Rapid online deep artifact suppression for real-time spiral bSSFP CMR with blipped-CAIPI simultaneous multi-slice imaging at 1.5 T [0.03%]
基于片段化并行成像的同时多层实时螺旋bSSFP心磁共振快速在线深伪影抑制方法（1.5T）
Julius Åkesson,Iulius Dragonu,Einar Heiberg et al.
Julius Åkesson et al.
Purpose: Real-time (RT) bSSFP MRI enables fast free-breathing cardiovascular imaging but requires 10-16 slices for functional assessment, resulting in prolonged scan times. Simultaneous multi-slice (SMS) imaging can reduc...
A comparative evaluation of multiple enlarged perivascular space segmentation tools [0.03%]
多种扩大的血管周围间隙分割工具的比较评估
James D LeFevre,W Hudson Robb,Dandan Liu et al.
James D LeFevre et al.
Background: Enlarged perivascular spaces (ePVS) are a marker of cerebral small vessel disease, potentially reflecting reduced waste clearance. Because manual quantification is unfeasible in large datasets, we developed an...
Comparison of semi-automatic myocardial scar segmentation methods on black-blood late gadolinium enhancement images [0.03%]
黑血延迟增强磁共振心肌疤痕图像的半自动分割方法比较研究
Thaïs Génisson,Kalvin Narceau,Théo Richard et al.
