Review Article

Aim: The purpose of this study was to conduct a systematic review of the published literature to assess the role (indications, advantages, and limitations) of SPECT/CT for the detection of sentinel lymph node (SLN) in breast cancer.

Methods: The authors searched PubMed for published literature in English addressing this topic.

Results: Eleven studies, published since 2006, focused on the role and value of SPECT/CT for SLN detection (SLND). They showed that SPECT/CT improved sentinel node detection and anatomical localization. One study suggested that SPECT/CT may provide a more accurate staging. Limitations for SLND with SPECT/CT include extra time and inconvenience for the patient and additional radiation dose.

Conclusions: SPECT/CT is a valuable tool for SLND, especially in difficult cases, when planar lymphoscintigraphy shows no SLN or unexpected lymphatic drainage.
