CT in Diagnosing Patients With Lung Cancer

July 6, 2016 updated by: Virginia Commonwealth University

Comparison of Conventional Free Breathing CT, 4D CT, and Integrated Active Breath Hold CT Image Acquisition for Lung Cancer

This clinical trial studies computed tomography (CT) in diagnosing patients with lung cancer. Diagnostic procedures, such as CT, may help find and diagnose lung cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. Conduct a prospective clinical imaging study to quantify the amount of inter- and intra-physician contouring variability on four dimensional (4D) CT, active breathing control (ABC) CT, free breathing CT, and free breathing and ABC cone beam (CB)CT.

II. Quantify the magnitude and distribution of target and organ at risk volume variations between the different imaging modalities.

III. Determine dosimetric changes related to contouring variations for tumor and normal tissue.

OUTLINE:

Patients undergo conventional free breathing CT, 4D CT, ABC CT, ABC CBCT, and free breathing CBCT before undergoing radiation therapy.
