DTS was performed with GE Definium8000 (March 2011–April 2016, n = 45) and GE DiscoveryXR656 (May 2016–February 2017, n = 17) equipment with the VolumeRAD option (GE Healthcare). A frontal CXR was used as a scout, and imaging parameters for DTS was according to recommended standard settings.(28 (link)) Approximately 60 low-dose projections were acquired during a 10s breath hold, in standing position at full inspiration during a caudocranial tube movement ±15° from the standard postero-anterior direction. Tube voltage was 120–125 kV and additional filtration were 3 mm aluminium and 0.1 mm copper. The examination also included a lateral CXR. The low-dose projections were reconstructed to ~60 section images in the coronal plane, with a slice interval of 5 mm. No retakes were allowed because of radiation considerations.

The Regional Ethical Review Board approved this study and all participants gave written informed consent. Pathologyfree CTS examinations from twenty-four patients (male, n = 14), with age between 22 and 77 years (average 49.9 years) were included in the study. Some of the included examinations have previously been used in CTS studies with other purpose (10, 15) . The CTS examinations were performed using GE Definium 8000 with VolumeRAD option (GE Healthcare, Chalfont St Giles, UK). For each examination, sixty low-dose projection images were collected within an angular interval of §15°around the posteroanterior (PA) projection. The projection images were collected using a tube voltage of 120 kV and an additional filtration of 3 mm Al + 0.1 mm Cu and the image acquisition time was approximately 10 seconds. The tube load (mAs) used for the collection of each projection image was determined from a PA scout image, which was collected using automatic exposure control and the dose ratio 1:10. These default exposure settings results in an effective dose of 0.12 mSv (0.13 mSv scout view included) for an average-sized patient (3).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
