RESUMO
OBJECTIVES: Sentinel lymphoscintigraphy(SLSG) is focused on the visualization of an injection site and lymph nodes. Therefore, an anterior view is effective in identifying the location of a lymph node easily. For this reason, we devised a new imaging method of anterior view (Modified Anterior View; MAV), and the usefulness was assessed. METHODS: SLSG was obtained in 166 patients with breast cancer. In MAV imaging, patients were laid in an oblique position on a triangular styrene foam elevating the target axillary side. The detector was also leaned. Just after the MAV were imaged, the patient was shifted to the supine position and the SAV imaging was also performed using the same acquisition times. RESULTS: The detectability of MAV and SAV was 92.42% and 81.99%, respectively. However, the detectability of SAV showed the better value for the few cases which the lymph node detected by the inside of injection site. CONCLUSION: MAV may improve detectability of SLN. However, SAV is still required for a few cases in which lymph node is detected by the inside of injection site.
