Recent advances in fast MRI may allow timely assessment and a reduced need for head and neck CTA in select populations. MATERIALS AND METHODS: We identified inpatients or patients in the emergency department who
Luminal imaging approaches, such as computed tomographic angiography (CTA) and magnetic resonance angiography (MRA), are routinely used for the diagnosis of ICAD by detecting arterial lumen steno- sis and evaluating stenotic severity. However, high-risk atherosclerotic lesions may present with a large...
摘要 目的: 比较磁共振血管成像(MRA)与颈部血管彩色超声(简称“彩超”)对脑梗死患者颈部血管检查的结果.方法: 将290例核磁共振影像(MRI)或CT证实有脑梗死的患者,分别进行MRA、颈部血管彩超、数字减影血管造影(DSA)检查,并以DSA诊断结果为金标准,比较MRA、颈部血管彩超结果的
Head and neck: CPT codes covered if selection criteria are met: 70544 Magnetic resonance angiography, head; without contrast material(s) 70545 with contrast material(s) 70546 without contrast material(s), followed by contrast material(s) and further sequences 70547 Magnetic resonance angiography, ne...
都是DSA 无法比拟的 近年来 CTA CE-MRA 已广泛应用 由于 3D CEMRA 具有简便、安全、无创等特点,可作为一种重要的辅助检查手段 参考文献: [1]陆建平,刘崎.三维增强磁共振血管成像[M].第 1 版.上海:上海科学技术, 2005,1-8. [2]Hankey GJ, Warlow CP Sellar RJ. Cerebral angiographic risk in mild ce...

For example, to make a surgical plan for head operation, the surgeons should gain more detailed information from CT angiography (CTA) and MR angiography (MRA) images. And the abnormalities can be easily detected from the fusion image which is obtained from two different modalities. One of the...
Methods We compared the characteristics, technical and clinical outcomes of AIS patients undergoing MT with CT head alone (due to variable reasons for CTA/MAR unavailability) versus patients with CT plus CTA or MRA from the ANGEL-ACT registry. ANGEL-ACT is a nationwide prospective registry of ...
