Dual-energy micro-CT functional imaging of primary lung cancer in mice using gold and iodine nanoparticle contrast agents: a validation study. [PDF]
PLoS ONE, 2014 PURPOSE:To provide additional functional information for tumor characterization, we investigated the use of dual-energy computed tomography for imaging murine lung tumors. Tumor blood volume and vascular permeability were quantified using gold and iodine

A damaged-informed lung model for ventilator waveforms [PDF]
arXiv, 2020 The acute respiratory distress syndrome (ARDS) is characterized by the acute development of diffuse alveolar damage (DAD) resulting in increased vascular permeability and decreased alveolar gas exchange. Mechanical ventilation is a potentially lifesaving intervention to improve oxygen exchange but has the potential to cause ventilator-induced lung ...

Comparison of Image Registration Based Measures of Regional Lung Ventilation from Dynamic Spiral CT with Xe-CT [PDF]
, 2012 Purpose: Regional lung volume change as a function of lung inflation serves as an index of parenchymal and airway status as well as an index of regional ventilation and can be used to detect pathologic changes over time. In this article, we propose a new regional measure of lung mechanics --- the specific air volume change by corrected Jacobian ...

Pressure- and time-dependent alveolar recruitment/derecruitment in a spatially resolved patient-specific computational model for injured human lungs [PDF]
arXiv, 2023 We present a novel computational model for the dynamics of alveolar recruitment/derecruitment (RD), which reproduces the underlying characteristics typically observed in injured lungs. The basic idea is a pressure- and time-dependent variation of the stress-free reference volume in reduced dimensional viscoelastic elements representing the acinar ...

Growth pattern analysis of murine lung neoplasms by advanced semi-automated quantification of micro-CT images. [PDF]
PLoS ONE, 2013 Computed tomography (CT) is a non-invasive imaging modality used to monitor human lung cancers. Typically, tumor volumes are calculated using manual or semi-automated methods that require substantial user input, and an exponential growth model is used to

Does Global Lung Initiative Obviate the Need for Lung Volume Measurements? [PDF]
Respiratory Care, 2017 Establishing the diagnosis of restrictive lung disease is often difficult and requires extensive testing not only to diagnose but also to accurately classify the underlying disease. Current clinical practice often involves an initial screening with spirometry and a subsequent measurement of ...
