lymphoscintigraphy
Pronunciation: LIM-foh-sin-TIG-rah-fee
Nuclear medicine imaging study to map lymphatic drainage patterns.
Full Definition
Lymphoscintigraphy involves injection of radioactive colloid around a tumor site followed by gamma camera imaging to visualize lymphatic drainage pathways and identify sentinel lymph nodes. This technique is essential for sentinel lymph node biopsy procedures and provides anatomic mapping that varies among patients. The study helps guide surgical planning and reduces the risk of missing relevant nodal basins. Proper timing and technique are critical for optimal sentinel node identification.
Usage
Usage note: Essential component of sentinel lymph node biopsy protocols.
