dc.description.abstractPurpose: To verify if the mAs and reconstruction techniques affect the visualization of relevant structures in lung Computed Tomography (CT) using a phantom. Methods and Materials: Images were acquired using varying mAs and reconstruction techniques. Image quality (IQ) was analyzed applying two approaches: perceptual, using 5 observers and objective (edge gradient calculation) to verify the sharpness of the structures. Dose was recorded. Wilcoxon Signed Rank test was used to compare the data from the perceptual image analysis. P-values were calculated (Bonferroni-Correction method) to compare reconstruction techniques and mAs. A Kappa Test with linear weighting was performed to calculate the level of agreement between observers.pt_PT
