决定之间未发现显著的统计学关联.结论关于使用DPQ问卷预测CLBP患者的MRI表现，研究表明,疼痛对DPQ的影响不一定与LBP相关的MRI表现相关.这表明DPQ评估工具没有优于医生的临床判断。
