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 ...

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

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.

Flow-controlled ventilation (FCV) improves regional ventilation in obese patients – a randomized controlled crossover trial

BMC Anesthesiology, 2020
Background In obese patients, high closing capacity and low functional residual capacity increase the risk for expiratory alveolar collapse. Constant expiratory flow, as provided by the new flow-controlled ventilation (FCV) mode, was shown to improve ...

Pulmonary Densitovolumetry Using Computed Tomography in Patients with Nontuberculous Mycobacteria: Correlation with Pulmonary Function Tests

Pulmonary Medicine, 2019
Background. Since nontuberculous mycobacterial pulmonary disease (NTM-PD) is a condition with increasing morbidity, a more detailed knowledge of radiological aspects and pulmonary function plays a relevant role in the diagnosis and appropriate ...
