Die konventionelle Radiographie, MRT und der HLA-B27-Labortest (HLA: humanes Leukozyten Antigen) spielen eine wichtige Rolle bei Diagnose von axialer Spondyloarthritis (axSpA). Entzündliche fetthaltige Wirbelsäulen- Iliosakralgelenks-MRT-Läsionen sind relativ häufig führen auch zu falsch-positiven Diagnosen. Gründe dafür waren bislang unzureichend erforscht.

Malignant rhabdoid tumor (MRT), originally described as a sarcomatous variant of Wilms' tumor, is now recognized as a distinct, highly malignant entity. The authors describe, for the first time, a primary tumor of the orbit with histologic, immunohistochemical, and ultrastructural features of MRT. Their findings suggest both epithelial and mesenchymal differentiation of this unique tumor.

OBJECTIVES To assess whether there is a correlation between oxygen uptake (VO2) and heart rate (HR) on-kinetics in the constant-load cycle-ergometer test (CLT) and the BODE index and its isolated variables in patients with chronic obstructive pulmonary disease (COPD). METHOD Fourteen male patients between 55 and 78 years of age with moderate to severe COPD were evaluated. Each patient underwe...

Microbeam radiation therapy (MRT) using high doses of synchrotron X-rays can destroy tumours in animal models whilst causing little damage to normal tissues. Determining the spatial distribution of radiation doses delivered during MRT at a microscopic scale is a major challenge. Film and semiconductor dosimetry as well as Monte Carlo methods struggle to provide accurate estimates of dose profil...

Multivariate regression trees (MRT) are a new statistical technique that can be used to explore, describe, and predict relationships between multispecies data and environmental characteristics. MRT forms clusters of sites by repeated splitting of the data, with each split defined by a simple rule based on environmental values. The splits are chosen to minimize the dissimilarity of sites within ...

Ziel: Bestimmung der Wertigkeit der Magnetresonanztomografie (MRT) bei 3T zur Differenzierung zwischen organbegrenztemund kapselüberschreitendem Tumorwachstum beim Prostatakarzinom (PCa). Material und Methoden: Bei 38 konsekutiven Patienten mit histologisch gesichertem PCa erfolgte eine multiparametrische 3-T-MRT-Untersuchung mit endorektaler Spule. Zwei Radiologen mit 9 (A) bzw. 4 (B) Jahren E...

BACKGROUND The relationship between monosymptomatic resting tremor (mRT) and Parkinson's disease (PD) remains controversial. In this study, we aimed to assess the function of presynaptic dopaminergic neurons in patients with mRT by dopamine transporter positron emission tomography (DAT-PET) and to evaluate the utility of clinical features or electrophysiological studies in differential diagnosi...
