Introduction Low tube voltage allows for computed tomography (CT) imaging with increased iodine contrast at reduced radiation dose. We sought to evaluate the image quality and potential dose reduction using a combination of attenuation based tube current modulation (TCM) and automated tube voltage adaptation (TVA) between 100 and 120 kV in CT of the head and neck. Methods One hundred thirty consecutive...
To evaluate an automated attenuation-based kV-selection in computed tomography of the chest in respect to radiation dose and image quality, compared to a standard 120kV protocol.104 patients were examined using a 128-slice scanner. Fifty examinations (58±15 years, study group) were performed using the automated adaption of tube potential (100–140kV), based on the attenuation profile of the scout scan,...
