MAP18

ABOUT

The Morphometric Analysis Program v2018 (short: MAP18) is intended to facilitate the detection and visualization of epileptogenic pathologies. As such it is successfully used in over 60 specialized epilepsy clinics worldwide. A major part of the program is dedicated to morphometric MRI analysis which compares the individual brain anatomy with a normal database and highlights deviations in terms of gyration, cortical thickness and grey-white matter differentiation. This shall improve the recognition and demarcation of focal cortical dysplasias (FCD) and other cortical malformations. Furthermore, the software allows creating serial curved surfaces in different depths parallel to the cortical surface. This resembles the method of Curvilinear Reformatting as proposed by Bastos et al. (1999) but requires no manual input (e.g., no marking of supporting points on the cortical surface). Moreover, the software includes SISCOM analysis (i.e. subtraction ictal single-photon emission computed tomography (=SPECT) coregistered to MRI), whole brain FLAIR analysis as proposed by Focke N et al. (Epilepsia 2008 and 2009), quantitative FLAIR analysis of temporo-mesial structures (Huppertz HJ et al., Epilepsy Res 2011), automated detection of periventricular nodular heterotopia (PNH) (Pascher B et al., Epilepsia 2013), and tools for visualization of implanted subdural electrodes (Kovalev D et al., AJNR 2005). Recently, a simple volumetric MRI evaluation was added for structures important in epileptology such as hippocampi, cerebral hemispheres, etc.

MAP18 is based on algorithms of the free and open source software for Statistical Parametric Mapping (SPM) of the Wellcome Trust Centre for Human Neuroimaging, UCL Queen Square Institute of Neurology, London, UK, in its current version (SPM12).

Officially, MAP18 is intended for research purposes only and has not been reviewed or approved by the European Medicine Agency (EMA) or by any other agency. Any clinical application of the software is at the sole risk of the party engaged in such application. There is no warranty of any kind that the software will produce useful results in any way. Use of the software is at the recipient's own risk.

WORKSHOP @ SuSIE

Annual Meeting and Summer School on Imaging in Epilepsy, Epilepsy Surgery, Epilepsy Research and Cognitive Neurosciences 2020

(September 14-18, 2020, Bochum, Germany)

When founded in 2015, the Summer School on Imaging in Epilepsy (SuSIE) was a pure teaching event for adult and pediatric epileptologists. Since that time, the SuSIE has undergone continuous further development. It is now a multidisciplinary forum that invites all professions with an interest in development, application, processing and interpretation of neuroimaging for exchange of ideas and experiences. More than any classical congress, SuSIE offers an excellent opportunity to introduce users to new products by hands-on workshops, including MAP18.
