Ultrasound

The Department of Ultrasound with a staff of 15 including 1 chief physician, 4 associate- chief physician ,4 assistants, and 5 postgraduates, is the provincial center of ultrasonic diagnosis in obstetrics and gynecology. It is equipped with advanced color doppler ultrasonic diagnosis systems, such as Aspen Acuson, 128-xp and Medsion 530D which can display three-dimensional ultrasonic images. The department plays an important role in the diagnosis of gynecologic diseases. It provides important information for detecting and characterizing pelvic masses of uterine, ovarian, or adnexal origin and the criteria for determining their benign or malignant nature through color doppler ultrasonic diagnosis system . In cases of patients with abnormal bleeding, transvaginal ultrasound helps in determining the presence of morphological and structural changes of the endometrium. In suspected ectopic pregnancy, ultrasound can be used to guide the diagnosis. Ultrasound also plays an important role in the treatment of female infertility. It can be used to diagnose the cause of infertility, monitor cyclic changes of pelvic organs, and guide infertility treatment. In obstetrics, ultrasonic diagnosis is now widely used and has become an integral part of prenatal diagnosis. The clinical application of ultrasound covers the confirmation of pregnancy and multiple gestation, the estimation of gestational age, the localization of placenta and the monitoring of fetal well-being by analysing the blood flow index of umbilical artery, middle cerebral artery and renal artery. Hence, the department is a component part of the Prenatal Diagnosis Center in Zhejiang Province. It is in charge of the prenatal diagnosis of fetal anomalies, such as hydrocephalus, congenital heart diseases, anencephalia, and lip cleft. Our three-dimensional ultrasonic system, is able to evaluate anatomy and pathology with multiplane and surface-rendered images, which provides additional valuable clinical information. It also allows for new volume-rendering displays that show the depth, curvature, and surface images not available with conventional methods. For example, through the technique of surface- rendering, we can observe the interior of endometrial cavity more clearly, which is quite a match for hysteroscopy. The department has also developed many new techniques, including intraoperative ultrasonic monitoring, ultrasonic intervention (e.g. ultrasound guided puncture of pelvic mass), neonatal cardiac and transcranial ultrasonic diagnosis.
