Accuracy of unenhanced magnetic resonance angiography for the assessment of renal artery stenosis
European Journal of Radiology Open, 2016 Purpose: To evaluate the accuracy of unenhanced magnetic resonance angiography (U-MRA) using balanced steady-state free precession (SSFP) sequences with inversion recovery (IR) pulses for the evaluation of renal artery stenosis.

Deep Residual Network for Off-Resonance Artifact Correction with Application to Pediatric Body Magnetic Resonance Angiography with 3D Cones [PDF]
arXiv, 2018 Purpose: Off-resonance artifact correction by deep-learning, to facilitate rapid pediatric body imaging with a scan time efficient 3D cones trajectory. Methods: A residual convolutional neural network to correct off-resonance artifacts (Off-ResNet) was trained with a prospective study of 30 pediatric magnetic resonance angiography exams.

A Two-step Surface-based 3D Deep Learning Pipeline for Segmentation of Intracranial Aneurysms [PDF]
arXiv, 2020 The exact shape of intracranial aneurysms is critical in medical diagnosis and surgical planning. While voxel-based deep learning frameworks have been proposed for this segmentation task, their performance remains limited. In this study, we offer a two-step surface-based deep learning pipeline that achieves significantly higher performance.

Designing contrasts for rapid, simultaneous parameter quantification and flow visualization with quantitative transient-state imaging [PDF]
arXiv, 2019 Magnetic resonance imaging (MRI) is a remarkably powerful diagnostic technique: it generates wide-ranging information for the non-invasive study of tissue anatomy and physiology. Complementary data is normally obtained in separate measurements, either as contrast-weighted images, which are fast and simple to acquire, or as quantitative parametric maps,

The filling defect of pulmonary artery, an imaging finding what we should know
Pulmonary Circulation, 2020 The most common cause of pulmonary artery filling defects on computed tomography pulmonary angiography or magnetic resonance imaging is pulmonary thromboembolism, but not infrequently, the presentation of this finding lacks specificity.

Volumetric analysis of arteriovenous malformation using computed tomographic angiography [PDF]
, 2013 Thesis (M.A.)--Boston UniversityAn arteriovenous malformation (AVM) is an abnormal collection of blood vessels in which arterial blood flows directly into the draining vein without the normal interposed capillaries.
