Scintigraphic localization of bone lesions during surgery

Area of Science:

• Nuclear Medicine
• Surgical Oncology
• Medical Imaging

Background:

• Accurate surgical resection of bone lesions with increased radiotracer uptake is crucial.
• Minimally invasive techniques are sought to improve surgical outcomes and reduce recurrence.

Purpose of the Study:

• To evaluate the efficacy of intraoperative nuclear medicine imaging techniques for bone lesion removal.
• To assess the utility of preoperative localization and intraoperative monitoring in ensuring complete resection.

Main Methods:

• Discusses three intraoperative nuclear medicine procedures: remote control by imaging, intraoperative control by imaging, and intraoperative control by scintillation probe.
• All techniques involve preoperative injection of a bone imaging tracer.
• Utilizes gamma cameras for preoperative localization and intraoperative monitoring, and scintillation probes for direct intraoperative guidance.

Main Results:

• Preoperative localization using gamma cameras marks the skin over the lesion for optimal surgical planning.
• Intraoperative imaging and scintillation probes allow real-time monitoring of the resection process.
• Experience with 18 procedures in 15 patients demonstrated successful application of these techniques.

Conclusions:

• Intraoperative nuclear medicine imaging techniques, including remote and direct intraoperative control, enhance the accuracy of bone lesion removal.
• These methods provide valuable guidance for surgeons, ensuring complete resection and potentially improving patient outcomes.
• The study supports the continued use and further investigation of these nuclear medicine-guided surgical procedures.
