MO-A-217A-02: Prostate and Pelvic Lymph Node Anatomy for Contouring

Area of Science:

• Radiotherapy
• Medical Imaging
• Anatomy

Background:

• Three-dimensional image-guided radiotherapy necessitates a thorough understanding of human anatomy for accurate target volume contouring.
• The male pelvis presents unique anatomical challenges for radiotherapy treatment planning.

Purpose of the Study:

• To review the axial anatomy of the male pelvis using Visible Human Project images.
• To examine the formulation and clinical application of contouring guidelines for male pelvic radiotherapy.

Main Methods:

• Utilizing anatomical images from the Visible Human Project.
• Reviewing existing literature on pelvic contouring guidelines.
• Demonstrating the application of these guidelines on CT image sets.

Main Results:

• Identification of key anatomical landmarks in the male pelvis crucial for contouring.
• Understanding the basis and structure of established contouring guidelines.
• Practical demonstration of applying contouring guidelines in a clinical context.

Conclusions:

• Familiarity with male pelvic axial anatomy is essential for accurate radiotherapy contouring.
• Established contouring guidelines provide a framework for consistent and effective treatment planning.
• Clinical application of these guidelines enhances precision in 3D image-guided radiotherapy.
