Official title
Phase II Trial Comparing 4-Dimensional Computed Tomography Derived Ventilation Versus SPECT/CT Tc-99m Aerosol Ventilation in Patients With Thoracic Malignancies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Objectives: Primary Objective: 1\. To determine the correlation between 4-dimensional computed tomography (4D CT) derived ventilation and single photon emission tomography (SPECT) aerosol Tc-99m determined ventilation. Secondary Objective: 1. To evaluate the reproducibility of the 4D CT derived ventilation and to obtain an estimate of the variance in a single setting. 2. To assess the correlation between hypoperfused and hypoventilated pulmonary regions in patients with thoracic malignancies. 3. To investigate the effect of continuous positive airway pressure (CPAP) on ventilation and tumor motion.
