Abstract：Objective: To explore the application value of color doppler flow imaging in evaluating the drug therapeutic response of arterial erectile dysfunction (ED). Methods: Twenty patients with arterial ED were requested to take Phosphodiesterase type-5 (PDE5) inhibitor quarter grain every day before sleeping for six weeks. All the patients were Pre- and post - treatmenlyt scored on international index of erectile function (IIEF-5) and received intracaverous injection of vasoactive agent, followed by measurement of peak systolic velocity (PSV) of cavernosal artery by color doppler ultrasound. Results: The IIEF-5 score (20.80 ± 2.70), left PSV (35.50 ± 9.12) m/s and right PSV (33.45 ± 9.19) m/s of post-treatment group were significantly higher than the IIEF-5 score (10.20 ± 2.35), left PSV (18.35 ± 3.54) m/s and right PSV (16.35 ± 3.94) m/s of pretherapy group (P<0.05). Conclusion: Color doppler flow imaging is one of the effective method of evaluating the therapeutic response of arterial ED.
