Water excitation MPRAGE: An alternative sequence for postcontrast imaging of the abdomen in noncooperative patients at 1.5 Tesla and 3.0 Tesla MRI
(JOHN WILEY & SONS INC, 2008)
Purpose: To evaluate the diagnostic image quality of post-gadolinium water excitation-magnetization-prepared rapid gradient-echo (WE-MPRAGE) sequence in abdominal examinations of noncooperative patients at 1.5 Tesla (T) ...
Self-supervised learning-based diffeomorphic non-rigid motion estimation for fast motion-compensated coronary MR angiography
(ELSEVIER SCIENCE INC, 2022)
Purpose: To accelerate non-rigid motion corrected coronary MR angiography (CMRA) reconstruction by developing a deep learning based non-rigid motion estimation network and combining this with an efficient implementation ...
Imaging artifacts in MRI simulators
(2011)
Artifactual images are created in the process of imaging. They are images that distort reality, i.e. they do not correspond to the image but they arise from them and are false. This paper describes image artifacts in MR ...
Mr-dti rician denoising
(Universidad Nacional de Colombia Sede Medellín, 2013)
In this work we tackle the problem of Magnetic Resonance Images (MRI) Rician denoising to enhance Diffusion Tensor Image (DTI) reconstruction. In a variational framework based on the Total Variation operator, the model of ...
3D MR coronary artery segmentation
(LIPPINCOTT WILLIAMS & WILKINS, 1998)
Coronary arteries are segmented from the blood pool using mathematical morphology operations from a 3D magnetic resonance spiral acquisition on a continuously breathing healthy volunteer. The segmented volume is maximal ...

MULTILINE DOPPLER IMAGING OF MR SER IN HIGH STATE
(IOP PUBLISHING LTD, 2009)
Doppler images in Balmer, He I, He II and C II lines, and simultaneous I-band photometry of the polar MR Ser are presented and analyzed. The Balmer and Helium Doppler tomograms, of this bright polar at high mass transfer ...
