چکیده

Recently, there have been several major technical advances in the sonographic diagnosis of ovarian cancer in its early stages. These include improved assessment of tumor morphology with transvaginal sonography (TVS), and detection and characterization of tumor neovascularity with transvaginal color Doppler sonography (TV-CDS) and contrast-enhanced transvaginal sonography (CE-TVS). This paper will discuss and illustrate these improvements and describe how they enhance detection of early-stage ovarian cancer. Our initial experience with parametric mapping of CE-TVS will also be mentioned.

Early Detection of Type II Ovarian Cancer with Labelled Microbubble Transvaginal Sonography

Ovarian cancer is the most lethal of all gynecological malignancies. However early detection can potentially improve the survival rate from 50 to 90%. Transvaginal sonography with the use of contrast-enhanced microbubbles has shown promise when used to detect malignant ovarian lesions in several studies [1-3]. This brief communication addresses the need and potential benefits of contrast enhanc...

Early Detection of Ovarian Cancer with Transvaginal Microbubble Sonography: Current and Potential Applications

Contrast Enhanced microbubble Transvaginal Sonography (CE-TVS) can distinguish benign and malignant ovarian tumors. Initial results from several medical centers around the world have indicated that there are unique enhancement patterns in ovarian neoplasms. Challenges to the implementation of CE-TVS remain since some aggressive ovarian tumors (type 2) that arise in the tubal epithelium and meta...

Early detection of ovarian cancer with contrast enhanced transvaginal sonography

The CE-TVS differs from standard transvaginal sonography in that its inclusion of intravenous injection of ultrasound contrast with a threeminute recording of time intensity curve and its offl ine analysis. Microbubbles are prepared by shaking for 45 seconds in a specially designed vial oscillator. After an antecubital intravenous line is placed, 3 μL/kg of Defi nity (Lantheus Medical Imaging, ...
