lymphoscintigraphy

lymphoscintigraphy

 [lim″fo-sin-tig´rah-fe]
scintigraphic detection of metastatic tumors in radiolabeled lymph nodes, particularly that using radiolabeled colloid (radiocolloid lymphoscintigraphy). The colloid is taken up by macrophages in the lymph nodes, with depressed uptake in tumor-containing nodes.

(lim'fō-sin-tig'ră-fē),
Scintillation scanning of lymphatics or lymph nodes following intralymphatic or subcutaneous injection of a radionuclide.

lymphoscintigraphy

/lym·pho·scin·tig·ra·phy/ (-sin-tig´rah-fe) scintigraphic detection of metastatic tumor in radioactively labeled lymph nodes, particularly that using radioactively labeled technetium colloid (radiocolloid l.).

lymphoscintigraphy

[-sintig′rəfē]
a diagnostic technique using scintillation scanning of technetium-99m antimony trisulfide colloid in a noninvasive test for primary and secondary lymphedema. The radiopharmaceutical is injected subcutaneously in the interdigital space of the hands and feet.

lymphoscintigraphy

use of a radionuclear agent to demonstrate a lymphatic drainage system, using scintigraphy.

Morton introduced cutaneous lymphoscintigraphy to identify, or map, the regional lymphatic basin receiving drainage from a primary cutaneous melanoma.
At centres with the appropriate expertise, dynamic sentinel lymph node biopsy (which involves the injection of technetium-99m around the primary tumour), preoperative lymphoscintigraphy, and sentinel lymph node (SLN) identification using blue dye and a gamma ray detection probe to achieve physiologic rather than anatomic SLN identification may be considered.
Surgeons from North America, Europe, Asia, and Israel provide 25 chapters that cover etiology and epidemiology, including the role of HIV infections and human papillomavirus in head and neck tumors; biochemoprevention, immunology and immunotherapy, imaging, staging, pathology, radiation therapy, chemotherapy and targeted treatment, photodynamic therapy, evaluation and treatment planning, salvage surgery, lymphoscintigraphy and sentinel node biopsy, indications and modifications of neck dissection, pain and symptom management, physical and occupational therapy, nutrition support, voice rehabilitation, and quality of life; cutaneous malignancies; and tumors in children.
Lymphangiography (the gold standard exam) or lymphoscintigraphy can be performed to confirm communication with the thoracic duct.
Extension of the lesion to the lymph nodes has been assessed with various approaches including lymphoscintigraphy, whole body PET/CT scan, (38) MRI, ultrasonography with FNA biopsy of suspicious lymph nodes, (39) or sentinel node biopsy.
For patients with disease that is apparently clinically localized to the primary tumor site, identifying the sentinel lymph nodes by lymphoscintigraphy for subsequent close monitoring by clinical examination and ultrasonography appears to offer an alternative, noninvasive strategy to sentinel lymph node biopsy that may allow early detection of growing metastases.
