Hyperpolarized Nuclei for NMR Imaging and Spectroscopy – Methodology and model studies of lung and vascular function
… (SNR) as high as ~500. To investigate regional pulmonary ventilation, a technique was developed in an initial study, that was based on inhalation of 3He gas. A quantitative measurement of gas replacement was calculated from the signal buildup after repeated inspirations of 3He. The relative …

In silico modelling to advance arterial spin labelling magnetic resonance imaging
… imaging methodology used for the measurement of pulmonary perfusion. Unlike other pulmonary perfusion imaging techniques such as Positron emission tomography (PET), Single-photon emission computed tomography and Computed tomography (CT), ASL MRI does not involve the use of ionising radiations; …

Physics-Based Computational Modeling of Mechanics and Perfusion in COVID-19 Infected Lungs
… Studying COVID-19 infected lung mechanics and perfusion provides a unique opportunity to advance our foundational knowledge of lung dynamics in a disease state. Lung mechanics emerge from the complex structure of the microscale lung; hence, understanding lung micro- and meso-scale mechanical …

Kontrollierte Perfusion der Lunge als neue Strategie zur Lungenprotektion während kardiopulmonalem Bypass
… Lunge einhergeht und ob 2.) eine kontrollierte Perfusion der Lunge mit autologem Blut während CPB diese Veränderungen vermindern kann. <br>Methoden: <br>In einer ersten Untersuchungsphase wurden 14 Tiere für 120 min an den CPB angeschlossen. Dabei wurde bei 5 Tieren die Lunge während des CPB …

Evaluation of Deformable Image Registration For Improved 4D Ct-Derived Ventilation For Image Guided Radiotherapy
<p>Recent treatment planning studies have demonstrated the use of physiologic images in radiation therapy treatment planning to identify regions for functional avoidance. This image-guided radiotherapy (IGRT) strategy may reduce the injury and/or functional loss following thoracic radiotherapy. 4D …
