Dependence of ventilation image derived from 4D CT on deformable image registration and ventilation algorithms
Ventilation imaging using 4D CT is a convenient and low-cost functional imaging methodology which might be of value in radiotherapy treatment planning to spare functional lung volumes. Deformable image registration (DIR) is needed to calculate ventilation imaging from 4D CT. This study investigates the dependence of calculated ventilation on DIR methods and ventilation algorithms. DIR of the no...
متن کاملReversal Trend of Hounsfield Unit Values of Substances with High and Low Effective Atomic Numbers
Introduction: In dual-energy computed tomography (DECT), the Hounsfield values of a substance measured at two different energies are the basic data for finding the chemical properties of a substance. The trends of Hounsfield unit (HU) alterations following the changes in energy are different between the materials with high and low Zeff. The present study aim...
متن کاملEvaluation of Four-dimensional (4D) Computed Tomography (CT) Pulmonary Ventilation Imaging by Comparison with Single Photon Emission Computed Tomography (SPECT) Scans for a Lung Cancer Patient
The goal of this study was to present a method for physiologic validation and show results for a comparison of the 4D-CT ventilation and SPECT ventilation or perfusion. A 4D-CT and a SPECT ventilation/perfusion (V/Q) (VSPECT and QSPECT) scans were acquired for a lung cancer patient. Two 4D-CT ventilation images were created using two metrics: Hounsfield unit (HU)-change (V4D-CT) and Jacobian de...
متن کاملEstimating lung volume during high frequency ventilation
The primary goals of lung ventilation are to bring oxygen into the alveoli from where it can enter the blood, and to eliminate carbon dioxide dissolved in the blood. Since CO2 is much more soluble in blood than oxygen, O2 transport is diffusion-limited and a large alveolar surface area is the primary factor controlling its delivery. CO2 transport is flow-limited, so that efficient gas transport...
متن کاملNormative Vertebral Hounsfield Unit Values and Correlation with Bone Mineral Density
Background: We hypothesized that vertebral bone mineral density as measured in Hounsfield units (HU) by computed tomography (CT) can correlate with values obtained by dual x-ray absorptiometry (DXA). Our study aimed to report such a correlation along with the normative HU values within a large, heterogeneous population. Methods: We identified 2,020 trauma patients with a CT scan encompassing an...
