Electrical Impedance Tomography of Stroke and Brain Injury

The purpose of this study is to determine if Electrical Impedance Tomography (EIT) can produce reproducible and accurate images in people with stroke or head injury compared to existing standards such as MRI, CT. Electrical Impedance Tomography is a relatively new medical imaging method, which has the potential to provide novel images of brain function. It is fast, portable, safe and inexpensive, but currently has a relatively poor spatial resolution. It produces images of the internal electrical impedance of a subject with stroke or head injury using rings of ECG like electrodes on the skin. EIT recording will take place as early as possible, usually within 24 hours of admission. Following completion of the recording, the EIT images will subsequently be analysed and compared to other imaging data for accuracy.

Effectiveness of 3D Bone Matrix in Cranioplasty

The objective of this clinical trial is to evaluate the effectiveness of a 3D bone scaffold in relation to a scaffold formed by PCL + β-TCP (polycaprolactone and beta-tricalcium phosphate), compared to the use of PMMA (polymethyl methacrylate) acrylic cement for bone regeneration in patients undergoing cranioplasty in the city of Valdivia, Chile, between the years 2024-2025. The main beneficiaries will be patients, users of the public or private health system, who require bone regeneration. The intermediate beneficiaries are the health team: doctors specialized in surgery and orthopedics, dedicated in their professional work to bone reconstruction and regeneration.
