ABSTRACT Background The assessment of the endometrial receptivity at the time of human chorionic gonadotrophin (hCG) is one of the key factors for success of all ART procedures. Aim To assess, if 3D and 3D power Doppler assessment of endometrial receptivity before giving hCG, helps improving pregnancy rates in superovulation with IUI cycles. Settings and Design A prospective randomized study of 2500 cycles of IUI was done over a period of twelve months for pre-hCG endometrial assessment. Method Endometrial assessment was done on Voluson 730 Expert, (Wipro GE) using transvaginal multifrequency volume probe 5 to 9 MHz. When follicles and endometrium were considered mature by 2D US and color Doppler, 3D and 3D power Doppler assessment of the endometrium was done before giving hCG. These values were evaluated for conception and nonconception groups. Results Conception rates were higher, when endometrial volume was between 3 and 7 cc. In our study, we have found endometrial FI > 20 and endometrial VFI > 40 as most optimum. Conclusions 3D ultrasound is accurate for volume assessment of endometrium. 3D and 3D PD, when used with 2D US and color Doppler for pre-hCG endometrial assessment, it would definitely improve implantation rates in IUI cycles.

Case Based

ABSTRACT Uterine bleeding is a symptom seen by gynecologists in approximately 70% of their visits with women of peri and postmenopausal age. A common symptom, postmenopausal bleeding sometimes can be indicative of malignant pathology. While traditional diagnosis took place via endometrial biopsy, diagnosis is trending toward the use of ultrasound. Benefits of ultrasound include its noninvasive nature, decreased cost, and increased accuracy in diagnosis of postmenopausal bleeding. We present a case-based approach to the usage of various ultrasonography techniques including 2D and color Doppler ultrasound, saline infusion sonography (SIS), 3D and 3D power Doppler ultrasound, as complements to traditional diagnosis of endometrial biopsy. In each of the cases, ultrasonography reveals the diagnosis of postmenopausal pathologies, including atrophic endometrium, endometrial polyps, endometrial hyperplasia, and the malignant pathology, such as endometrial carcinoma, uterine leiomyosarcoma and cervical carcinoma. By the end of our case-based discussion, learners are encouraged to test their knowledge in self-assessment quiz. How to cite this article Appleton K, Plavsic SK.

Ultrasound Features

ABSTRACT Evaluation of the complete cycle instead of only pre hCG scan is an essential for follicular monitoring. Using color Doppler in this assessment is mandatory because it allows to assess the functional status of follicle and endometrium. 3D ultrasound is useful for volume measurements, and 3D PD for assessment of global vascularity. Baseline scan is done to predict the ovarian reserve and response and decide the stimulation protocols for ARTs. Uterus is assessed for receptivity. But baseline scan also diagnoses PCOS. This is by counting antral follicles, stromal flows and stromal and ovarian volume. Ultrasound features of ovary on baseline scan can also be correlated closely with the baseline hormonal status of ovaries—LH, FSH and Androgen. Ultrasound is a key tool to decide follicular maturity and endometrial receptivity and to decide the time of hCG and time of IUI. Doppler plays a major role in correct decision making and 3D and 3D power Doppler add to the details and also improves the success rates of different ARTs. Luteal phase also can be better explained by the use of Doppler. Ultrasound to hormonal correlation in both preovulatory and luteal phase helps plan the ART for positivity.

ABSTRACT Advanced ultrasound technology has been a valuable tool in the assessment of placental anatomy and physiology. Conventional two-dimensional (2D) sonography reveals placental morphological characteristics, 2D color Doppler can assess blood flow in the placenta, 2D power Doppler can evaluate placental vascular trees, and three-dimensional (3D) ultrasound gives more detailed information on the surface anatomy. Recent advances, such as 3D power Doppler with virtual organ computer aided-analysis (VOCAL) and histogram analysis can measure the placental volume, and assess uteroplacental and fetoplacental perfusions. In particular, ‘placental vascular sonobiopsy’ can specifically evaluate the second- and thirdtrimester placental blood flow and vascularity by obtaining several spherical samples from the placenta that will represent the entire placenta. This article presents normal placental development and pathological findings of the placenta using 3D power Doppler ultrasound, and discusses 3D power Doppler assessments of placental perfusion in high-risk pregnancies, such as fetal growth restriction, pregnancy-induced hypertension and preeclampsia, and, from this basis, re-establishes the importance of 3D power Doppler ultrasound as a screening, diagnostic, and surveillance tool in normal and abnormal pregnancies.

Follicular Vascularity

ABSTRACT Assessment of the follicular maturity and endometrial receptivity and the time of hCG is one of the key factors for success of all ART procedures. Maturation of the follicle and the endometrium, ovulation and leutinization is a process of multiple biochemical, morphological and vascular changes. The vascular changes are reflection of the biochemical changes and can be studied by color Doppler. 3D ultrasound gives a better assessment of the follicular and endometrial size, that is the anatomical maturity, than 2D ultrasound and 3D power Doppler gives not only qualitative but also quantitative idea of global vascularity, that is the reflection of functional/physiological maturity. Follicular vascularity distribution and flow indices can be better parameters of follicular quality and can be more reliable parameters to decide the time of hCG and IUI. Endometrial assessment can be more meaningful if its morphology is studied more in detail along with abundance of its vascularity as well as flow indices. Thus, deciding correct time of hCG can improve conception rates in ART cycles. How to cite this article Panchal S, Nagori CB. Follicular Monitoring.

Abstract The advances in ultrasound technology has changed the management of infertility. With the advent of color Doppler, pulse Doppler, 3D US and then 3D power Doppler the previously unexplained causes of failure of fertilization and implantation can now be explained. 3D and 3D power Doppler can now be used for the assessment of the maturity of the follicle and receptivity of the endometrium and can give better idea about the functional maturity of the follicle and the endometrium, to decide the timing of hCG administration for all assisted reproductive techniques for better pregnancy rates. The accuracy of diagnosis and monitoring of infertility treatments such as ovulation induction has greatly increased because of the availability of sophisticated ultrasound technology and equipment.1

ABSTRACT This review aims to provide the reader with an update on the present and potential clinical applications in Doppler ultrasound in perinatal medicine. Umbilical artery Doppler plays an important role in the management of intrauterine growth restriction (IUGR) and pre-eclampsia and aids in twin-to-twin transfusion syndrome management while notching in the waveform is a predictor of umbilical cord abnormalities. Middle cerebral artery Doppler reliably detects fetal anemia and may be useful in the assessment of IUGR as well. Abnormal uterine artery Doppler may play a role in predicting growth restriction, hypertensive disorders of pregnancy and preterm delivery. Abnormal ductus venosus waveforms can also be used to predict adverse fetal outcome and may allow for better timing of delivery while umbilical venous pulsations may be a sensitive marker for fetal heart failure in hydropic pregnancies. 3D power Doppler allows better small vessel visualization that is not affected by angle of insonation and has been used to diagnose placental and cord abnormalities. Significant improvements have recently occurred, improving the visualization and evaluation of placental vascularity, resulting from enhancements in delineation of tissue detail through electronic compounding and harmonics as well as enhancements in signal processing of frequency- and/or amplitude-based color Doppler ultrasound. Spatial representation of vascularity can be improved by utilizing 3D processing. Greater sensitivity of 3D Doppler ultrasound to macro- and microvascular flow has provided improved anatomic and physiologic assessment throughout pregnancy. The rapid development of these new ultrasound techniques will continue to enlarge the scope of clinical applications in placental studies. As clinical experience with these new technologies increases and as the technology improves further, it is reasonable to expect that 3D Doppler and 4D ultrasound will be complementary addition to well-established 2D Doppler ultrasound imaging.
