A Comprehensive Assessment of Lung Structure and Function via Dynamic, Volumetric X-ray CT
Overview
Measures Included in a Comprehensive Assessment of the Lung
EBCT/Multislice Helical
Lung Volume Controller to assure standardization of lung inflation during scan
Stable Xenon Gas as a CT Contrast Agent for the Assessment of Regional Ventilation
Multi-breath Washout Subtraction Images
Repeatability of Tracer Clearance Data
Flow Rate Dependence : Increased Role of Conductance with Increased Inspiratory Flow Rate
Single Breath Protocol With Prolonged Apnea For Use with Helical CT: Instability of Dependent Lung Density
Pulmonary Blood Flow
Distribution of PBF (ml/gm/min)
System Description: Bolus Injection, Residue Detection
Filtered FFT Deconvolution w/ Inverted Hanning Window
Deconvolution-Based Microvascular Microvascular Mean Transit Times
Adaptive Multiple Feature Method (AMFM)
Baysian Classifier
Anterior-Posterior differences
Global - Normal vs. IPF
Global - IPF vs. Sarcoidosis
Regional analysis
Observer validation scheme
Three readings by example reader for an emphysema slice
Validation results third session
