Chest CT images were reconstructed using high matrix (1024 \u00d7 1024) or standard matrix (512 \u00d7 512), with all other parameters matched. Two radiologists, blinded to reconstruction technique, independently examined each lung, viewing image sets side by side and rating the conspicuity of imaging findings using a 5-point relative conspicuity scale. The presence of pulmonary nodules and confidence in classification of internal attenuation was also graded. Overall image quality and subjective noise\/artifacts were assessed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>Thirty-four patients with 68 lungs were evaluated. Relative conspicuity scores were significantly higher using high matrix image reconstruction for all imaging findings indicative of idiopathic lung fibrosis (peripheral airway visualization, interlobular septal thickening, intralobular reticular opacity, and end-stage fibrotic change; <jats:italic>P<\/jats:italic> \u2264 0.001) along with emphysema, mosaic attenuation, and fourth order bronchi for both readers (<jats:italic>P<\/jats:italic> \u2264 0.001). High matrix reconstruction did not improve confidence in the presence or classification of internal nodule attenuation for either reader. Overall image quality was increased but not subjective noise\/artifacts with high matrix image reconstruction for both readers (<jats:italic>P<\/jats:italic> &lt;
