Human upper-airway respiratory airflow: In vivo comparison of computational fluid dynamics simulations and hyperpolarized 129Xe phase contrast MRI velocimetry.
Autor: Qiwei Xiao, Neil J Stewart, Matthew M Willmering, Chamindu C Gunatilaka, Robert P Thomen, Andreas Schuh, Guruprasad Krishnamoorthy, Hui Wang, Raouf S Amin, Charles L Dumoulin, Jason C Woods, Alister J Bates
Publikováno v: PLoS ONE, Vol 16, Iss 8, p e0256460 (2021)
Computational fluid dynamics (CFD) simulations of respiratory airflow have the potential to change the clinical assessment of regional airway function in health and disease, in pulmonary medicine and otolaryngology. For example, in diseases where mul

Lung microstructure in adolescent idiopathic scoliosis before and after posterior spinal fusion.
Autor: Robert P Thomen, Jason C Woods, Peter F Sturm, Viral Jain, Laura L Walkup, Nara S Higano, James D Quirk, Brian M Varisco
Publikováno v: PLoS ONE, Vol 15, Iss 10, p e0240265 (2020)
Adolescent idiopathic scoliosis (AIS) is associated with decreased respiratory quality of life and impaired diaphragm function. Recent hyperpolarized helium (HHe) MRI studies show alveolarization continues throughout adolescence, and mechanical force

Improved visualization of free-running cardiac magnetic resonance by respiratory phase using principal component analysis
Autor: Ummul Afia Shammi, Zhijian Luan, Jia Xu, Aws Hamid, Lucia Flors, Joanne Cassani, Talissa A. Altes, Robert P. Thomen, Steven R. Van Doren
Publikováno v: Research in Diagnostic and Interventional Imaging, Vol 8, Iss , Pp 100035- (2023)
Rationale and objectives: To support cardiac MR acquisitions during breathing without ECG, we developed software to mitigate the effects of respiratory displacement of the heart. The algorithm resolves respiratory motions and cardiac cycles from DICO

Comparison of Hyperpolarized 3He and 129Xe MR Imaging in Cystic Fibrosis Patients
Autor: Kun Qing, F. William Hersman, Jamie Mata, Iulian C. Ruset, Talissa A. Altes, John P. Mugler, Craig H. Meyer, Robert P. Thomen, Ummul Afia Shammi, Michelle Felicia D'Alessandro
Publikováno v: Academic Radiology. 29:S82-S90
PURPOSE In this study, we compared hyperpolarized 3He and 129Xe images from patients with cystic fibrosis using two commonly applied magnetic resonance sequences, standard gradient echo (GRE) and balanced steady-state free precession (TrueFISP) to qu

Simplification of free-running cardiac magnetic resonance by respiratory phase using principal component analysis
Autor: Ummul Afia Shammi, Zhijian Luan, Jia Xu, Aws Hamid, Lucia Flors, Joanne Cassani, Talissa A. Altes, Robert P. Thomen, Steven R. Van Doren
Cardiac magnetic resonance imaging (CMR) provides many cardiac functional insights. The reliance of standard cine CMR upon breath holds is not feasible for some patients. Its process of combining multiple heartbeats is unsuited to arrhythmias. Real-t

Alveolar Airspace Size in Healthy and Diseased Infant Lungs Measured via Hyperpolarized 3He Gas Diffusion Magnetic Resonance Imaging
Autor: Heidie Huyck, Gloria S. Pryhuber, Nara S. Higano, James D. Quirk, Robert P. Thomen, Jason C. Woods, Sean B. Fain, Andrew D. Hahn
Publikováno v: Neonatology. 117:704-712
Background: Alveolar development and lung parenchymal simplification are not well characterized in vivo in neonatal patients with respiratory morbidities, such as bronchopulmonary dysplasia (BPD). Hyperpolarized (HP) gas diffusion magnetic resonance

Improving hyperpolarized 129 Xe ADC mapping in pediatric and adult lungs with uncertainty propagation
Autor: Laura L. Walkup, Abdullah S. Bdaiwi, Matthew M. Willmering, Zackary I. Cleveland, Peter J. Niedbalski, Monir Hossain, Robert P. Thomen, Hui Wang, Kai Ruppert, Jason C. Woods
