To explore the sensitivity and specificity of ultrasonographic (US) elastography using carotid arterial pulsation as compression source for differential diagnosis thyroid nodules.This HIPAA-compliant study was approved by ethics committee institution, all patients provided written informed consent. Fifty-eight (13 men 45 women [mean age, 51 years; range, 20-76 years]) were enrolled. A short US examination with artery used performed before fine-needle aspiration. Baseband data downloaded...
A recurring source of contention between clinicians and radiologists continues to be examination appropriateness when imaging pregnant patients. With the multitude references on potential radiation risks fetus, tend cautious hesitant about exposing fetus radiation. This tendency is often interpreted by referring physicians as intrusion into delay in care their The risk burden exposure has carefully weighed against benefits obtaining a critical diagnosis quickly using single tailored study....
The purpose of this study was to evaluate the feasibility ultrasound thyroid elastography using carotid artery pulsation as compression source and its potential for differential diagnosis nodules.Baseband sonographic data were acquired 16 nodules from 12 patients. natural used source, strain estimated offline. For quantitative assessment tissue stiffness, a new metric called stiffness index (TSI) computed ratio near (high-strain region) that stiff region (low-strain inside nodule....
To assess whether a standardization exercise prior to commencing fetal growth study involving multiple sonographers can reduce interobserver variation.In preparation for an international assessing growth, nine experienced from eight countries participated in consisting of theoretical and practical sessions. Each performed set seven standard measurements on pregnant volunteers at 20-37 weeks' gestation, these were repeated by the lead sonographer; all taken blinded fashion. After this had...
Successful management of fetal conditions in which airway obstruction is anticipated now possible because advances prenatal imaging and the development innovative techniques to secure before complete separation fetus from maternal circulation. Fetal ultrasonography magnetic resonance are complementary modalities assessment fetuses with potential obstruction. The ex utero intrapartum therapy (EXIT) procedure used delivery fetus. However, successful treatment who may need prolonged placental...
Purpose To investigate performance in detectability of small (≤1 cm) low-contrast hypoattenuating focal lesions by using filtered back projection (FBP) and iterative reconstruction (IR) algorithms from two major CT vendors across a range 11 radiation exposures. Materials Methods A phantom consisting 21 objects (seven sizes between 2.4 10.0 mm, three contrast levels) embedded into liver-equivalent background was scanned at exposures (volume dose index range, 0.5–18.0 mGy; size-specific...
Preterm birth is a major global health challenge, the leading cause of death in children under 5 years age, and key measure population's general nutritional status. Current clinical methods estimating fetal gestational age are often inaccurate. For example, between 20 30 weeks gestation, width 95% prediction interval around actual estimated to be 18-36 days, even when best ultrasound estimates used. The aims this study improve provide personalised predictions future growth.Using...
Background: We investigated if thyroid nodule taller-than-wide (TTW) feature and sphericity metrics are helpful in separating benign neoplastic nodules (follicular oncocytic adenomas) from follicular carcinomas (FTC) (OCA). Methods: This is a retrospective study of TTW sonographic as reported by radiologists at two academic health systems. Surgical pathology reports for malignant neoplasms, non-neoplastic (hyperplastic adenomatoid), classic papillary cancers (PTC) were extracted enterprise...
