The clinical usefulness of orbital and facial Time-Resolved Imaging of Contrast KineticS (TRICKS) MRI was assessed quantitatively and qualitatively.
A retrospective chart review of the years 2001 to 2011 was conducted at the University of Wisconsin, Madison. Patients were selected based on tumor location (extracranial head and neck) and evaluation with TRICKS imaging at any stage of the clinical course. The TRICKS protocol presented in this article allows measurement of specific tumor characteristics including lesion morphology, vascular anatomy, flow dynamics within the lesion, rapidity and sequential nature of contrast enhancement, and lesion distensibility. Cases involving changes in diagnoses and/or management as a result of TRICKS interpretation are presented in detail.
The imaging records of 49 patients were reviewed. Most lesions were located in or around the orbit (32 lesions, 65%). Benign vascular tumors comprised the largest subcategory (32 lesions, 65%) in the cohort. Of the 20 cases with histopathological data, interpretation of MRI with TRICKS magnetic resonance angiography successfully predicted 17 (85%). Characteristic enhancement patterns for the most commonly encountered lesions are presented, in addition to a qualitative analysis of how TRICKS contributed to select cases. TRICKS helped clarify diagnosis and/or redirect management in 19 of the 49 cases in this series.
To the best of the authors' knowledge, this is the largest study to date of patients evaluated with TRICKS MRI/magnetic resonance angiography for orbital and facial tumors. MRI with TRICKS magnetic resonance angiography imaging protocol offers a minimally invasive, safe, and effective diagnostic instrument in selected patients with clinical diagnostic uncertainty and in those patients requiring high-resolution vascular mapping for management planning.
评估眼眶和面部时分辨力对比剂动力学成像（TRICKS）MRI 的临床应用价值，包括定量和定性评估。
在威斯康星大学麦迪逊分校进行了一项回顾性病历研究，研究时间为 2001 年至 2011 年。入选患者的标准为肿瘤位置（颅外头颈部），且在临床病程的任何阶段均接受过 TRICKS 成像检查。本文介绍的 TRICKS 方案可测量特定的肿瘤特征，包括病变形态、血管解剖结构、病变内的血流动力学、对比增强的快速性和顺序性以及病变的可扩展性。本文详细介绍了因 TRICKS 解读而导致诊断和/或治疗改变的病例。
共回顾了 49 例患者的影像学记录。大多数病变位于眼眶内或周围（32 个病变，占 65%）。良性血管肿瘤是该队列中最大的亚组（32 个病变，占 65%）。在有组织病理学数据的 20 例病例中，TRICKS 磁共振血管造影的解读成功预测了 17 例（85%）。本文还介绍了最常见病变的特征性增强模式，并对 TRICKS 在某些病例中的应用进行了定性分析。在本系列的 49 例病例中，TRICKS 有助于澄清诊断和/或改变管理的病例有 19 例。
据作者所知，这是迄今为止评估眼眶和面部肿瘤患者接受 TRICKS MRI/磁共振血管造影检查的最大研究。TRICKS 磁共振血管造影成像方案为具有临床诊断不确定性的选定患者以及需要高分辨率血管测绘以进行管理计划的患者提供了一种微创、安全、有效的诊断工具。
