Dear Editor, We appreciate the interest in our publication entitled “Four-dimensional flow MRI for evaluation of post-stenotic turbulent flow in a phantom: comparison with flowmeter and computational fluid dynamics”[1] The authors raised the issues of...
Dear Editor, A recent study by Kweon et al evaluated 4D flow MRI for evaluation post-stenotic turbulent flow and conclude that phase-contrast magnetic resonance imaging (PC-MRI) has limitations in the assessment of turbulent characteristics [1]. Evaluation and...
Dear Editor, Dural arteriovenous fistulas (dAVF) are shunts from meningeal arteries into venous sinuses and/or cortical veins [1]. DAVF can be classified according to their venous drainage pattern based on Cognard et al. and result in a bleeding risk of 40-65 % in the...
Dear Editor, I was interested to read the paper by Djurdjevic T and colleagues published in Eur Radiol 2017 Mar. After intraarterial recanalisation (IAR), haemorrhage and blood-brain barrier (BBB) disruption can be distinguished using dual-energy computed tomography...
Dear Editor, I read with interest the comment of the reader on my study: “I was well aware of this large series including 170 patients, reason why it was included in the discussion section (page 4). There was no mistake in the number of patients (Similar results...
Dear Editor, with interest we read the manuscript “Stent-Retriever Thrombectomy for Acute Anterior Ischemic Stroke with Tandem Occlusion: A Systematic Review and Meta-Analysis” by Sivan-Hoffmann et. al, published in European Radiology. Therein, our Study...
