Table 2 Self-assessment Likert scale responses for the experiential education group and the control group

From: Constructing an experiential education model in undergraduate radiology education by the utilization of the picture archiving and communication system (PACS)

Likert scale questions experiential education group* control group* Significance level (p value)
1. I am familiar with the basic functions and operations of the DICOM viewer software. 3.35 ± 0.10 2.30 ± 0.12 < 0.001
2. I am familiar with the basic CT scanning sequences. 3.60 ± 0.11 2.64 ± 0.14 < 0.001
3. I am familiar with the reading sequence of CT imaging. 3.35 ± 0.11 2.55 ± 0.14 < 0.001
4. I am familiar with the reconstruction methods of CT images. 3.48 ± 0.15 2.85 ± 0.15 < 0.001
5. I clearly understand how to adjust the proper window width and window level for observation. 3.50 ± 0.12 3.38 ± 0.11 0.004
6. I am familiar with the density of different tissue to choose an appropriate window width and window level. 3.55 ± 0.10 3.15 ± 0.11 NS
7. I am familiar with the location of different organs in the cross section. 3.38 ± 0.10 3.17 ± 0.12 0.016
8. I am familiar with the relative location of different organs, and I can reconstruct them in my mind. 3.20 ± 0.12 2.77 ± 0.13 NS
9. I have confidence in reading the CT images in the internship. 4.35 ± 0.10 3.89 ± 0.14 0.047
10. I agree that using the DICOM viewer can be helpful for learning clinical imaging. 4.18 ± 0.10 3.94 ± 0.13 0.024
11. I am interested in radiology. 3.23 ± 0.17 3.15 ± 0.11 NS
12. I think I may become a radiologist. 2.95 ± 0.13 2.85 ± 0.13 NS
  1. NS not statistically significant
  2. * The average score was calculated by the following valuation: strongly agree = 5; agree = 4; neutral = 3; disagree = 2; strongly disagree = 1
