Abstract：
UNASSIGNED: A simple and efficient tool for evaluating ovarian tumors in general hospitals where radiologists without experience in gynecological ultrasound is necessary. This study aims to evaluate the diagnostic performance of IOTA simple rules in initial classification of ovarian tumors by non-experienced examiners who have received simple training.
UNASSIGNED: A prospective single-center study was conducted at Hanoi Obstetrics and Gynecology Hospital. Three resident gynecologists trained themselves for two weeks and then received hands-on practice under the supervision of experts for another two weeks. The examiners performed ultrasound on 424 eligible women scheduled for surgery for ovarian tumors and classified the tumors based on IOTA simple rules. The postoperative pathology of ovarian tumors was used as the gold standard.
UNASSIGNED: 90.8 % (385/424) of the tumors were benign. Simple rules were applicable in 399/424 (94.1 %) tumors, with a sensitivity of 84.8 % (95 % CI, 70.2-94.3), specificity of 98.9 % (95 % CI, 97.5-99.7), positive predictive value of 87.5 % (95 % CI, 73.3-95.9), and negative predictive value of 98.6 % (95 % CI, 97.1-99.5). The sensitivity of IOTA simple rules was higher in postmenopausal women (91.7 % vs. 81.0 %), while the specificity was higher in premenopausal women (99.4 % vs. 95.8 %). Accuracy was 100 % in all ten pregnant women were assessed using these rules.
UNASSIGNED: In conclusion, in the hands of non-expert examiners who were trained thoroughly, IOTA simple rules are a simple and efficient tool for clinical practice in centers where expert radiologists in gynecology are not always available. The training program is simple and could be applied widely in other clinical centers. Further studies are necessary to evaluate the effectiveness of the IOTA simple rules in assessing ovarian tumors among pregnant women.

摘要：
■一种简单有效的工具，用于在没有妇科超声经验的放射科医生的综合医院中评估卵巢肿瘤。这项研究旨在评估IOTA简单规则在接受简单培训的无经验检查者对卵巢肿瘤的初始分类中的诊断性能。
■在河内妇产科医院进行了一项前瞻性单中心研究。三名驻地妇科医生对自己进行了为期两周的培训，然后在专家的监督下进行了为期两周的实践。检查人员对424名计划接受卵巢肿瘤手术的合格女性进行了超声检查，并根据IOTA简单规则对肿瘤进行了分类。以卵巢肿瘤的术后病理作为金标准。
■90.8%(385/424)的肿瘤是良性的。简单规则适用于399/424（94.1%）肿瘤，灵敏度为84.8%(95%CI，70.2-94.3)，特异性98.9%（95%CI，97.5-99.7），阳性预测值为87.5%（95%CI，73.3-95.9），阴性预测值为98.6%（95%CI，97.1-99.5）。绝经后妇女IOTA简单规则的敏感性更高(91.7%vs.81.0%），而绝经前女性的特异性更高(99.4%vs.95.8%）。使用这些规则评估的所有10名孕妇的准确性为100％。
■总而言之，在经过全面培训的非专家审查员手中，IOTA简单规则是在妇科放射科专家并不总是可用的中心进行临床实践的简单有效工具。该培训计划简单，可在其他临床中心广泛应用。需要进一步的研究来评估IOTA简单规则在评估孕妇卵巢肿瘤中的有效性。
