UNLABELLED This study tested the principle that (68)Ga-DOTATATE PET/CT may be used to select children with primary refractory or relapsed high-risk neuroblastoma for treatment with (177)Lu-DOTATATE and evaluated whether this is a viable therapeutic option for those children. METHODS Between 2008 and 2010, 8 children with relapsed or refractory high-risk(More)
UNLABELLED The aim of our study was to evaluate prospectively the diagnostic performance and prognostic significance of (18)F-FDG PET/CT in comparison with (123)I-metaiodobenzylguanidine ((123)I-MIBG) imaging in patients with high-risk neuroblastoma. METHODS Twenty-eight patients with refractory or relapsed high-risk neuroblastoma (16 male and 12 female(More)
Estrogen Therapy (ET) may protect against age-related cognitive decline and neuropsychiatric disorders (e.g. Alzheimer's disease). The biological basis for this putative neuroprotective effect is not fully understood, but may include modulation of cholinergic systems. Cholinergic dysfunction has been implicated in age-related memory impairment and(More)
The mapping of 5-HT2 receptors in the brain using functional imaging techniques has been limited by a relative lack of selective radioligands. Iodine-123 labelled 4-amino-N-[1-[3-(4-fluorophenoxy)propyl]-4-methyl-4-piperidinyl]-5-iodo-2-methoxybenzamide (123I-5-I-R91150 or123I-R93274) is a new ligand for single-photon emission tomography (SPET), with high(More)
UNLABELLED The aim of this study was to examine the safety and efficacy of (186)Re-hydroxyethylidene diphosphonate (HEDP) as an adjuvant to external-beam radiotherapy (EBRT) in the treatment of patients with osteosarcoma. METHODS Thirteen patients (9 male, 4 female; age range, 12-42 y) were treated with combination chemotherapy (standard U.K. protocol)(More)
Technetium-99m-L,L-ethylenedicysteine (99mTc-L,L-EC), a new renal imaging agent, was introduced as an alternative to99mTc-mercaptoacetyltriglycine (MAG3). This radiopharmaceutical can be easily labelled at room temperature and has high radiochemical purity and long stability. The aim of this study was to gain clinical experience in using99mTc-L,L-EC in(More)

Iodine-123 labelled 4-amino-N-[1-[3-(4-fluorophenoxy)propyl]-4-methyl-4-piperidinyl]-5-io do-2-methoxybenzamide (123I-5-I-R91150 or 123I-R93274) is a new ligand for single-photon emission tomography (SPET), with high(More)
INTRODUCTION A three-dimensional model-based resolution recovery (RR) reconstruction algorithm that compensates for collimator-detector response, resulting in an improvement in reconstructed spatial resolution and signal-to-noise ratio of single-photon emission computed tomography (SPECT) images, was tested. The software is said to retain image quality even(More)
