Cím:Sapital standardisation of RCBF-SPECT in early dementia patients and healthy control subjects / T. Györke, P. Barsi, T. Kovács, I. Gyuricza, B. Kári, K. Karlinger, G. Balázs, G. Opposits, L. Trón, M. Emri
Megjegyzések:Aim: In order to perform population level statistical analysis (SPM) of rcbf-SPECT in early dementia we investigated the reliability of spatial standardisation (SS). Material and methods: SPECT and T1 weighted MRI investigations of 15 patients with early dementia and 11 healthy subjects were used. SS based on MRI and based only on SPECT data were compared using the statistical comparisons of the perfusion distributions measured in the same location of the brain. These areas were delineated in healthy regions with digital brain atlas software. For registration free of charge or commercially available and own developed softwares were applied. Results: We have shown that the MR based SS is more accurate than the SPECT based one. However the SPECT based SS offers good input for the population level SPM analysis. In the case of severely hypo-perfused areas the MRI images are indispensable. Conclusion: With the above limitations SPECT based SS proved to be reliable enough in this study population for the population level SPM analysis.

Cím:Experience with DICOM base multimodality medical image processing at the PET Center of the University of Debrecen / G. Opposits, M. Emri, P. Barsi, P. Bogner, O. Ésik, J. Julow, M. Kiss, J. Kollár, J. Martos, L. Trón
Megjegyzések:Background: Digital radiology ensures the possibility to process images recorded by different modalities in the same way and transmit them via the internet. This intention is facilitated by DICOM standard whose implementations may be very different. Material and methods: To overcome the problems arising from this variegation, we decided to supplement the software library developed at our department with a DICOM implementation. This allows for the identical data procession of files from national and international partners alike. Results: We routinely use CT and MRI data files in daily diagnostics as well as in the spatial standardization of brain activation examinations. Images and contours are transmitted in DICOM format to support the planning of irradiation. After the spring of 2005, all of the Debrecen patients will be given their PET images in DICOM for- mat. Conclusion: We have been given an opportunity to start methodological develo- pment in the field of cardiological image processing through the wider implementa- tion of DICOM standard.
