Description
Pre-operative planar scintigraphy and intra-operative probe detection have been performed in a variety of solid tumors in the last decade.
Actually the new nuclear medicine tool is to better localize sentinel node and discover deeply located ones in mediastinum , abdomen and pelvis .
Moreover, to improve anatomical information, hybrid imaging devices such as SPECT-CT and PET-CT , that combine nuclear functional information with CT morphological data , have been introduced.
Portable mini-gamma-camera can help the surgeon especially in the colon-surgery, in which investigators have a high false negative rate because of the lack of imaging.
Portable devices are particularly useful in laparoscopic surgery because combine real time findings and pre-operative imaging and are able to depict the signals of two radionuclide simultaneously.
New generation probe are able to better identify radioactive signals both from tumor both from lymphonodes and to guide the surgeon to a selective lymphadenectomy.
This new investigation area can help the crucial point in decision making in gastrointestinal tumor management, about a less or more extensive surgery , to recognize sentinel node and to excide it for histopathology such as in early gastric cancer, where a simply mucosectomia can be performed, if negative pathological node has been found.
