title: High resolution computed tomography. Technical aspects.
abstract: High resolution computed tomography (CT) may be defined as thin section (1-2 mm collimation) CT optimized by using a high-spatial-frequency (bone) algorithm. Further improvement of the image may be obtained by targeting the scan to a small field of view. This article reviews the technical aspects that influence the quality of the CT image as well as some of the scanning protocols used in the assessment of patients who have diffuse lung disease.
