This regular feature will enhance your knowledge of imaging technology
in oncologic diagnosis, treatment, and evaluation.
Case Description:
A 61-year-old woman originally presented with a palpable mass at the 7 o'clock position
of the right breast that proved to be a 1.0-cm infiltrating ductal carcinoma. A
lymphoscintigram and lymphatic mapping were performed prior to lumpectomy to aid in
selective axillary lymph node dissection (Figs 1A-B).
The following statement(s) is (are) true of lymphoscintigraphy:
1. There can be more than one sentinel lymph node.
2. The lymphoscintigram is usually not reproducible.
3. Lymphoscintigraphy is practically limited because of the high radiation burden
received by the patient.
4. Optimal lymphoscintigraphy imaging is achieved 12 hours postinjection.
