The efficacy of ultrasonography was evaluated in radiotherapy for 32 patients with 82 metastatic bone tumor regions. Except for vertebral columns, ultrasonography was useful to detect metastatic bone tumors. Ultrasonography was applied to the radiotherapy planning in 21 regions, and was useful for the evaluation of radiotherapy effects in 22 regions. An appearance of "anechoic band" was useful for estimating tumor localization, and may be useful for the determination of the adequate dosage for palliative irradiation. Ultrasonography enable accurate localization of tumors such as sternal or costal metastases that are difficult by fluoroscopy. This means should be executed by radiotherapists.
对32例有82个转移性骨肿瘤区域的患者进行超声检查在放射治疗中的疗效评估。除脊柱外，超声检查对检测转移性骨肿瘤有用。超声检查应用于21个区域的放射治疗计划，对22个区域的放射治疗效果评估有用。“无回声带”的出现有助于估计肿瘤定位，可能有助于确定姑息性放疗的合适剂量。超声检查能够对透视难以检测的胸骨或肋骨转移等肿瘤进行精确定位。这一方法应由放射治疗师实施。
