The Effect of an Asymmetric Energy Window on Bone Scintigraphy Image Quality

Autor: Stewart Redman, Joana do Mar F Machado, Susan Doshi, Martyn J. Evans, Richard Graham, David Little, Ruth Smith

Publikováno v: Journal of nuclear medicine technology. 48(1)

Purpose: Bone scintigraphy is one of the most common nuclear medicine tests. Previous work investigated the effectiveness of an asymmetric energy window (ASW) for planar bone scintigraphy using simulation and phantom data. Phantom studies concluded t

Effective doses to patients from CT acquisitions on the GE Infinia Hawkeye: a comparison of calculation methods

Autor: Sarah C. Hiscock, Martyn J. Evans, Hazel C. Starritt, Laura J. Sawyer

Publikováno v: Nuclear Medicine Communications. 29:144-149

BACKGROUND Nuclear medicine scans may be accompanied by CT acquisitions to provide localization of radioisotope uptake through image fusion and for use in attenuation correction. The effective doses to patients resulting from radioisotope administrat

Estimated radiation dose to breast feeding infant following maternal administration of 57Co labelled to vitamin B12

Autor: Kay M. Pomeroy, Laura J. Sawyer, Martyn J. Evans

Publikováno v: Nuclear Medicine Communications. 26:839-841

Administration of a radiopharmaceutical may result in a radiation dose to an infant due to ingestion of the radiopharmaceutical secreted in the breast milk. Following a maternal administration of 5 7 Co labelled to vitamin B 1 2 (cyanocobalamin) as p

Use of measured scatter data for the attenuation correction of single photon emission tomography without transmission scanning

Autor: Sarah C, Cade, Simon, Arridge, Martyn J, Evans, Brian F, Hutton

Publikováno v: Medical physics. 40(8)

Attenuation correction is essential for reliable interpretation of emission tomography, however, the use of transmission measurements to generate attenuation maps is limited by availability of equipment and potential mismatches between the transmissi

Investigation of normal ranges for left ventricular ejection fraction in cardiac gated blood pool imaging studies using different processing workstations

Autor: Sarah C. Hiscock, Martyn J. Evans, David O. Hall, Rosemary J. Morton

Publikováno v: Nuclear medicine communications. 29(2)

Background An investigation has been undertaken to calculate normal ranges for left ventricular ejection fraction (LVEF) measured by the gated blood pool (GBP) technique. A common set of normal studies was used at 11 hospitals within the south of Eng

Measurement of Bremsstrahlung as a practical alternative to use of a liquid scintillation counter for the assessment of low activities of 90Y

Autor: Laura J. Sawyer, Sarah C. Hiscock, Martyn J. Evans

Publikováno v: Nuclear medicine communications. 28(8)

Background The use of 90Y for nuclear medicine therapies has steadily increased over the last 10 years. High administered activities are measured in a calibrated re-entrant ionization chamber, while the most sensitive method of assessment of low acti
