The aim of this study was to establish a nerve lesion model to compare serial electrophysiological and functional outcome measures with histological findings. The relative significance of the parameters in lesions of diverse severity, the time course of recovery, and the tools for serial longitudinal studies after nerve lesions were studied in rats. We(More)
Purpose: 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) is currently not used on a routine basis for imaging of neuroendocrine (NE) tumors. The aim of this study was to investigate the prognostic value of FDG-PET in patients with NE tumors. Experimental Design: Ninety-eight prospectively enrolled patients with NE tumors underwent FDG-PET(More)
BACKGROUND In animal studies tumor size is used to assess responses to anticancer therapy. Current standard for volumetric measurement of xenografted tumors is by external caliper, a method often affected by error. The aim of the present study was to evaluate if microCT gives more accurate and reproducible measures of tumor size in mice compared with(More)
UNLABELLED Functional techniques are playing a pivotal role in the imaging of cancer today. Our aim was to compare, on a head-to-head basis, 3 functional imaging techniques in patients with histologically verified neuroendocrine tumors: somatostatin receptor scintigraphy (SRS) with (111)In-diethylenetriaminepentaacetic acid-octreotide, scintigraphy with(More)

AIM To study whether (18)F-FDG can be used for in vivo imaging of atherogenesis by examining the correlation between (18)F-FDG uptake and gene expression of key molecular markers of atherosclerosis in apoE(-/-) mice. METHODS Nine groups of apoE(-/-) mice were given normal chow or high-fat diet. At different time-points, (18)F-FDG PET/contrast-enhanced CT(More)
AIM To measure, by a quantitative approach, the gene expression underlying the results of somatostatin receptor (sst) scintigraphy ((111)In-DTPA-octreotide) and noradrenaline transporter (NAT) scintigraphy ((123)I-MIBG) in patients with neuroendocrine (NE) tumors. METHODS The gene expression of somatostatin receptors 1-5 (sst) and NAT was measured(More)
BACKGROUND The aim of this study was to assess the diagnostic and therapeutic impact of preoperative positron emission tomography and computed tomography (PET/CT) in the initial staging of patients with early-stage breast cancer. PATIENTS AND METHODS A total of 103 consecutive patients with newly diagnosed operable breast cancer with tumors ≥2 cm were(More)
Invasive cancer causes a change in density in the affected tissue, which can be visualized by x-ray phase-contrast tomography. However, the diagnostic value of this method has so far not been investigated in detail. Therefore, the purpose of this study was, in a blinded manner, to investigate whether malignancy could be revealed by non-invasive x-ray(More)
Expression of miRNAs in Neuroendocrine Neoplasms (NEN) is poorly characterized. We therefore wanted to examine the miRNA expression in Neuroendocrine Tumors (NETs), and identify their targets and importance in NET carcinogenesis. miRNA expression in six NEN primary tumors, six NEN metastases and four normal intestinal tissues was characterized using miRNA(More)
