Quantitative Measurements Versus Receiver Operating ...
RATIONALE AND OBJECTIVES: This study aimed to evaluate the correlation of quantitative measurements with visual grading regression (VGR) and receiver operating characteristics (ROC) analysis in computed tomography (CT) images reconstructed with iterative reconstruction. MATERIALS AND METHODS: CT scans on a liver phantom were performed on CT ......
Analytical image reconstruction methods in emission tomography
The reconstruction methods are divided into analytic and iterative approaches, each one presenting its own advantages and limitations. The choice of one or the other depends basically on the clinical objective of the study and the computational facilities supplied by the imaging system manufacturers.
Standardized Uptake Value Using Thyroid Quantitative SPECT ...
The clinical applications of the quantitative single photon emission computed tomography (SPECT)/computed tomography (CT) are being expanded to a variety of fields of nuclear medicine. However, clinical application of quantitative SPECT/CT for the evaluation of Graves’ disease (GD) still needs further investigation. Our aim was to investigate the feasibility of standard uptake value (SUV) of ...
