Abnormal diastolic and systolic septal motion following pericardiectomy demonstrated by cine DENSE MRI

Author: Spottiswoode, Bruce ; Russell, James B ; Moosa, Sulaiman ; Meintjes, Ernesta M ; Epstein, Frederick H ; Mayosi, Bongani M Date: 2008 Constrictive pericarditis can lead to paradoxical interventricular septal motion. Displacement encoding with stimulated echoes (DENSE) magnetic resonance imaging (MRI) provides a method for quantifying myocardial motion and strain. A case of ... Read more
Assessing strain in arrhythmogenic right ventricular cardiomyopathy using cine DENSE MRI

Author: Ongori, Joash ; Hendricks, Neil ; Spottiswoode, Bruce ; Meintjes, Ernesta ; Epstein, Frederick ; Mayosi, Bongani Date: 2009 The kinematics of the right ventricle (RV) are not well understood due to its thin wall and asymmetric geometry. Cine displacement encoding with stimulated echoes (cine DENSE), which measures intramyocardial displacement and strain, has been ... Read more c b
Comparison of SNR efficiencies and strain for cine DENSE using conventional EPI, flyback EPI and spiral k-space trajectories

Author: Zhong, Xiaodong ; Spottiswoode, Bruce ; Meyer, Craig ; Epstein, Frederick Date: 2011 The original implementation of 2D cine DENSE (displacement encoding with stimulated echoes) employed a conventional EPI k-space trajectory for rapid data sampling. Follow-up studies used flyback EPI to reduce image artifacts. More recently a ... Read more c b
Comprehensive Cardiovascular magnetic resonance of myocardial mechanics in mice using three-dimensional cine DENSE

Author: Zhong, Xiaodong ; Gibberman, Lauren ; Spottiswoode, Bruce ; Gilliam, Andrew ; Meyer, Craig ; French, Brent ; Epstein, Frederick Date: 2011 BACKGROUND: Quantitative noninvasive imaging of myocardial mechanics in mice enables studies of the roles of individual genes in cardiac function. We sought to develop comprehensive three-dimensional methods for imaging myocardial mechanics ... Read more c b
Impact of childhood trauma on functionality and quality of life in HIV-infected women

Author: Troeman, Zyrhea ; Spies, Georgina ; Cherner, Mariana ; Archibald, Sarah ; Fennema-Notestine, Christine ; Theilmann, Rebecca ; Spottiswoode, Bruce ; Stein, Dan ; Seedat, Soraya Date: 2011 BACKGROUND:While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL) in HIV. METHODS: The present study focused on HIV in ... Read more c b
Mapping right ventricular myocardial mechanics using 3D cine DENSE cardiovascular magnetic resonance

Author: Auger, Daniel ; Zhong, Xiaodong ; Epstein, Frederick ; Spottiswoode, Bruce Date: 2012 BACKGROUND: The mechanics of the right ventricle (RV) are not well understood as studies of the RV have been limited. This is, in part, due to the RV's thin wall, asymmetric geometry and irregular motion. However, the RV plays an important ... Read more c b
Virtual reality exposure therapy as treatment for pain catastrophizing in fibromyalgia patients: proof-of-concept study (Study Protocol)

Author: Morris, Linzette ; Grimmer-Somers, Karen ; Spottiswoode, Bruce ; Louw, Quinette Date: 2011 BACKGROUND: Albeit exercise is currently advocated as one of the most effective management strategies for fibromyalgia syndrome (FMS); the implementation of exercise as a FMS treatment in reality is significantly hampered by patients' poor ...
