To assess ultrasound (US) method informativeness in the recurrence detection and treatment monitoring of patients with cervical cancer metastases in the vagina via comparing the US and magnetic resonance imaging (MRI) data.
42 patients with recurrence of cervical cancer were examined by transvaginal US and MRI. Data on radiation diagnostics of cervical cancer metastasis in the vagina were compared with pathomorphological data. US and MRI data on the metastatic tumors size were compared.
The diagnostic efficiency of US and MRI for recurrence detection was determined. The sensitivity, specificity and accuracy of US were 92.8; 93.3 and 93.3%, respectively, and of MRI - 95.2; 96.6 and 95.8%, respectively. The informativeness of MRI was higher than US in cervical cancer recurrences detection, but the difference was not significant (p > 0.05). US can provide data as informative as MRI for estimation of metastases sizes in the vagina. The mean difference between MRI measurements and US measurements of the metastases volume was 0.79 mm (95% CI 0.62-0.95 cm).
US as a cheaper and simpler method could be an alternative for metastases detecting and treatment monitoring, especially if there are contraindications to MRI.
通过比较超声（US）和磁共振成像（MRI）数据，评估超声在宫颈癌阴道转移患者复发检测和治疗监测中的信息性。
对 42 例宫颈癌复发患者进行经阴道 US 和 MRI 检查。将阴道转移的放射诊断数据与病理形态数据进行比较。比较转移性肿瘤大小的 US 和 MRI 数据。
确定了 US 和 MRI 对复发检测的诊断效率。US 的灵敏度、特异性和准确性分别为 92.8%、93.3%和 93.3%，MRI 分别为 95.2%、96.6%和 95.8%。MRI 在宫颈癌复发检测中的信息性高于 US，但差异无统计学意义（p>0.05）。US 可提供与 MRI 一样有信息价值的评估阴道转移灶大小的数据。MRI 测量与 US 测量转移体积的平均差值为 0.79 毫米（95%CI 0.62-0.95 厘米）。
US 作为一种更便宜、更简单的方法，可以替代转移检测和治疗监测，特别是在 MRI 存在禁忌症的情况下。
