In recent years, predictive methods for assessing the preservation of the parathyroid glands have been actively implemented. The article describes the first experience of evaluating the blood supply of the parathyroid glands by quantitative determination of the indocyanine green (ICG) accumulation index in real time in 6 patients before and after a thyroidectomy with central neck lymph node dissection for papillary thyroid cancer. Intraoperative fluorescent angiography was performed by using domestic equipment with a fluorescent module, as well as by using a domestic medication of ICG.

Background: Two Bispectral contrast enhancement approaches for the fluorescence diagnosis with chlorine-e6 and a wide field-of-view imaging system with fluorescence excitation at 405 nm and time-resolved background suppression were analyzed and compared.

Methods: Two techniques for the contrast enhancement of a fluorescent video system (Red/Green (R/G) ratio and Red-Green (R-G)) with time-resolved background suppression for fluorescent diagnosis (FD) were tested in four patients with basal cell carcinoma (BCC).

Results: The results of both contrast enhancement methods were compared for the diagnostic efficiency for FD of BCC.

Article Synopsis
  • The study compared two wide field-of-view fluorescence imaging systems with different excitation wavelengths (405 nm and 635 nm) for diagnosing tumors.
  • Both systems were tested on tumor phantoms as well as in six patients with basal cell carcinoma and oral mucosa cancer, confirming the ability to define lesion boundaries and fluorescence intensity.
  • The 405 nm system outperformed the 635 nm system in distinguishing between tumor and healthy tissue for oral mucosal cancer, indicating greater effectiveness in eliminating background noise and providing consistent fluorescence quantification.
