Sub-optimal placement of both intracavitary devices and interstitial needles is a relatively common occurrence in cervical brachytherapy, which may reduce the accuracy of dose distribution and contribute to adverse toxicities. To mitigate complications, improve target dose coverage, and verify proper device placement, implants may be placed under real-time image guidance. Traditionally, transrectal ultrasound has been used for needle guidance. However, we have utilized transabdominal ultrasound (TA-US) in our brachytherapy center. The purpose of this pictorial essay was to provide a pictorial description of TA-US technique, present a retrospective review of our preliminary outcomes adopting TA-US into routine practice, and to discuss the advantages of real-time ultrasound image guidance for placement of intrauterine tandem and interstitial needles.
腔内装置和组织间插植针放置欠佳在宫颈癌近距离治疗中较为常见，这可能会降低剂量分布的准确性并导致不良毒性反应。为了减轻并发症、改善靶区剂量覆盖并验证装置放置正确，植入操作可在实时图像引导下进行。传统上，经直肠超声用于针引导。然而，我们在近距离治疗中心使用的是经腹超声（TA-US）。本文的目的是对TA-US技术进行图示描述，回顾我们将TA-US应用于常规实践的初步结果，并讨论实时超声图像引导在子宫内施源器和组织间插植针放置中的优势。
