Model selection and estimation of multi-compartment models in diffusion MRI with a Rician noise model.
Zhu X, Gur Y, Wang W, Fletcher PT. Zhu X, et al. Inf Process Med Imaging. 2013;23:644-55. doi: 10.1007/978-3-642-38868-2_54. Inf Process Med Imaging. 2013. PMID: 24684006 Free PMC article.
To model the noise distribution intrinsic to dMRI measurements, we introduce a Rician likelihood term and estimate the model parameters by means of an Expectation Maximization (EM) algorithm. This paper also addresses the problem of selecting the number of fiber compartmen …

LOW-ORDER 4D DYNAMICAL MODELING OF HEART MOTION UNDER RESPIRATION.
Queralt Madrigal M, Tadmor G, Crosas Cano G, Brooks DH. Queralt Madrigal M, et al. Proc IEEE Int Symp Biomed Imaging. 2011 Mar 30;2011:1326-1329. doi: 10.1109/ISBI.2011.5872645. Proc IEEE Int Symp Biomed Imaging. 2011. PMID: 21927642 Free PMC article.
This work is motivated by the limitations of current techniques to visualize the heart as it moves under contraction and respiration during interventional procedures such as ablation of atrial fibrillation. Our long-term goal is to integrate high resolution models routinel …

MRI of the left atrium: predicting clinical outcomes in patients with atrial fibrillation.
Daccarett M, McGann CJ, Akoum NW, MacLeod RS, Marrouche NF. Daccarett M, et al. Expert Rev Cardiovasc Ther. 2011 Jan;9(1):105-11. doi: 10.1586/erc.10.177. Expert Rev Cardiovasc Ther. 2011. PMID: 21166532 Free PMC article. Review.
In the last decade, catheter ablation has provided an improvement in morbidity and quality of life, significantly reducing long-term healthcare costs and avoiding recurrences compared with drug therapy. ...

Echocardiographic left atrial reverse remodeling after catheter ablation of atrial fibrillation is predicted by preablation delayed enhancement of left atrium by magnetic resonance imaging.
Kuppahally SS, Akoum N, Badger TJ, Burgon NS, Haslam T, Kholmovski E, Macleod R, McGann C, Marrouche NF. Kuppahally SS, et al. Am Heart J. 2010 Nov;160(5):877-84. doi: 10.1016/j.ahj.2010.07.003. Am Heart J. 2010. PMID: 21095275 Free PMC article.
Two-dimensional echocardiography, LA strain, and strain rate during left ventricular systole by velocity vector imaging were performed pre and at 6 3 months postablation. The long-term outcome was monitored for 12 months. RESULTS: Patients in group 1 were younger (57 15 vs …
