Prostate Delineation: High Quality Volume CT

Official Title

Prostate Delineation During Radiation Treatment Planning for Prostate Cancer: Comparison of High Quality Volume Computerized Tomography With Conventional Tomography and Magnetic Resonance Imaging


This study will look at how feasible it is to use a certain type of Computed Tomography (CT) to scan prostate cancer, called a high quality volume CT scan. It is hoped that this technique will help doctors provide a higher-quality image of the prostate cancer, making it easier to plan the area that will be treated. Using this type of CT scan will also lessen the amount of time patients spend in the scanner. This study will not offer patients a different treatment for their prostate cancer. Patients will receive the most appropriate standard treatment whether or not they are in this study.

Trial Description

Primary Outcome:

  • Using different scanning methods for patients undergoing radical external beam radiation therapy for prostate cancer to determine inter-observer variability in prostate gland delineation on the images.
Secondary Outcome:
  • Determine the concordance between delineators in identifying the prostate apex on the 2 CT image sets. MRI will be considered the "gold-standard" for identifying the prostate apex.
