The present study evaluated the prognostic value of three-dimensional ultrasound for fetal hydronephrosis. Pregnant females with fetal hydronephrosis were enrolled and a novel three-dimensional ultrasound indicator, renal parenchymal volume/kidney volume, was introduced to predict the postnatal prognosis of fetal hydronephrosis in comparison with commonly used ultrasound indicators. All ultraso...

A 35 year-old woman referred to Royan Institute (Reproductive Biomedicine Research Center) for infertility treatment. She had an eleven-year history of primary infertility with a normal abdominal ultrasound. Hysterosalpingography (HSG) was obtained one month prior to referral in another center (Fig A). The HSG finding of an apparent unicorn uterus followed by a normal vaginal ultrasound led us ...

Conventional two-dimensional intracoronary ultrasound enables the extent, distribution, and therapy of atherosclerotic plaques to be studied as it provides a unique tomographic visualization of both the vascular lumen and wall'". The most important limitation of two-dimensional intracoronary ultrasound in pre/poststudies is the matching of the target sites for serial measurement. This problem i...

Prostate cancer is the most common cancer in adult men in North America. Preclinical studies of prostate cancer employ genetically engineered mouse models, because prostate cancer does not occur naturally in rodents. Widespread application of these models has been limited because autopsy was the only reliable method to evaluate treatment efficacy in longitudinal studies. This article reports th...

Evaluation of the fetal face with 3-dimensional ultrasound allows for evaluation of the fetal face using surface rendering, multiplanar and multislice displays. Three-dimensional ultrasound offers many benefits in evaluating the fetal face because it can be rotated into a standard symmetrical orientation and reviewed millimeters by millimeters by scrolling through the volumes. New rendering too...

New technology in ultrasound imaging is allowing women to view more visually precise images of their fetuses than ever before. Maternal-fetal bonding describes the attachment interaction that forms between a mother and her unborn child. Ultrasound diagnosis modalities including two-dimensional (2D), three-dimensional (3D) and four-dimensional (4D) may create differences in the amount of materna...

We deposited a lead zirconate titanete (PZT) polycrystalline film on a titanium substrate by the hydrothermal method and fabricated a transducer using the PZT film for use as an ultrasound probe. A 10MHz miniature one-dimensional-array medical ultrasound probe containing the PZT film was developed. After sputtering titanium on the surface of a hydroxyapatite substrate, the titanium film on the ...
