Objective:To investigate the clinical application value of dual energy CT photon imaging in the postoperative examination of the patients with cerebrovascular disease by endovascular interventional treatment. Methods:42 cases of cerebrovascular disease from February 2015 to February 2017 in our hospital underwent routine CTA examination and inspection technology of dual energy CT were selected,42 cases of patients underwent endovascular interventional treatment, two kinds of imaging examination results were compared. Results:The grade Ⅰ image quality ratio was 92.86% (39/42) when conventional CTA scanning was done, and the grade Ⅰ image quality ratio of dual energy CT imaging was 88.1% (37/42),the two groups had no significant difference (P>0.05). The radiation dose, scan time and image subtraction time of dual energy CT were (8.54±0.43)mSv, (76.13±5.47)s, (27.59±3.52)s, compared with (11.38±0.78)mSv, (97.07±9.67)s, (48.14±5.12)s in conventional CTA examination,the difference was statistically significant(P<0.05). Conclusion:For the postoperative examination of patients with cerebrovascular disease after interventional therapy, the dual energy CT photon imaging can be taken, the high quality image can be gotten, it is easy to read for radiologists. Compared with the conventional CTA technique, dual energy CT has the lower radiation dose, the shorter scan time, the less injury for patients and it is worthy of clinical promotion. |
