PURPOSE To assess the added value of true diffusion (D), perfusion factor (f) and apparent diffusion coefficient at low b-values (ADC(low)) for differentiation between liver metastases and hemangiomas based on respiratory-triggered high-resolution Black-Blood Single-Shot SpinEcho Echo Planar Imaging (BB SS SE-EPI). MATERIALS AND METHODS Twenty-five(More)
PURPOSE To prospectively evaluate dose reduction and image quality characteristics of abdominal computed tomographic (CT) scans reconstructed with model-based iterative reconstruction (MBIR) compared with adaptive statistical iterative reconstruction (ASIR) in oncology patients with colorectal liver metastases. MATERIALS AND METHODS The study complied(More)
In this paper, the authors report the results of a genetic-diagnostic survey of 262 instutionalized moderately mentally retarded patients and compare these data with their previous studies of the severely mentally retarded. Special attention is given towards the nosology of X-linked mental retardation and familial mental retardation in general.
The purpose of this study was to compare diffusion-weighted respiratory-triggered single-shot spin echo echoplanar imaging (SS SE-EPI) sequence using four b-values (b = 0, b = 20, b = 300, b = 800 s mm(-2)) and single-shot T2 weighted turbo spin echo (T2W SS TSE) in patients with focal liver lesions, with special interest in small (<10 mm) lesions.(More)
PURPOSE To evaluate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for prediction and early monitoring of treatment in colorectal liver metastases. MATERIALS AND METHODS Ten patients were included. Baseline and follow-up DCE-MRI examinations were evaluated by whole tumour and selected ROI placements calculating Kep-values. Selective ROIs,(More)
PURPOSE To compare lesion conspicuity and image quality between single-shot spin echo echo planar imaging (SS SE-EPI) before, immediately and 5min after intravenous (IV) injection of superparamagnetic iron oxide (SPIO) for detecting and characterizing focal liver lesions (FLLs). MATERIALS AND METHODS Twenty-five patients suspected for colorectal liver(More)
In this report we describe two fra(X) adults and two prepubertal fra(X) brothers with a combination of distinct phenotypic findings: extreme obesity, short stature, stubby hands and feet and diffuse hyper-pigmentation. These clinical abnormalities may be an additional indication of a specific hypothalamic disturbance in the fra(X) syndrome.
PURPOSE To prospectively evaluate a new imaging sequence (4D THRIVE) for whole liver perfusion in high temporal and spatial resolution. Feasibility of parametric mapping and its potential for characterizing focal liver lesions (FLLs) are investigated. MATERIALS AND METHODS Fifteen patients suspected for colorectal liver metastases (LMs) were included.(More)
