- W2592722118 abstract "Abstract Introduction The aim of this study was to compare the image quality obtained using low‐dose and standard‐dose 320‐row temporal bone computed tomography ( CT ) in paediatric patients. Methods Thirteen low‐dose CT (120 kV /50 mA s) and nine standard‐dose CT (120 kV /100 mA s) images from children up to 5 years of age were compared for their image quality. The noise and signal‐to‐noise ratio for bone, fat and air were measured. Two observers assessed the overall image quality and ability to visualize 14 small anatomic structures using a 5‐point scale, with a score of 3–5 indicating imaging of diagnostic quality. Results Noise was significantly higher and the signal‐to‐noise ratio was significantly lower with low‐dose CT . Although the overall image quality and visibility of several structures on low‐dose CT were significantly reduced when compared with standard‐dose CT , all the image quality scores were 3 or >3. The dose‐length products for low‐dose CT and standard‐dose CT were 59.6 mG y·cm and 119.3 mG y·cm, respectively. Conclusion Low‐dose CT of the temporal bone using 320‐row CT provides images of diagnostic quality for assessment of middle and inner ear anatomy, similar to that provided by the standard‐dose protocol, in spite of increased image noise." @default.
