Accurate localisation of non-palpable breast lesions is essential for effective surgical excision, yet conventional methods present significant limitations. Wire-guided localisation often results in scheduling constraints and the risk of wire migration, while radioactive seed localisation raises concerns regarding radiation exposure for both patients and clinical staff. The Sirius Pintuition system offers a novel, wire-free, and non-radioactive magnetic seed-based localisation technology designed to address these challenges. This technique involves the preoperative percutaneous implantation of a magnetic Pintuition seed into the lesion under imaging guidance. Intraoperatively, the seed is detected using a handheld probe connected to a base unit that provides real-time visual and auditory feedback, allowing precise localisation from distances up to 50 mm. GPSDetect allows for the proximity of the probe to the lesion to be understood both radially and in terms of depth in millimetres, whilst TargetLOC reveals when the probe is directly aimed at the Pintuition marker. This enables surgeons to identify target lesions accurately without reliance on wires or radioactive materials. Clinical experience demonstrates that the system is safe, accurate, and enhances surgical workflow efficiency (Stengs et al., Breast Glob J 1:49, 2023). The successful adoption of Pintuition depends on a coordinated multidisciplinary approach involving radiologists and surgeons, improving scheduling flexibility and overall procedural logistics. This technology represents a promising advancement in breast conserving surgery and could potentially streamline the localisation of other soft tissue lesions. Early research studies are described, whilst further prospective studies are needed to validate its long-term efficacy and cost-effectiveness in routine clinical practice.
