•      Primary Applications for Lymphoscintigraphy:

•  melanoma

• breast carcinoma  

•     Lymphatic drainage map

•     Does NOT detect tumor invasion

•     Sentinel node detection

•      Probe detector useful  

• Lymphoscintigraphy of Malignant Melanoma
  
  
  

• Lymphoscintigraphy of Breast Carcinoma

• Lymphoscintigraphy of Internal Mammary Node Chain

•  Deep vs Intradermal Injection

  • Intradermal may be more painful

  • More failures with deep

  • Deep may show internal nodes better

• Sentinel Lymph Node Detection

  •      Requires use of intraoperative probe

  •      Can reduce OR time

  •      May help to stage cancer patients

  •      May reduce unnecessary surgery

  •      May reduce morbidity
