| description | To explore the feasibility of optimized scan protocol in whole-brain vessel one-stop examination with 640-multislice computed tomography (640-MSCT) scanner.
A total of 28 patients undergoing whole-brain vessel examination but showing no obvious cerebral disease with 640-MSCT scanner between September 2012 and May 2013 were collected and divided into two groups of A (n = 14) and B (n = 14) . The recommended scan protocol (protocol 1: collecting 19 volumes) was applied in A group while the optimized scan protocol (protocol 2: collecting 15 volumes) formulated by reducing scanning phases reasonably and changing collection intervals in B group. The dose length product (DLP) was recorded automatically and effective dose (E) measured. The CT perfusion (CTP) values and computed tomographic angiography (CTA) images were analyzed for both groups. The regions of interest (ROI) of CTP images with area (20 ± 2) mm² were located in bilateral frontal white matter, parietal white matter, centrum semiovate, basal ganglia, oc |
