背景：用于颈动脉分叉和其他颈动脉的非增强磁共振血管造影（NEMRA）的标准护理飞行时间（TOF）技术通常由于运动和血流伪影而提供非诊断性图像质量。目的：将非门控径向静止间隔切片选择（QISS）技术用于颈部NEMRA进行初步评估，并与2D TOF和增强磁共振血管造影（CEMRA）进行比较。研究类型回顾性。人群：60例患者行颈部磁共振血管造影。3T时场强/序列非门控径向QISS。3名放射科医生使用4分制对18个动脉段的图像质量进行评分（1，无诊断性；2，一般；3，良好；4，极好），2名放射科医生使用5个类别对近段颈内动脉狭窄进行评分(
Background Standard-of-care time-of-flight (TOF) techniques for nonenhanced magnetic resonance angiography (NEMRA) of the carotid bifurcation and other cervical arteries often provide nondiagnostic image quality due to motion and flow artifacts. Purpose To perform an initial evaluation of an ungated radial quiescent-interval slice-selective (QISS) technique for NEMRA of the neck, in comparison with 2D TOF and contrast-enhanced magnetic resonance angiography (CEMRA). Study Type Retrospective. Population Sixty patients referred for neck MR angiography. Field Strength/Sequence Ungated radial QISS at 3T. Assessment Three radiologists scored image quality of 18 arterial segments using a 4-point scale (1, nondiagnostic; 2, fair; 3, good; 4, excellent), and two radiologists graded proximal internal carotid stenosis using five categories (
