目的:探讨时间飞跃法磁共振血管成像(three-dimensional time of flight MRA,3D-TOF-MRA)与CT血管造影(CT angiography,CTA)对未破裂颅内动脉瘤(unruptured intracranial aneurysms,UIAs)的诊断价值。方法:回顾性收集2019年7月—2022年...目的:探讨时间飞跃法磁共振血管成像(three-dimensional time of flight MRA,3D-TOF-MRA)与CT血管造影(CT angiography,CTA)对未破裂颅内动脉瘤(unruptured intracranial aneurysms,UIAs)的诊断价值。方法:回顾性收集2019年7月—2022年6月经数字减影血管造影(digital subtraction angiography,DSA)确诊为UIAs 52例患者的3D-TOF-MRA及CTA图像,比较MRA和CTA对颅内动脉瘤的检出率、瘤体最大径及瘤体颈宽测量结果的差异,MRA和CTA对颅内动脉瘤检出的一致性采用Kappa检验。结果:DSA确诊的52例患者中,共检出动脉瘤63个,MRA及CTA分别检出真实动脉瘤52个及53个,检出率分别为82.54%及84.13%,两者的差异无统计学意义(P>0.05),且两者对颅内动脉瘤的检出具有良好的一致性(Kappa=0.94);MRA与CTA对颅内动脉瘤瘤体最大径及瘤体颈宽测量结果的差异无统计学意义(P>0.05)。结论:3D-TOF-MRA与CTA在UIAs的诊断中均具有较高的价值,但3D-TOF-MRA是一种无电离辐射、无需注射对比剂的无创检查,方便重复检查,故UIAs的筛查和定期随访首选3D-TOF-MRA。展开更多

The 49 questions that comprised the original draft of the UUIACS were created based on interview data. Based on data from 172 participants, exploratory and confirmatory factor analyses were conducted. As a result of exploratory factor analysis, the UUIACS e retained 17 items and extracted four factors (“Lack of decision-making cues”, “Lack of information and complexity of information interpretation”, “The ambiguous nature of the disease”, and “The unpredictable living with UIA”). All of the UUIACS items showed adequate internal consistency. Between the UUIAC scale and the Universal Uncertainty in Illness Scale (UUIS), the Health Locus of Control (HLC) scale, and the SF-36v2® (Japanese version), positive correlations were found between the UUIACS and UUIS, and the HLC scale at a 1% significance level indicating concurrent validity. According to confirmatory factor analysis, the UUIACS had an acceptable goodness of fit. Given these findings, the UUIACS was judged to have satisfied the criteria for use in a clinical setting, although further investigation was required.展开更多
