[ 1 ] - Evaluation of the Efficacy of Standardized Uptake Value (SUV)-shape Scheme for Thyroid Volume Determination in Graves’ Disease: A Comparison with Ultrasonography
Objective(s): In this study, we aimed to evaluate the efficacy of thyroid volume measurement using 99mTc pertechnetate single-photon emission computed tomography (SPECT) images, acquired by the standardized uptake value (SUV)-shape scheme designed by our expert team.Methods: A total of 18 consecutive patients with Graves’ disease (GD) were subjected to both ultrasonographic and 99mTc pertechnet...
[ 2 ] - Background-Based Delineation of Internal Tumor Volumes on Static Positron Emission Tomography in a Phantom Study
Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...
