Radiology:CTA作为后起之秀,斩杀颅内小动脉瘤于无形之利器!

随着影像学技术的发展,数字减影血管造影(DSA)仍然作为诊断大部分脑血管病变的金标准,而CT血管造影(CTA)在诊断颅内小动脉瘤方面发挥着越来越大的作用。研究人员通过进行了该项大样本队列研究,旨在以DSA为金标准,评估CTA血管造影在诊断5mm以下的脑动脉瘤的准确性。并将研究结果发表于放射学权威杂志Radiology上。

随着影像学技术的发展,数字减影血管造影(DSA)仍然作为诊断大部分脑血管病变的金标准,而CT血管造影(CTA)在诊断颅内小动脉瘤方面发挥着越来越大的作用。研究人员通过进行了该项大样本队列研究,旨在以DSA为金标准,评估CTA血管造影在诊断5mm以下的脑动脉瘤的准确性。并将研究结果发表于放射学权威杂志Radiology上。该回顾性研究共纳入1366例接受DSA检查并行脑CT血管造影的患者。由两名阅片者对每一位患者的每一个动脉瘤在CTA上的成像特征进行评价,包括动脉瘤的大小、位置和有无破裂。 采用χ2检验比较CTA诊断不同大小、位置和破裂状态动脉瘤的价值。 一致性检验被用于评估阅片者见诊断动脉瘤的一致性。在1366例患者中,DSA上共检出579例患者中有711小动脉瘤。以DSA作为金标准,两名阅片者利用CTA检出小动脉瘤的灵敏度,特异性和准确度分别为97.1%(562/579例)和97.4%(564/579例)、98.5%(451/458例)和99.1%(454/458例)、97.7%(1013/1037例)和98.2%(1018/1037例),这是以每位患者为一例;当以每个动脉瘤为单位时

糖尿病下肢动脉病变影像技术“比拼”

医学论坛网  准确、完整的血管解剖学影像是制定糖尿病下肢动脉病变血管介入治疗或外科手术计划所必需的临床资料,也是手术成功的关键。数字减影血管造影(DSA)、磁共振血管造影(MRA)和CT血管造影(CTA) 三种检查方法根据各自成像原理、患者临床表现和合并症不同而各有利弊,在选择某种方法时应综合考虑患者全身情况。完美的血管成像不仅在于获得高分辨率的影像图片,重要的是为临床治疗提供必需的解

早期诊断糖尿病冠脉病变——选择CAG还是CTA

    糖尿病(DM)患者冠心病的发病率是普通人群的2~4倍,而且与非DM冠心病患者相比,冠状动脉(冠脉)病变弥漫程度高、主干狭窄程度重、受累血管数量多、动脉粥样硬化(AS)病变分布弥漫,双支病变、三支病变和复杂病变、左主干病变以及冠脉斑块溃疡和血栓形成的发生率高(图1),大约15%的DM患者会发生无症状性心肌缺血,主要由于DM自主神经病变,导致患者痛阈升高,胸痛症状不典型,所以准确客

Lancet Neurol:CTA上的斑点征可以预测ICH血肿扩大

背景:脑出血(ICH)早期血肿扩大程度严重影响患者临床预后。止血治疗可以减少血肿扩大,但却未能改善许多患者的临床预后。能否准确分辨血肿扩大的高危患者成为改善预后的关键。本研究为了证明CT血管造影(CTA)能否预测血肿扩大。方法:这项名为PREDICT(使用对比bolus CT预测脑出血血肿的扩大)的研究是一项多中心的前瞻性观察队列研究。研究者招募了年龄在18岁(含)以上的ICH病人,脑出血量小于1

NEJM:CTA检查不能改善冠脉疾病(CAD)治疗效果

背景:很多病人发生冠心病(CAD)之前会出现先兆症状,尽管通过随机试验得出诊断的数据很少,但大家普遍通过使用诊断性操作判断评估患者病情。方式:我们随机选取10003位出现冠心病先兆症状的患者接受冠状动脉CT血管造影(CTA)(我们称之为实验组)或功能性测试(使用运动心电图、核压力测试、负荷超声心动图)(我们称之为对照组)进行试验。我们关注的主要指标是患者死亡率、心肌梗塞和因不稳定性心绞痛住院、出现
