Abstract

Abstract:

Objective

To study the value of radiation protection by low dose scanning technique of spectral CT in patients with acute cerebral trauma.

Methods

31 cases who underwent CT scan of head due to cerebral trauma were selected from October 2015 to December 2015 in 2nd hospital of Shanxi medical university. The image by low dose scanning was obtained as the observation group, and in contrast the routine CT scan was the control group. Date of effective dose(ED) and the image quality score by CT scan were recorded and compared using self-control study.

Results

The ED of observation group was less than the control group which reduced 50%, and there was a significant difference between them(t=4.23, P<0.05). As for the image quality score, There was no significant difference between two groups(t=0.38, P>0.05).

Couclusion

Spectral CT low dose scanning technology can be applied to the patients, head scan when suffered acute brain trauma, not only the image quality meet the clinical diagnosis, but also can effectively reduce the radiation dose of patients with repeated examination.

Key words: Energy spectrum CT, Low dose scanning, Radiation protection
