A Polymer Thick Film on an organic substrate Grid Electrode for UHF MRI

Recent advancements in neuroimaging involve the development of a novel electrocorticography (ECoG) grid. This grid is crafted using a polymer-thick film on an organic substrate (PTFOS), a design that offers several significant improvements over conventional ECoG grids, including Reduced Imaging Artifacts: The PTFOS grid produces negligible artifacts on MR images image quality of brain tissue overlaid with PTFOS grids. Lower Temperature Increase During MRI: In a 30-minute MR imaging session, temperature increases with the PTFOS grid were extremely low (0.4°C). These findings suggest that electrocorticography obtained using PTFOS grids could potentially improve the safety and efficacy of neurosurgical procedures, offering clearer imaging results and reducing risk factors such as excessive heating during MRIs.
