PURPOSE OF REVIEW
To evaluate the utility of magnetic resonance venography with time-resolved imaging (MRV TRI) in the diagnosis of pelvic vein insufficiency (PVI).
RECENT FINDINGS
A retrospective single-center review of N = 17 consecutive patients who underwent pelvic MRI for the assessment of PVI was performed. N = 8/17 (47%) studies were positive for PVI. TRI imaging demonstrated N = 6/8 patients with Grade 0-3 PVI and N = 2/8 patients with May-Thurner Syndrome. N = 4/8 patients underwent elective endovascular management, all of which were technically successful. In the assessment of PVI, MRV TRI provides a dynamic assessment of venous insufficiency, serving as an adjunct to the imaging diagnosis of this pathology.
目的综述
评估时间分辨磁共振静脉成像（MRV TRI）在诊断盆腔静脉功能不全（PVI）中的应用价值。
最近的发现
对 17 例连续因 PVI 评估而行盆腔 MRI 的患者进行回顾性单中心研究。8/17（47%）例研究显示 PVI 阳性。TRI 成像显示 6/8 例 PVI 程度为 0-3 级，2/8 例为 May-Thurner 综合征。8/8 例患者中有 4 例接受了选择性血管内治疗，均取得了技术上的成功。在 PVI 的评估中，MRV TRI 提供了静脉功能不全的动态评估，可作为该病理影像学诊断的辅助手段。
