  • Title: Fusion lymphoscintigraphy with a 24-hour Tc-99m MDP bone scan for sentinel lymph node detection and imaging.
    Author: Tatini VR, Dworkin HJ.
    Journal: Clin Nucl Med; 2001 Jan; 26(1):53. PubMed ID: 11139054.
    Abstract:
    A 62-year-old woman with right breast carcinoma who had a breast biopsy 3 weeks earlier was referred for a whole-body Tc-99m MDP bone scan to identify possible osseous metastases. Twenty-four hours later, she underwent lymphoscintigraphy using four peritumoral injections of 250 microCi filtered Tc-99m sulfur colloid of 0.22 microm each. The lymphoscintigraphic images showed good delineation of three right axillary lymph nodes in relation to the rib cage. Performing a bone scan just before lymphoscintigraphy for sentinel node detection may help the surgeon to identify sentinel lymph nodes. This is more anatomically precise than using a flood source to delineate body contour. A Tc-99m MDP bone scan followed by lymphoscintigraphy should be considered in patients with breast carcinoma who will have both bone imaging and lymphoscintigraphy.
