| 目的 探讨超声弹性成像(UE)技术在腮腺良恶性结节鉴别诊断中的价值。方法 以85例腮腺结节患者(共96个腮腺结节)为研究对象,术前行常规超声和UE检查,回顾性分析超声特征、弹性评分及病理结果。结果 96个腮腺结节中,经术后病理诊断良性53个,恶性43个。弹性评分>3分、诊断为恶性者47个,弹性评分≤3分、诊断为良性49者。弹性评分≤3分者中,良性病灶所占比例(46/53,86.79%)高于恶性病灶(3/43,6.98%),差异有统计学意义(χ2=60.52,P<0.05),误诊率差异无统计学意义 。采用UE诊断腮腺结节良恶性的敏感度、特异度、准确率、阳性预测值及阴性预测值均高于常规超声(P均<0.05)。结论 UE在一定程度上可区分良恶性腮腺结节。在评估腮腺结节性质时,需结合常规超声、病史及临床表现综合评估。 |

| Objective To explore the value of ultrasonic elastography (UE) in differential diagnosis of benign and malignant parotid tumors. Methods A total of 85 patients with parotid tumors (96 nodules) underwent conventional ultrasound and UE before operation, then the ultrasound features, elasticity score and pathological results were compared. Results Of the 96 parotid tumors, there were 53 benign and 43 malignant tumors. There were 47 malignant tumors with UE score >3 and 49 benign ones with UE score ≤3 by UE. The rate of UE score ≤3 in benign tumors (46/53, 86.79%) was higher than that in malignant tumors (3/43, 6.98%, χ2=60.52, P<0.05), but there was no significance in misdiagnosis rate (13.21% [7/53] vs6.98% [3/43], χ2=0.988, P>0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of UE in diagnosis of parotid tumors were higher than those of conventional ultrasound (all P<0.05). Conclusion UE is useful for differential diagnosis of parotid tumors. It is necessary to consult with the conventional ultrasound, medical history and the clinical features. |
