Results
Total of 123 patients were included in the study,
74 females and 49 males.
Average age was 62 years (range 19-68 years).
Before DCT 87%(74/85) of coronary CTA studies were done using retrospective helical mode compared to 10%(4/38) after DCT (p=0.000).
After DCT ECG triggered prospective high-pitch helical and prospective axial modes were used in 58%(22/38) and 32%(12/38),
respectively,
compared to 7%(6/85) and 6%(5/85) before the training.
This resulted in a significant patient dose reduction: average DLP in the group before DCT was 914.53mGycm (SD=619.1; range 84-3754mGycm) compared to 172.32mGycm(SD=115.9; range 57-505mGycm) in the group after DCT (p=0.000).
There were no significant differences in average calcium score between the groups (188.34 and 125.91,
respectively,
p=0.338).
