PET-CT guided robotic biopsies - An institutional experience

USG and CT-guided biopsies have been the primary methods for obtaining tissue samples. CTguided biopsies are generally considered reliable, with reported accuracy rates ranging from 80% to over 98%. Patient-related factors, such as body habitus, breathing patterns, and anatomical considerations, also impact procedural success and accuracy. Failed biopsies can result from various factors, preventing the acquisition of precise tissue samples. This study was conducted to evaluate the benefits and limitations of PET-CT guided robotic biopsies at a tertiary care center. PET-CT guided biopsies were performed on Perfint Robio system by team of two Nuclear Medicine physicians and two technologists. The note was made of the procedure time, number of needle passes, check PET-CT scans. The suggested needle length by the machine is 30 mm longer than the target depth, with minimum being 40mm and 155mm with an average depth of 83.8mm. Robotic guided PET-CT biopsies are user friendly and aid medical professionals in adapting to its application, thereby reducing the learning curve. It offers navigation of needle through complex trajectories with reliable accuracy decreasing the procedure time and number of needle pass and check CT. By minimizing operator fatigue it enables consistent and reproducible results, Moreover it streamlines the biopsy process, potentially reducing patient discomfort and recovery time. The decision to use robotic technology should be made based on a thorough evaluation of the specific clinical scenario and available resources
