RATIONALE AND OBJECTIVES Magnetic resonance imaging (MRI)-based texture analysis has been shown to be effective in classifying multiple sclerosis lesions. Regarding the clinical use of texture analysis in multiple sclerosis, our intention was to show which parts of the analysis are sensitive to slight changes in textural data acquisition and which steps(More)
BACKGROUND Our objective was to study the effect of trauma on texture features in cerebral tissue in mild traumatic brain injury (MTBI). Our hypothesis was that a mild trauma may cause microstructural changes, which are not necessarily perceptible by visual inspection but could be detected with texture analysis (TA). METHODS We imaged 42 MTBI patients by(More)
BACKGROUND To show magnetic resonance imaging (MRI) texture appearance change in non-Hodgkin lymphoma (NHL) during treatment with response controlled by quantitative volume analysis. METHODS A total of 19 patients having NHL with an evaluable lymphoma lesion were scanned at three imaging timepoints with 1.5T device during clinical treatment evaluation.(More)
BACKGROUND The accuracy of texture analysis in clinical evaluation of magnetic resonance images depends considerably on imaging arrangements and various image quality parameters. In this paper, we study the effect of slice thickness on brain tissue texture analysis using a statistical approach and classification of T1-weighted images of clinically confirmed(More)
RATIONALE AND OBJECTIVES The aim of this study was to evaluate whether texture analysis (TA) can detect subtle changes in cerebral tissue caused by mild traumatic brain injury (MTBI) and to determine whether these changes correlate with neuropsychological and diffusion tensor imaging (DTI) findings. MATERIALS AND METHODS Forty-two patients with MTBIs were(More)
OBJECTIVE We describe the essential diffusion tensor imaging (DTI) findings of right cerebral hemisphere infarctions and study whether the DTI parameters and neurological status differ in patients with visible wallerian degeneration (WD) or small hemorrhagic transformation (HT) in the chronic stage. METHODS Twenty-five stroke patients underwent DTI.(More)
A sample of 3278 students (aged 15-16 years) were surveyed to investigate the interrelations between depression (RBDI; The Finnish modification of the 13-item Beck Depression Inventory), antisocial behaviour (YSR; Youth Self-Report) and perceived social support from family, friends and significant other (PSSS-R; the Perceived Social Support Scale-Revised).(More)
The aim here is to show that texture parameters of magnetic resonance imaging (MRI) data changes in lymphoma tissue during chemotherapy. Ten patients having non-Hodgkin lymphoma masses in the abdomen were imaged for chemotherapy response evaluation three consecutive times. The analysis was performed with MaZda texture analysis (TA) application. The best(More)
OBJECTIVE To evaluate the use of web-based patient education sessions in the psychiatric inpatient care. METHODS The qualitative and quantitative data was collected from 93 patients' evaluation reports in two psychiatric hospitals in Finland completed by 83 nurses. RESULTS The web-education included six patient education sessions which were used over a(More)
Iron is an essential trace element whose absorption is usually tightly regulated in the duodenum. HFE-related hereditary hemochromatosis (HH) is characterized by abnormally low expression of the iron-regulatory hormone, hepcidin, which results in increased iron absorption. The liver is crucial for iron homeostasis as it is the main production site of(More)
