Diagnostics and treatment of neurological disorders is based on continuous evaluation of the amount of clinical data and their various characteristics. Rising of the quantity of information with different clinical meaning which needs to be assessed is connected with the development of new diagnostic and medical methods. To understand recovery processes in the brain, some researchers are using new graphic diagnostic methods include for instance perfusion computed tomography (CTP), CT angiography or diffusion weighted magnetic resonance MR DWI to better understand the human brain regions i.a. involved in speaking and understanding language. The goal is achieved in various projects funded by the Czech Research Foundation (project number 106/09/0740) and Czech Ministry of Education (the project number 2C06009).
