This series of illustrations were done by a former BMC graduate, Ms. Myra Rudakewich. Unfortunately I couldn't locate the text that accompany these illustrations...
Source: Medical Illustrator Portfolio
Purpose: To provide a general overview and highlight key steps in the SNB procedure
Target audience: Undergraduate students
Strengths:
- Provides a complete overview of the SNB procedure
- Sequential images gives a linear flow of information, guiding the viewer step by step
- Insets are useful to fill in details (e.g. Histological section of injection, basic concepts of lymph circulation, radioactive readings)
- Layout is clear and concise, allowing the story to flow without obstruction or confusion
Weaknesses:
- Limited text; cannot communicate further concepts simply with illustrations
- The injection site should be at the tumor site; the illustration does not seem to clarify this
- Does not explain the injection of two materials: The radioactive tin colloid and the methyl blue dye, as well as their respective roles in the SNB procedure
- The series seem to stop once a single sentinel lymph node is found and dissected, while in reality, the axilla is explored to detect neighboring lymph nodes
- The procedure that determines the presence of metastatic cells in the sentinel lymph node seem to be over-simplified
