Is Diagnostic Ultrasound Harmful to the Fetus?

Ultrasound imaging of the early fetus : is it safe ? REVIEW

Diagnostic ultrasound has an excellent safety record in general and, in particular, in obstetrics. As a form of energy, ultrasound has effects in insonated tissues that are caused by two main mechanisms: thermal and nonthermal (also known as mechanical). Onscreen indicators of these potential bioeffects are the thermal and mechanical indices. Biological effects of ultrasound have been reported ...

Investigating the diagnostic value of tumor markers compared to ultrasound in the diagnosis of ovarian tumors

Aims: Ovarian cancer has the worst prognosis among female genital tract malignancies, but if detected in the early stages, it is one of the most treatable malignancies. The aim of this study was to investigate the diagnostic value of tumor markers compared to ultrasound in the diagnosis of ovarian tumors. Materials and methods: In this cross-sectional-analytical study, 210 women referred to ...

Ultrasound contributions to the management of the severely isoimmunized fetus.

Twenty-four out of 81 fetuses affected by anti-D isoimmunization underwent ultrasonic guided intrauterine transfusions (2.8 I. U. T.s per fetus). The absolute value and trend of delta OD 450 micron value was correlated with the severity of fetal condition as evaluated by ultrasonography following simple semiquantitative grading of ascites (mild, moderate, severe) and diagnosis of hydrops. The e...

Assessing the 'at-risk' fetus: Doppler ultrasound.

PURPOSE OF REVIEW Doppler ultrasound has become an indispensable tool in evaluating pregnancies at risk for conditions such as preeclampsia, intrauterine growth restriction, fetal anemia, and umbilical cord abnormalities. Use of umbilical artery, middle cerebral artery, and uterine artery Doppler has been the mainstay of assessment. RECENT FINDINGS Recent findings promote the use of ductus ve...
