Fluorescence guided surgery (FGS), also called fluorescence image-guided surgery, or in the specific case of tumor resection, fluorescence guided resection, is a medical imaging technique used to detect fluorescently labelled structures during surgery. [1]
She is known for her work pioneering fluorescence guided surgery and co-holds several patents with Nobel Laureate Roger Y. Tsien, PhD [2] pertaining to their invention of peptides, [3] imaging systems and methods to support fluorescence-guided cancer tumor resection and fluorescent labeling of nerves on the surgical bed. [4]
Pegulicianine (Lumisight) is indicated for fluorescence imaging in adults with breast cancer as an adjunct for the intraoperative detection of cancerous tissue within the resection cavity following removal of the primary specimen during lumpectomy surgery. [7] Photoactivated localization microscopy.
This use of fluorescent materials to make a viewing scope is how fluoroscopy got its name. As the X-rays pass through the patient, they are attenuated by varying amounts as they pass through or reflect off the different tissues of the body, casting an X-ray shadow of the radiopaque tissues (such as bone tissue) on the fluorescent
For this reason, a nerve resection may be considered after a failed decompression. Examples of nerves that may be good candidates for resection are lateral femoral cutaneous nerve, [42] zygomaticotemporal branch of the trigeminal nerve, [43] the posterior femoral cutaneous nerve, [44] [45] and the middle/superior cluneal nerves.

Fluorescein angiography [1] (FA), fluorescent angiography (FAG), or fundus fluorescein angiography (FFA) is a technique for examining the circulation of the retina and choroid (parts of the fundus) using a fluorescent dye and a specialized camera.
A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection (less precise), is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.
Mohs surgery is the gold standard method for obtaining complete margin control during removal of a skin cancer (complete circumferential peripheral and deep margin assessment - CCPDMA) using frozen section histology. [1] CCPDMA or Mohs surgery allows for the removal of a skin cancer with very narrow surgical margin and a high cure rate.
