Abstract:
Objective To investigate the diagnostic potential of low-dose computed tomography angiography(CTA)and global biomimetic three-dimensional model reconstruction technology in patients with arterial erectile dysfunction(ED).Methods A total of 136 patients with ED were selected.Digital subtraction angiography(DSA)was performed on all patients as per their treatment requirements and conditions,following ultrasound and CTA examination,and 75 patients finally completed DSA examination.All patients with International Index for Erectile Function(IIEF5)score ranged from 1 to 20.All patients received immediate ultrasound monitoring after injection of alprostadil 10 μg and underwent CTA examination.DSA was conducted at a minimum interval of 72 h.The global biomimetic three-dimensional model tool was used to reconstruct the CTA data and evaluate the stenosis of the pudendal vessels.The diagnostic efficacy of CTA examination,ultrasound and DSA examination were compared and calculated.Results A total of 1 632 vessels were evaluated in 136 patients,including 155 stenoses.DSA was performed in 75 patients.A total of 900 vessels were evaluated,of which 88 were stenoses.Compared with the results of CTA,ultrasound and DSA,the average stenosis scores of all measured vessels were not statistically significant(P＜0.05).The correlation between CTA and ultrasound(r2=0.939 9,P＜0.000 1)and DSA(r2=0.944 0,P＜0.000 1)in the evaluation of vascular stenosis were good,and the diagnostic consistency was consistent.Conclusion Low-dose CTA and global biomimetic three-dimensional model reconstruction technology can effectively diagnose pudendal artery stenosis,and can perform all-round reconstruction observation,which is worthy of further clinical application.
