UNLABELLED Nuclear medicine plays an important role in the imaging of neuroendocrine tumors (NETs). Somatostatin receptor scintigraphy (SRS) with (111)In-labeled somatostatin receptor analogs is a standard procedure for the detection and staging of NET. Based on the ability of NETs to store biogenic amines, this study evaluated whether 6-(18)F-fluoro-L-DOPA(More)
HYPOTHESIS Single-gland disease identified by preoperative localization studies in combination with rapid intraoperative parathyroid hormone monitoring seems to allow a limited exploration of the neck in sporadic primary hyperparathyroidism. Minimally invasive open parathyroidectomy by lateral approach (oMIP) in sporadic primary hyperparathyroidism seems(More)
PURPOSE To assess the clinical value of computed tomography (CT) and magnetic resonance imaging (MRI) image fusion with 11C-acetate (AC) positron emission tomography (PET) imaging for detection and exact location of clinically occult recurrences. PATIENTS AND METHODS Fifty prostate cancer patients with elevated/increasing serum prostate-specific antigen(More)
UNLABELLED Imaging with radiolabeled somatostatin/vasoactive intestinal peptide analogs has recently been established for the localization diagnosis of a variety of human tumors including neuroendocrine tumors, intestinal adenocarcinomas and lymphomas. This study reports on the biodistribution, safety and radiation absorbed dose of(More)
Based on the fact that somatostatin (SST) analogs have given promising results for treatment of hepatocellular cancer, we performed both in vitro and in vivo investigations to define the role of a depot formulation of the long acting SST-analog lanreotide (LAN). A decrease of cells in the S-phase as compared to controls (p<0.03) followed by a significant,(More)
The high level expression of somatostatin receptors (SSTR) on various tumor cells has provided the molecular basis for successful use of radiolabeled octreotide / lanreotide analogs as tumor tracers in nuclear medicine. Other (nontumoral) potential indications for SSTR scintigraphy are based on an increased lymphocyte binding at sites of inflammatory or(More)
BACKGROUND Monitoring and repeated staging is of substantial importance in many patients with primary cutaneous T-cell lymphomas (CTCL). For primary cutaneous B-cell lymphomas (CBCL), extensive initial staging is the mainstay for correct diagnosis. AIM To evaluate the value of somatostatin receptor scintigraphy using the radiolabeled somatostatin analog(More)
This article presents the well established scintigraphic imaging techniques of the adrenal glands. Both adrenocortical scintigraphy with [131]6beta-iodomethylnorcholesterol (NP-59) and adrenomedullary imaging with 131I or 123I-labelled metaiodobenzylguanidine (MIBG) as function-dependant imaging techniques provide functional metabolic information for lesion(More)
Imaging techniques for first line investigation of diseases of the thyroid gland are sonography (US) and scintigraphy, followed in dedicated cases by magnetic resonance imaging (MRI). Malignant lesions are generally hypoechoic on US with calcifications visible in some cases. The appearance of lymph node metastases is similar to that of the primary tumour.(More)
