Synopsis

Keywords: Vessels, Thrombo-EmbolicAbdominal vein thrombosis (AVT) is a significant cause of morbidity. Accurate diagnosis of AVT is relevant for treatment proper decision-making. CTV or MRV requires the use of contrast medium, which may lead to patient's renal failure or allergic reaction. To address this issue, we sought to develop a direct AVT imaging (DATI) technique which is free of contrast medium. The technique is based on a respiratory navigating SPACE sequence with DANTE black-blood preparation and evaluated preliminarily on 19 AVT patients at 3.0T. Experiment results show that DATI can provide definitive thrombus detection for the diagnosis of AVT.
