OBJECTIVES computed tomography (CT) is considered the method of choice in thoracic imaging for a variety of indications. Sedation is usually necessary to enable CT and to avoid deterioration of image quality because of patient movement in small children. We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the need of sedation and to hold the breath. MATERIAL AND METHODS a total of 60 patients were included in this study. 30 patients (mean age, 14 ± 17 month; range, 0-55… CONTINUE READING
