Diagnostic accuracy of Doppler sonography and magnetic resonance venography for the assessmentv of impaired outflow from the internal jugular vein in…

2015

Objectives: This prospective study was aimed at evaluation of diagnostic value of Doppler sonography and magnetic resonance (MR) venography in the internal jugular vein territory. Material and methods: There were assessed 126 patients (252 internal jugular veins). The patients were initially diagnosed using Doppler sonography and MR venography, and then catheter venography of the veins was performed. For the purpose of this study catheter venography was regarded the reference test. We interpreted sonographic findings in the context of criteria proposed by Zamboni and criteria by International Society for Neurovascular Disease (ISNVD). We applied MR protocols aimed at flow assessment in the …
