Journal ArticleDOI
Perfusion-CT Assessment of Infarct Core and Penumbra Receiver Operating Characteristic Curve Analysis in 130 Patients Suspected of Acute Hemispheric Stroke
Max Wintermark,Adam E. Flanders,Birgitta K. Velthuis,Reto Meuli,Maarten S. van Leeuwen,Dorit Goldsher,Carissa Pineda,Joaquín Serena,Irene C. van der Schaaf,A. Waaijer,James C. Anderson,Gary M. Nesbit,Igal Gabriely,Victoria Medina,Ana Quiles,Scott Pohlman,Scott Pohlman,Marcel Quist,Pierre Schnyder,Julien Bogousslavsky,William P. Dillon,Salvador Pedraza,Salvador Pedraza +22 more
TL;DR: In a large series of 130 patients, the optimal approach to define the infarct and the penumbra is a combined approach using 2 PCT parameters: relative MTT and absolute CBV, with dedicated thresholds.
Journal ArticleDOI
Segmentation of multiple sclerosis lesions in brain MRI: A review of automated approaches
Xavier Lladó,Arnau Oliver,Mariano Cabezas,Jordi Freixenet,Joan C. Vilanova,Ana Quiles,Laia Valls,Lluís Ramió-Torrentí,ílex Rovira +8 more
TL;DR: The main features of the segmentation algorithms are analysed and the most recent important techniques are classified into different strategies according to their main principle, pointing out their strengths and weaknesses and suggesting new research directions.
Journal ArticleDOI
Wallerian Degeneration in the Corticospinal Tract Evaluated by Diffusion Tensor Imaging Correlates with Motor Deficit 30 Days after Middle Cerebral Artery Ischemic Stroke
Josep Puig,Salvador Pedraza,Gerard Blasco,Josep Daunis-i-Estadella,A Prats,Ferran Prados,Imma Boada,Mar Castellanos,Javier Sánchez-González,Sebastian Remollo,Gemma Laguillo,Ana Quiles,E. Gómez,J. Serena +13 more
TL;DR: WD in the CST revealed by DTI correlates with motor deficit 30 days after MCA ischemic stroke and the utility of imaging follow-up at 30 days is highlighted and the potential of DTI as a surrogate marker in clinical trials is highlighted.
Journal ArticleDOI
Hemorrhagic stroke lesion segmentation using a 3D U-Net with squeeze-and-excitation blocks.
Valeriia Abramova,Albert Clèrigues,Ana Quiles,Deysi Garcia Figueredo,Yolanda Silva,Salvador Pedraza,Arnau Oliver,Xavier Lladó +7 more
TL;DR: In this article, a 3D U-Net based approach is proposed to automatically segment hemorrhagic stroke lesions in CT scans, which incorporates the recently proposed squeeze-and-excitation blocks.
Journal ArticleDOI
Albumin-binding MR blood pool contrast agent improves diagnostic performance in human brain tumour: comparison of two contrast agents for glioblastoma
Josep Puig,Gerard Blasco,Marco Essig,Josep Daunis-i-Estadella,Gemma Laguillo,Ana Quiles,Sebastian Remollo,Karsten Bergmann,Carme Joly,Lluis Bernado,Javier Sánchez-González,Salvador Pedraza +11 more
TL;DR: Gadobutrol gives significant tumour enhancement in early postcontrast imaging in patients with glioblastoma, but images acquired 6 h after gadofosveset injection have significantly better diagnostic information endpoints and contrast enhancement.
