Ins and Outs of 3D Female Pelvic Anatomy: A Hands on Approach
Sunday March 26, 2017 - 8:00 AM - 11:15 AM
Course Director: Lennox Hoyte MD, MSEECS
Course Faculty: John O. L. DeLancey, MD
A thorough understanding of the three dimensional relationship of the female pelvic organs and tissues is critical to the mastery of female pelvic surgery. To date, much of our understanding of the anatomic relationships of the pelvic organs and tissues stems from cadaveric dissections. However, in death, key tissues lose their shape and the anatomic relationships become distorted. Furthermore, tissue exposure during live surgery is ethically limited to the anatomic region requiring the surgical intervention. This combination of factors act to limit our ability to fully appreciate the true 3D pelvic anatomy in living women.
High resolution magnetic resonance imaging (MRI) permit access to the tissue level anatomy of the female pelvic organs and tissues in a non-invasive manner. However, the 2 dimensional “stacked image” rendition of the anatomy can limit a surgeon’s ability to “see” the fill 3D relationships between the organs in living women.
With the development of readily available public domain software for segmenting and 3D rendering of the MRI derived images from living women, Surgeons now have the ability to view and manipulate the female pelvic organs in 3D on the computer screen.
This course will teach the participant how to use the public domain 3D slicer software, and also how to manipulate a previously made MR-derived 3D pelvic floor model on their computer screen in order to study the detailed relationships between the organs and tissues.
Course Learning Objectives:
At the conclusion, the participant should be able to:
1) Learn how to use the public domain 3D slicer to study the 3D anatomy of the female pelvis
2) Learn to add, delete, and manipulate pelvic organs in the 3D view
3) Learn the geometric relationships of the pelvic organs and tissues from a 3D perspective.
