[Structural MRI investigation in schizophrenia with optimised voxel-based morphometry--a pilot study]. / Strukturális MR-vizsgálat szkizofréniában optimalizált voxel-alapú morfometriával.

The quantitative and structural MRI methods have an emergent role in the fields of psychiatric disorders. In our paper we present voxel-based morphometry, which is the most frequently used structural MRI method. We compared eight patients with schizophrenia and eight, age-matched healthy subjects to detect focal tissue differences in gray and white matter, and cerebrospinal fluids between the two groups. As with earlier studies, patients with schizophrenia showed decreased gray matter tissue density in frontotemporal and insular regions bilaterally. Moreover, the left-sided parietal operculum and the calcarina showed focal decrease in tissue density. Density decrease in the frontotemporal and insular white matter was detected bilaterally, which was similar to gray matter changes. The left sided precuneus and lingual gyrus were also involved in reduced white matter density. Increased cerebrospinal fluid spaces were detected in the frontal regions and the ventricles. Our results with the optimised voxel-based morphometry are in line with earlier imaging studies and correspond with neuropsychological detectable frontotemporal deficits in schizophrenia.
