To know the current status of the technique of radioguided localisation of non-palpable breast lesions with or without indication for selective sentinel node biopsy -ROLL, SNOLL and 125I seeds- by conducting a national survey developed by the Working Group on Radioguided Surgery (GTCRG) of the Spanish Society of Nuclear Medicine and Molecular Imaging (SEMNIM). In October 2020, the form was sent in digital format to the different nuclear medicine services in Spain. A response time of 2 months with an overtime of 15 days was given. The number of ROLL/SNOLL procedures in each centre and the methodology used were obtained, including important technical details. In addition, a specific section on 125I seeds was included. The results were automatically downloaded into an Excel 2007 spreadsheet for subsequent analysis with the same program. The survey was answered by 55 centres; 21 use wire-guided localisation while the remaining 34 use different radioguided surgery techniques (RGS) for the localisation of non-palpable breast lesions, with the results itemized into thirteen sections. The commonly used tracer dose is 111 MBq for the ROLL technique and 222 MBq for the SNOLL technique, with a volume of 0.2 ml. The most common protocol is the two-day protocol. 26% of centres performing CRG use 125I seeds for both breast lesion and suspicious/pathological node detection, with the time between implantation and removal being about 3 days, with subsequent radiological control in most cases. The survey shows the relevance of radioguided surgery in the management of breast cancer patients at different stages of the disease, with disparity in the implementation of new techniques and tools, which responds to the multiple healthcare realities of Nuclear Medicine services. Conocer el estado actual de la técnica de localización radioguiada de lesiones no palpables de mama con o sin indicación de biopsia selectiva de ganglio centinela —ROLL, SNOLL y semillas de 125I— mediante la realización de una encuesta nacional elaborada por el Grupo de Trabajo de Cirugía Radioguiada (GTCRG) de la Sociedad Española de Medicina Nuclear e Imagen Molecular (SEMNIM). En octubre del 2020 se envió la encuesta, en formato digital, a los distintos servicios de Medicina Nuclear de nuestra geografía. Se dio un tiempo de respuesta de 2 meses con prórroga de 15 días. Se ha obtenido el número de procedimientos ROLL/SNOLL de cada centro y la metodología utilizada, recogiendo importantes detalles técnicos.
