Abstract
StarVIBE is a 3D gradient-echo sequence with a radial, stack-of-stars acquisition having spatial resolution and tissue contrast. With newer sequences, it is important to be familiar with sequence tissue contrasts and appearance of anatomical variants. We evaluated 450 patients utilizing this sequence; 35 patients demonstrated fluffy "cotton wool" enhancement at the internal auditory canal fundus without clear pathology. We favor this represents anatomic neurovascular enhancement that StarVIBE is sensitive to and is a touch-me-not finding.
摘要
StarVIBE 是一种 3D 梯度回波序列，采用径向、星形采集方式，具有空间分辨率和组织对比度。对于较新的序列，熟悉序列的组织对比度和解剖变异的表现形式很重要。我们使用该序列评估了 450 例患者；35 例患者在内耳道口底部呈现出“棉花状”增强，但无明显病理学改变。我们认为这代表了 StarVIBE 敏感的解剖神经血管增强，是一种触摸不得的发现。
