Abstract
Objective: to carried out the comparison of the data of MDCT of the patients, undergoing screening using the standard protocol MDCT aortography and FLASH “fast” protocol of scanning. It is discussed the possibility of the reduction of the injected amount of the contrast agent for “fast” aortography.
Materials and methods. The aorta examinations of 101 patients (69 men (68%) and 32 women (32%); the average age ± the standard deviation – 56.34 ± 11.5 years) were analyzed. The examinations have been carried out on MDCT with two sources of Х-ray (DSCT); 48 patients have been undergone the examination using “fast” FLASH scanning. It has been compared the scanning time, the length of the examination zone and ED (Effective Dose) load calculated for the groups for the standard and “fast” MDCT aortography.
Results. CDTIvol and DLP values were statistically proved lower (p < 0.001) at the examination of the patients that had been undergone “fast” protocol of scanning FLASH. The average ED was considerably lower in this group of the patients in comparison with the patients that had been examined using standard protocol (4.36 ± 1.69 mSv and 15.12 ± 4.62 mSv, р < 0.001). Without the reliable difference in the length of the examination zone in groups (42.91 ± 3.23 cm and 43.68 ± 2.66 cm, p = 0.55), the duration of the examination of MDCT aorta was considerably lower in the second group (9.29 ± 0.85s and 1.93 ± 0.12 s, p < 0.001).
Conclusion. The method of the superfast aorta МDCT make it possible to reduce ED and the amount of the injected contrast agent at the examination of the vast zone. At the same time, qualitative and quantitative analysis of the MDCT remains high.
