Conventional sonographic evaluation of the cervix and vagina is compromised by inattention, poor subject contrast, and obscuring artifacts. We describe a technique involving distention of the vaginal canal and fornices with ultrasound gel, providing an acoustic window for improved definition of the cervix and vagina. This exam is usually performed in concert with transvaginal sonography, but a transabdominal or transperineal approach may be more useful in selected scenarios. A wide variety of formerly sonographically inconspicuous conditions are demonstrable with this technique, many of which were undetected or inadequately characterized on the physical exam. Cervical polyps were the most commonly seen abnormality.
对宫颈和阴道进行传统超声评估时，会因注意力不集中、受检部位对比度差以及伪像干扰而受到影响。我们描述了一种技术，即使用超声凝胶扩张阴道管和穹窿，从而提供一个声学窗口，以更好地显示宫颈和阴道。这项检查通常与经阴道超声检查同时进行，但在某些特定情况下，经腹或经会阴途径可能更有用。使用这种技术可以显示出许多以前超声检查难以发现的情况，其中许多在体格检查中未被发现或特征描述不充分。宫颈息肉是最常见的异常情况。
