ABSTRACT
Our aim was to study the scan protocol of 16 DAS (Data Acquisition System) multidetector-row CT (MDCT) and to ascertain whether we could reduce radiation exposure and scanning time, while maintaing image quality in the Virtual endoscopy (VE).We made a mimic gastrointestinal tract and examined the result by changing a scan protocol of 16 DAS MDCT.We found that a reduction of radiation exposure and scanning time depended on slice width, angle of the table, rotation time, table speed, mAs/slice and resolution.The study confirmed that it was possible to use the scan protocol of MDCT with a radiographic dose of 40% and scanning time of 50%, without changing image quality in the VE.
