Doppler Evaluation of the Ovary: Clinical Applications and Challenges

Ivica Žalud¹

Abstract: Abstract:Transvaginal sonography has been shown to be an accurate technique for discriminating between benign and malignant adnexal masses. Accurate preoperative differential diagnosis of adnexal masses is essential for optimizing patients' treatment. The advancement and wider availability of therapies of assisted conception have occurred to a large extent as a result of developments in ultrasonography. Transvaginal color Doppler has opened up exciting new possibilities for the better understanding of the phys… Show more

Objectives-The aim of this study was to assess the feasibility of the novel "superb microvascular imaging" (SMI) Doppler ultrasound technique to detect ovarian vascularity in healthy children and to compare it with the conventional Doppler ultrasound techniques.Methods-This prospective study included 140 girls, aged 3 to 18 years, for which an abdominal ultrasound study was requested in the pediatrics outpatient clinics for suspicion of nonovarian pathologies. Nineteen individuals were excluded from the study due to incomplete ultrasound scanning. For the remaining 121 cases, gray scale ultrasound evaluation was performed followed by color Doppler imaging, power Doppler imaging, advanced dynamic flow, color SMI, and monochrome SMI to detect the presence and degree of vascularity in the ovaries. Ultrasound scanning was performed for all participants by the same doctor by using curvilinear probe via the suprapubic approach, and the images were independently evaluated by 3 different observers. The images were assessed with regard to the degree of vascularity and the presence of artifacts.Results-A total of 146 ovaries (42 right, 54 left, and 25 bilateral) were examined by sonography. The mean interrater agreement regarding the detection of vascularity was moderate for the color Doppler imaging, power Doppler imaging, advanced dynamic flow, and monochrome SMI techniques (κ = 0.514-0.551) and substantial for the color SMI technique (κ = 0.636) (P < .001). The techniques were found to be statistically significant for detecting vascularity: monochrome SMI > color SMI > power Doppler imaging > color Doppler imaging > advanced dynamic flow (P < .001).Conclusion-SMI is a promising tool that can detect ovarian vascularity more effectively than the conventional Doppler ultrasound techniques.

Ultrasound frontiers are infinitive and some recent developments are discussed in this review. The author aims to provide the reader with the definition of 3D Doppler and its potential clinical applications. It also describes automatic fetal biometry and discusses clinical potentials of handheld ultrasound. The rapid development of these new sonographic techniques will continue to enlarge the scope of ultrasound applications in obstetrics and gynecology. 3D Doppler is a unique technique that enables assessment of vascular signals within the whole investigated area. Homodynamic changes included in the process of placentation are one of the most exciting topics in the investigation of early human development. The measurement errors produced by automated fetal biometry translate into very small errors regarding gestational age of the fetus. The automation of ultrasound measurements has great potentials in improving productivity and patient throughput, enhancing accuracy and consistency of measurements and reducing the risk of repetitive stress injuries users. Handheld ultrasound exam is reliable in making initial diagnosis required by the limited ultrasound exam in obstetrics and gynecology. Objectives Define 3D Doppler and its potential clinical applications Describe automatic fetal biometry Discuss clinical potentials of handheld ultrasound
