Iliac vein compression syndrome (IVCS) diagnosis heavily relies on an imaging test. However, non-invasive and contrast-free imaging test for the diagnosis of IVCS remains a big challenge. To address this issue, this prospective study aimed to assess the image quality and diagnostic performance of a magnetic resonance imaging technique, black-blood venous imaging (BBVI), in detecting IVCS by comparing it with contrast-enhanced computed tomography venography (CTV) and using invasive digital subtraction angiography (DSA) as the reference.
We enrolled 105 patients, and all patients underwent BBVI, CTV, and DSA examinations. We compared the consistency of CTV and BBVI image quality and their consistency in diagnosing the rate of iliac vein stenosis in IVCS patients. Using the consensus DSA as a reference, the sensitivity, specificity, positive and negative predictive values, and accuracy of BBVI and CTV and their diagnostic agreement with DSA were calculated.
BBVI demonstrated high sensitivity, specificity, and accuracy for the diagnosis of IVCS, without contrast agents. BBVI and CTV are quite in diagnosis IVCS. Quite SE (67.8% vs 68.3%), SP (94.8% vs 94.8%), PPV (98.0% vs 98.0%), NPV (46.2% vs 46.9%) and ACC (75.3% vs 75.7%) were obtained by BBVI in comparison with CTV.
BBVI has comparable diagnostic performance with CTV. It may be a viable alternative to CTV techniques in screening the IVCS without contrast agents and free of ionizing radiation.
髂静脉压迫综合征（IVCS）的诊断主要依赖于影像学检查。然而，对于 IVCS 的诊断，仍然缺乏一种非侵入性且无需造影的影像学检查方法。为了解决这个问题，本前瞻性研究旨在评估磁共振成像技术——黑血静脉成像（BBVI）在诊断 IVCS 方面的图像质量和诊断性能，通过与对比增强计算机断层静脉造影（CTV）进行比较，并以有创性数字减影血管造影（DSA）作为参考。
我们纳入了 105 例患者，所有患者均接受了 BBVI、CTV 和 DSA 检查。我们比较了 CTV 和 BBVI 图像质量的一致性，以及它们在诊断 IVCS 患者髂静脉狭窄率方面的一致性。使用共识 DSA 作为参考，计算了 BBVI 和 CTV 的敏感性、特异性、阳性预测值、阴性预测值和准确性，以及它们与 DSA 的诊断一致性。
BBVI 显示出对 IVCS 诊断的高敏感性、特异性和准确性，无需造影剂。BBVI 和 CTV 在诊断 IVCS 方面非常一致。BBVI 与 CTV 相比，SE 为 67.8%（67.8%对 68.3%），SP 为 94.8%（94.8%对 94.8%），PPV 为 98.0%（98.0%对 98.0%），NPV 为 46.2%（46.2%对 46.9%），ACC 为 75.3%（75.3%对 75.7%）。
BBVI 与 CTV 具有相当的诊断性能。它可能是一种替代 CTV 技术的可行方法，可用于在无造影剂和无电离辐射的情况下筛查 IVCS。
