I am a physician specializing in obstetrics and gynecology ultrasound within the Department of Ultrasound at Sun Yat-sen Memorial Hospital, Sun Yat-sen University. I obtained my degree in Medical Imaging from Southern Medical University. With more than ten years of clinical experience in obstetric and gynecological ultrasound diagnostics, I currently conduct a wide range of diagnostic and interventional ultrasound procedures, including routine obstetric and gynecological ultrasound examinations, pelvic floor ultrasound, prenatal ultrasound diagnosis, contrast-enhanced ultrasound, and sonohysterography.
