림프부종 평가를 위한 림프신티그라피: 대한핵의학회/대한림프부종학회 시행/판독 지침 1부

Lymphoscintigraphy is a non-invasive imaging technique that visualizes the function and structure of the lymphatic system by administering a radiopharmaceutical subcutaneously, which emits 140 KeV gamma radiation. It plays a crucial role in diagnosing and assessing lymphedema, evaluating disease severity, monitoring therapeutic responses, and predicting prognosis. This procedure involves the use of a gamma camera to capture images of the radiopharmaceutical’s movement through the lymphatic vessels, with the option of utilizing SPECT/CT to enhance anatomical accuracy. Prior to the procedure, it is essential to gather comprehensive clinical information, including the patient’s history of edema, family history, associated syndromes, malignancies, and prior treatments. The Korean Society of Nuclear Medicine and the Korean Society of Lymphedema prepared for the procedure and interpretation guideline of lymphoscintigraphy for lymphedema by consensus. This document included the indications, procedural steps, and technical considerations involved in lymphoscintigraphy for lymphedema among that guideline. Other parts of the guideline will be dealt with by the subsequent paper in the next issue of the journal.
