Detailed Structure and Function of Lymph Nodes

5.4K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Abdominal Regions and Quadrants

18.7K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

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.
