BACKGROUND While most patients with depression respond to combinations of pharmacotherapy, psychotherapy, and electroconvulsive therapy (ECT), there are patients requiring other treatments. Deep brain stimulation (DBS) allows modulation of brain regions that are dysfunctional in depression. Since anhedonia is a feature of depression and there is evidence of(More)
PURPOSE The combination of positron emission tomography (PET) and magnetic resonance (MR) tomography in a single device is anticipated to be the next step following PET/CT for future molecular imaging application. Compared to CT, the main advantages of MR are versatile soft tissue contrast and its capability to acquire functional information without(More)
OBJECTIVES Detection of disease activity in Crohn's disease (CD) is of crucial importance for diagnosis and management of the disease. Noninvasive methods for monitoring are desirable and comprise hydromagnetic resonance imaging (hydro-MRI) and leukocyte scintigraphy. In addition, a recent case report indicated the potential of 18F-fluorodeoxyglucose(More)
PURPOSE The role of the Ki-67 tumour proliferation index (PI) in predicting the efficacy of peptide receptor radionuclide therapy (PRRT) in gastroenteropancreatic tumours (GEP-NET) remains undetermined. This single-centre analysis focused on the potential therapeutic impact of this immunohistochemical parameter. METHODS A total of 81 consecutive GEP-NET(More)
UNLABELLED Selective internal radiation therapy (SIRT), a catheter-based liver-directed modality for treating primary and metastatic liver cancer, requires appropriate planning to maximize its therapeutic response and minimize its side effects. (99m)Tc-macroaggregated albumin (MAA) scanning should precede the therapy to detect any extrahepatic shunting to(More)
FSH plays a central role in normal reproductive function, i.e. control of follicular maturation in the female and initiation and maintenance of spermatogenesis in the male. The effects of FSH are mediated by its interaction with a specific receptor that belongs to the superfamily of guanine nucleotide-binding protein-coupled receptors. Due to the(More)
Proteinase-3 (PR-3) is a neutral serine proteinase present in azurophil granules of human polymorphonuclear leukocytes and serves as the major target antigen of antineutrophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA) in Wegener's granulomatosis (WG). The WG disease appears as severe vasculitis in different organs (e.g. kidney,(More)
PURPOSE The aim of this study was to evaluate the feasibility of applying a previously described dose strategy based on (99m)Tc-pertechnetate thyroid uptake under thyrotropin suppression (TcTU(s)) to radioiodine therapy for unifocal thyroid autonomy. METHODS A total of 425 consecutive patients (302 females, 123 males; age 63.1+/-10.3 years) with unifocal(More)
Neuroimaging studies in major depressive disorder (MDD) have indicated dysregulation in a network involving prefrontal cortex, subgenual cingulate and the amygdalae, which is known to be modulated by serotonin. The serotonergic system is the principal target for pharmacological treatment in MDD and the functional variable serotonin promoter polymorphism(More)
Alterations of regional cerebral blood flow (rCBF) in prefrontal cortex and the anterior cingulate cortex are conspicuous imaging findings in patients with major depression (MD). While these rCBF changes have been suggested as functional disease markers, data in large patient samples examining treatment response prediction to antidepressant therapy are(More)
