COMPARATIVE STUDY OF HYSTEROSCOPY AND 3D ULTRASOUND FOR DIAGNOSING UTERINE CAVITY ABNORMALITIES (Abstract) Objective: Hysteroscopy is the most accurate method for diagnosing intrauterine pathologies related to abnormal blee ding and infertility. The accuracy of three-dimensional (3D) ultrasonography and hysteroscopy were compared in identifying uterine cavity abnormalities. Material and methods...

because of superficial location and not being covered by boney structure, thyroid is the ideal organ for 2-dimensional gray scale ultrasonography. availability of relatively low cost equipment and ever increasing number of endocrinologists with expertise in thyroid ultrasound has made it an integral part of thyroid practice in the office of endocrinologists. in particular, the current recommend...

After introduction of high-frequency vaginal transducer, transvaginal two-dimensional ultrasound has established a field of sonoembryology and most of the major fetal abnormalities have been detectable in the first trimester. Three-dimensional ultrasound adds an objective and comprehensive information to two-dimensional sonographic findings.

Background: To investigate whether endometrial volume on the day of HCG (human chorionic gonadotropin) administration is a predictor of ART (assisted reproductive outcome) outcome Materials and Methods: Two hundred and seven patients in ART cycle were included in this prospective study; In order to evaluate endometrial volume and its relationship to ART outcome. Endometrial volume obtained from...

In a recent survey conducted in 30 centres with large experience in intracoronary ultrasound, three dimensional reconstruction of intracoronary ultrasound was ranked as the technical development with the lowest priority,' suggesting that it...

OBJECTIVE The purpose of this article was to review the published literature on 3-dimensional ultrasound (3DUS) and 4-dimensional ultrasound (4DUS) in obstetrics and determine whether 3DUS adds diagnostic information to what is currently provided by 2-dimensional ultrasound (2DUS) and, if so, in what areas. METHODS A PubMed search was conducted for articles reporting on the use of 3DUS or 4DU...

INTRODUCTION An imaging diagnosis after an iterative cesarean delivery is reviewed demonstrating a fine ultrasound-pathologic correlation. CASE PRESENTATION A 33-year-old woman (G3, P3) presented referring intense dysmenorrhea and intermenstrual spotting since her third cesarean delivery, 1 year before. A cesarean section dehiscence with utero-peritoneal fistula was diagnosed by transvaginal ...

Freehand three-dimensional (3D) ultrasound is a technique for acquiring ultrasonic data of a 3D volume with application in radiotherapy and surgery planning. As the clinician sweeps the ultrasound probe over the anatomy, the trajectory of the probe is recorded using an attached position sensor. However, the position sensor tracks the position of the sensor, rather than the ultrasound B-scan. It...

This paper describes a simulator of ultrasound-guided prostate biopsies for cancer diagnosis. When performing biopsy series, the clinician has to move the ultrasound probe and to mentally integrate the real-time bi-dimensional images into a three-dimensional (3D) representation of the anatomical environment. Such a 3D representation is necessary to sample regularly the prostate in order to maxi...

The objective of this article is to provide scientists, engineers and clinicians with an up-to–date overview on the current state of development in the area of three-dimensional ultrasound (3-DUS) and to serve as a reference for individuals who wish to learn more about 3-DUS imaging. The sections will review the state of the art with respect to 3-DUS imaging, methods of data acquisition, analys...
