Journal ArticleDOI
DAGAN: Deep De-Aliasing Generative Adversarial Networks for Fast Compressed Sensing MRI Reconstruction
Guang Yang,Simiao Yu,Hao Dong,Greg Slabaugh,Pier Luigi Dragotti,Xujiong Ye,Fangde Liu,Simon R. Arridge,Jennifer Keegan,Yike Guo,David N. Firmin +10 more
TL;DR: This paper provides a deep learning-based strategy for reconstruction of CS-MRI, and bridges a substantial gap between conventional non-learning methods working only on data from a single image, and prior knowledge from large training data sets.
Journal ArticleDOI
Applications of phase-contrast flow and velocity imaging in cardiovascular MRI.
Peter D. Gatehouse,Jennifer Keegan,Lindsey A. Crowe,Sharmeen Masood,Raad H. Mohiaddin,Karl-Friedrich Kreitner,David N. Firmin +6 more
TL;DR: The review includes phase-contrast applications in cardiac function, heart valves, congenital heart diseases, major blood vessels, coronary arteries and myocardial wall velocity.
Journal ArticleDOI
Circadian variation of total ischaemic burden and its alteration with anti-anginal agents
David Mulcahy,David Cunningham,Peter A Crean,Christine E. Wright,Jennifer Keegan,Arshed A. Quyyumi,Amanda Park,Kim Fox +7 more
TL;DR: This circadian distribution of ischaemic episodes and the observed changes with treatment resemble the reported circadian variation of acute myocardial infarction and sudden death.
Journal ArticleDOI

TL;DR: This work presents the methodologies and evaluation results for the WHS algorithms selected from the submissions to the Multi-Modality Whole Heart Segmentation (MM-WHS) challenge, in conjunction with MICCAI 2017.
Journal ArticleDOI
Coronary Artery Imaging in Grown Up Congenital Heart Disease Complementary Role of Magnetic Resonance and X-Ray Coronary Angiography
Andrew M. Taylor,Sara Thorne,Michael B. Rubens,Permi Jhooti,Jennifer Keegan,Peter D. Gatehouse,Frank Wiesmann,Frank Grothues,Jane Somerville,Dudley J. Pennell +9 more
TL;DR: For the assessment of anomalous coronary artery anatomy in patients with congenital heart disease, the use of the combination of MRCA with x-ray coronary angiography improves the definition of the proximal coronary artery course.
