Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...

The OECD Workshops on the Economics of the Information Society are aimed at developing economic data, research and analysis under the aegis and direction of the ICCP Committee as the precursor for policy discussions within the Committee. The workshops will concentrate on providing leading edge research on the economics of the coming "information society", will have a quantitative and empirical ...

INTRODUCTION Particle-emitting, bone-seeking radiopharmaceuticals have attracted the attention of the nuclear medicine community over the last three decades for the treatment of the pain of osteoblastic metastases. The objectives of this research were to produce quality-controlled (159)Gd-EDTMP in order to provide a new therapeutic radiopharmaceutical for use in clinical applications. METHODS...

The (158)Gd(n,γ)(159)Gd reaction was studied at 12 isolated neutron resonances by the TOF method at the IBR-30 Fast Pulse Reactor at JINR Dubna. Totally 15 secondary γ transitions in (159)Gd were recorded in the range from 450 keV to 750 keV. Of these, six previously unseen transitions were placed on the established (159)Gd level scheme. The depopulation of strongly populated levels at 507.7 ke...

Maximal ground-state deformation should occur when both proton and neutron Fermi surfaces are located at midshell. However, subshell gaps that stabilize large can exist or values other than One such gap may $Z=60$ in the rare-earth region, as energy of first ${2}^{+}$ states even-even nuclei often lowest an isotonic chain for neodymium ($Z=60$) rather midshell isotopes dysprosium ($Z=66$). Furt...

INTRODUCTION Gender dysphoria (GD) is a condition in which there is a marked incongruence between an individual's psychological perception of his/her sex and their biological phenotype. Gender identity disorder was officially renamed "gender dysphoria" in the DSM-V in 2013. The prevalence and demographics of GD vary according to geographical location and has not been well-documented in Ireland....

two new potential magnetic resonance imaging contrast agents, gd-hematoporphyrin (gd-h) and gd-tetra-carboranylmethoxyphenyl-porphyrin (gd tcp), were synthesized and applied to nude mice with human melanoma (mm 138) xenografts. these agents showed a high relaxivity because of their greater potential to coordinate water molecules. the reduction of t1 relaxation times of 16 and 21% was observed i...
