PURPOSE While influx of chemoembolic agents into the hepatic falciform artery (HFA) from the hepatic artery can cause supraumbilical skin rash, epigastric pain and even skin necrosis, the significance of a patent HFA in patients undergoing radioembolization is not completely clear. Furthermore, the presence of tracer in the anterior abdominal wall seen in(More)
PURPOSE In patients with drug-refractory focal epilepsy, nonlesional magnetic resonance imaging (MRI) or discordant data of presurgical standard investigations leads to failure generating a sufficient hypothesis for electrode implantation or epilepsy surgery. The seizure-onset zone can be further investigated by subtraction ictal single-photon emission(More)
OBJECTIVE To identify biological evidence for Alzheimer disease (AD) in individuals with subjective memory impairment (SMI) and unimpaired cognitive performance and to investigate the longitudinal cognitive course in these subjects. METHOD [¹⁸F]fluoro-2-deoxyglucose PET (FDG-PET) and structural MRI were acquired in 31 subjects with SMI and 56 controls.(More)
PURPOSE The medical treatment of metastatic medullary thyroid carcinoma (MTC) is still questionable. The aim of this study was to evaluate a combined imaging protocol using 111In-DTPA-octreotide and 131I/123I-MIBG to decide whether targeted radiotherapy would be useful, and which radiopharmaceutical (90Y-DOTATOC or 131I-MIBG) would be more effective.

UNLABELLED Several radiopharmaceuticals and imaging techniques are proposed for breast cancer imaging. Since limited data are available of the uptake of SPECT and PET radiopharmaceuticals in malignant breast tumors and their metastases the aim of this study was to compare the uptake values and to correlate these data with imaging findings. METHODS We have(More)
BACKGROUND Assessing whether an association exists between drainage to multiple basins and lymphatic metastasis in patients with truncal melanoma (TM). METHODS The study included 260 patients with primary TM (163 men; median age 56.5 y/o) with a cN0 M0, who underwent a sentinel lymph node scintigraphy and biopsy. The median tumor thickness (TT) was 1.51(More)
OBJECTIVE To evaluate the effect of 90Y-DOTATOC and 131I-MIBG in treatment of metastatic medullary thyroid carcinoma (MTC). METHODS Twelve histologically confirmed patients with metastatic MTC were included. All patients underwent both 111In-DTPA-octreotide imaging and 131I/ 123I-meta-iodobenzylguanidine (MIBG) imaging. According to the results of the(More)
PURPOSE Lobar radioembolization (RE) of the liver can result in reduction in volume of the ipsilateral lobe as well as hypertrophy of the contralateral lobe. Theoretically, hypertrophy of the contralateral liver lobe after RE could increase the chance of a successful liver resection, especially in patients with limited liver function reserve. The aim of(More)
Increased articular 99mTc MDP uptake on blood pool imaging (BPI) of patients with rheumatologic conditions is indicative of active inflammatory changes, and has been suggested as a strong predictor of response to radiosynoviorthesis (RSO). In this study, we aimed to assess the value of pretreatment BPI positivity (i.e. scintigraphic-apparent hyperemia) for(More)
