Ultrasound Killeen TX
Ultrasounds are used during pregnancy to visualize and monitor the developing fetus. By doing ultrasounds doctors can create images of a fetus, check its position, check for physical abnormalities and determine the sex, among other things.
Echogenic intracardiac focus (EIF) has been identified as a common ultrasound finding in association with fetal aneuploidy. Little is known about the association of this soft marker aneuploidy in various ethnic groups. Although it is commonly thought Asians in general have a higher incidence of EIF, it is unknown whether this also applies to Japanese as a subpopulation. The purpose of this study is to determine the antenatal incidence and postnatal significance of EIF observed during sonography in Japanese patients.
We present a case of monochorionic triamniotic triplet pregnancy diagnosed at 15 weeks of gestation with one fetus having developed a multicystic lung lesion, suggestive of congenital cystic adenomatoid malformation (CCAM). At 24 weeks, the largest cyst measured 10 mm in diameter. We managed the pregnancy conservatively and delivered three live male fetuses with birth weights 1560 g, 1580 g and 1590 g at 35 weeks of gestation.
Two studies have been experienced on the experts' knowledge system since 1980 1), 2) and neural network (NNW) system recently 3) , because it was suggested that more easy and widely applicable computerized fetal monitoring technique should be created from the improved outcome obtained by the general use of external monitoring 4) . Although the experts system was successful, we further tried its comparison to more objective NNW one in this study.
Prediction of Complete Uterine Rupture by Sonographic Evaluation of the Lower Uterine Segment Killeen TX
prospective cohort study of women with prior cesarean was conducted. LUS thickness was measured between 35 and 38 weeks of gestation. The thinnest measurement was conserved as the dependent variable. Receiver operating curve (ROC) analyses determined the optimal cut-off value for sensitivity and specificity. Potential confounding factors were considered by regression analyses.
A synechia is a term meaning an "adhesion", or a fibrous scar. Uterine synechiae have also been referred to as "amniotic sheets" or "amniotic folds". Many patients with sonographically demonstrable uterine synechia have clinical history of uterine instrumentation (voluntary termination, D&C) or uterine infections to explain scar formation.
Breast ultrasound is a diagnostic rather than a screening procedure; it is targeted to a specific clinical or focal mammographic finding in the vast majority of patients. Breast ultrasound should be performed on palpable lumps when the mammogram in the area of the lump is negative or nonspecific. Although, there are now a few studies on whole breast screening ultrasound.
Three-dimensional ultrasound (3D US) is a new imaging modality, which is being introduced into clinical practice. Although this technique will not probably replace two-dimensional ultrasound, it is being increasingly used. It has been reported that 3D US is a very high reproducible technique.
With the ExAblate (MR guided Focused Ultrasound Surgery) procedure the test must be done in a Closed MRI with and without contrast. The patient is not allowed to eat or drink for six (6) hours before the test. Patient positioning is feet first, prone, and an empty bladder. The scan should cover the entirety of the uterus; clearly showing the fibroid and uterus boundaries, and images should clearly show sacral bones, pubic bones, and bowel loops.
In HIFU therapy, Ultrasound beams are focused on diseased tissue, and due to the significant energy deposition at the focus, temperature within the tissue rises to more than 65°C, destroying the diseased tissue. This technology can achieve precise "ablation" of diseased tissue, therefore being called HIFU surgery.
