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),

In a separate study that combined the intraoperative blue-dye technique with preoperative lymphoscintigraphy, 139 sentinel nodes in 95 of 107 groins (89%) in 59 patients with T1 or T2 squamous cell carcinoma of the vulva were identified, reported Dr.
The purpose of this study was to evaluate the necessity and utility of PET/CT imaging that was performed within the first year in patients with a diagnosis of CM, whose SLN(s) have previously been biopsied by either blue dye injection or lymphoscintigraphy and had negative results for metastasis.
We would have considered lymphoscintigraphy, but it was not possible in our setup.
Location of the reoperated sentinel nodes in lymphoscintigraphy presented 70% in ipsilateral axilla only and 30% in non-axillary region (mainly internal mammary node followed by contralateral axilla).
