BACKGROUND We aimed to test the ability of texture analysis to differentiate the spatial heterogeneity of (125)I-A5B7 anti-carcinoembryonic antigen antibody distribution by nano-single photon emission computed tomography (SPECT) in well-differentiated (SW1222) and poorly differentiated (LS174T) hepatic metastatic colorectal cancer models before and after(More)
OBJECTIVE Tissue accumulation of (18)F-FDG is quantified as standardised uptake value (SUV), which may be expressed as the voxel maximum (SUVmax) or mean (SUVmean). SUVmax/SUVmean may be a marker of hepatic steatosis, while the coefficient of variation (CV) of SUV may be a marker of hepatic fat distribution heterogeneity (HFDH). Alternatively, they may(More)
SUMMARY This study showed that regional bone blood flow and (18)F-fluoride bone plasma clearance measured by positron emission tomography are three times lower at the hip than the lumbar spine. INTRODUCTION Measurements of effective bone plasma flow (K (1)), bone plasma clearance (K ( i )) and standardised uptake values (SUV) using (18)F-fluoride positron(More)
UNLABELLED We assessed the precision of lumbar spine (18)F-PET measurements based on 58 scans performed on 20 postmenopausal women. The percentage coefficient of variation (%CV) (95% confidence interval) was 9.2% (7.5-11.8) for standardised uptake values, 11.7% (9.5-14.9) for plasma clearance measurements using the Patlak method and 14.5% (11.7-18.5) for(More)
UNLABELLED The aim of this study was to examine the effects of bisphosphonate discontinuation on bone metabolism at the spine and hip measured using (18) F-fluoride PET. Bone metabolism at the spine remained stable following discontinuation of alendronate and risedronate at 1 year but increased in the hip in the alendronate group only. INTRODUCTION(More)
Aim The purpose of our study was to evaluate the role of CT-based body composition measurements in predicting clinical outcomes in patients with operable oesophageal cancer. Methods A total of 123 patients who had baseline whole-body 18F-FDG PET/CT scans and underwent NACT followed by surgery for oesophageal cancer were included. Mor-phometric parameters(More)
