Savi-Scout Radar Localization: Transitioning From the Traditional Wire Localization to Wireless Technology for...

Area of Science:

• Oncology
• Radiology
• Surgical Guidance

Background:

• Breast-conserving surgery necessitates precise lesion localization.
• Traditional wire localization is an established but invasive presurgical method.
• Advancements have introduced wireless technologies as alternatives to wire localization.

Purpose of the Study:

• To review the literature on the SaviScout radar (SSR) system for presurgical tumor localization.
• To share institutional experience with the SSR system.
• To compare SSR with traditional wire localization techniques.

Main Methods:

• Literature review of wireless tumor localization technologies.
• Description of the SSR system: a non-radioactive reflector implanted under imaging guidance.
• Confirmation of reflector placement via a handheld probe system.

Main Results:

• Surgical outcomes using SSR are comparable to those achieved with wire localization.
• The SSR system offers operational advantages, decoupling reflector placement from surgical scheduling.
• SSR technology presents an increased cost compared to wire localization.

Conclusions:

• The SaviScout radar system is a viable, non-radioactive alternative for breast tumor localization.
• SSR provides significant operational benefits for scheduling and workflow.
• Cost-effectiveness remains a consideration when comparing SSR to wire localization.
