由于广泛的鉴别诊断以及医疗保健提供者普遍使用不充分或不准确的分类系统，血管畸形提出了诊断和治疗挑战。这些病变的治疗方法根据血管异常的类型、大小和范围而有所不同，因此需要准确的诊断和分类。磁共振 (MR) 成像 (MRI) 是一种对血管异常进行分类的有效方式，因为它能够描绘畸形的范围以及与邻近结构的解剖关系。除了解剖映射之外，血管异常的完整评估还包括血流动力学特征。动态时间分辨对比增强磁共振血管造影可提供有关血管异常血流动力学的信息，区分高流量和低流量血管畸形。放射科医生必须识别血管畸形的 MRI 特征，以便更好地诊断和分类。
Vascular malformations pose a diagnostic and therapeutic challenge due to the broad differential diagnosis as well as common utilization of inadequate or inaccurate classification systems among healthcare providers. Therapeutic approaches to these lesions vary based on the type, size, and extent of the vascular anomaly, necessitating accurate diagnosis and classification. Magnetic resonance (MR) imaging (MRI) is an effective modality for classifying vascular anomalies due to its ability to delineate the extent and anatomic relationship of the malformation to adjacent structures. In addition to anatomical mapping, the complete evaluation of vascular anomalies includes hemodynamic characterization. Dynamic time-resolved contrast-enhanced MR angiography provides information regarding hemodynamics of vascular anomalies, differentiating high- and low-flow vascular malformations. Radiologists must identify the MRI features of vascular malformations for better diagnosis and classification.
