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

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

Automated Quantitative Analysis of a Mouse Model of Chronic Pulmonary Inflammation using Micro X-ray Computed Tomography [PDF]

, 2011
Micro-CT has emerged as an excellent tool for in-vivo imaging of the lungs of small laboratory animals. Several studies have shown that it can be used to assess the evolution of pulmonary lung diseases in longitudinal studies.

In silico modeling of oxygen-enhanced MRI of specific ventilation. [PDF]

, 2018
Specific ventilation imaging (SVI) proposes that using oxygen-enhanced 1H MRI to capture signal change as subjects alternatively breathe room air and 100% O2 provides an estimate of specific ventilation distribution in the lung.

Integrating fetal pulmonary artery doppler with 2D lung volumetry to predict neonatal respiratory distress

The Egyptian Journal of Radiology and Nuclear Medicine
Objectives This study aims to evaluate fetal lung development through volumetric measurements and Doppler assessments of the main pulmonary artery, thereby correlating these findings with neonatal respiratory distress and Apgar score.

Comparison of Image Registration Based Measures of Regional Lung Ventilation from Dynamic Spiral CT with Xe-CT

, 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

Assessment of pulmonary edema: principles and practice [PDF]

, 2018
Pulmonary edema increasingly is recognized as a perioperative complication affecting outcome. Several risk factors have been identified, including those of cardiogenic origin, such as heart failure or excessive fluid administration, and those related to ...

Measuring the effect of airway pressure on pulmonary arterial diameter in the intact rat lung [PDF]

, 2003
To study the relationship between transpulomnary pressure (Ptp), intravascular pressure (Pv), and the pulmonary arterial tree structure, morphometric measurements of pulmonary arterial trees were made in intact lungs from Sprague-Dawley rats.
