| 目的 观察最小表观弥散系数(ADC)值鉴别腮腺肿块的价值。方法 回顾性分析经手术病理证实的167例腮腺肿块患者(共265个肿块),测量并比较MRI所示肿块最小ADC值。结果 167例中,腮腺多形性腺瘤68例、73个肿块,最小ADC值(1.38±0.23)×10－3 mm2/s;腺淋巴瘤43例、54个肿块,最小ADC值(0.69±0.13)×10－3 mm2/s;恶性肿瘤31例、38个肿块,最小ADC值(1.08±0.20)×10－3 mm2/s;良性淋巴上皮病变7例、17个肿块,最小ADC值(0.64±0.10)×10－3 mm2/s;淋巴瘤5例、23个肿块,最小ADC值(0.56±0.12)×10－3 mm2/s;淋巴结炎性肉芽肿6例、28个肿块,最小ADC值(0.78±0.16)×10－3 mm2/s;淋巴结反应性增生7例、32个肿块,最小ADC值(0.75±0.13)×10－3 mm2/s。腮腺多形性腺瘤最小ADC值明显高于腺淋巴瘤、良性淋巴上皮病变及淋巴结病变(P均＜0.05);腮腺恶性肿瘤最小ADC值低于多形性腺瘤而高于其他良性肿块(P均＜0.05);腮腺淋巴结病变中,淋巴瘤最小ADC值低于良性淋巴结病变(P均＜0.05)。结论 最小ADC值对不同类型腮腺肿块具有鉴别诊断价值。 |

| Objective To explore the value of the minimum apparent diffusion coeffecient (ADC) value for differential diagnosis of parotid masses. Methods MRI data of 167 patients with 265 parotid masses confirmed by pathology were retrospectively analyzed, the minimum ADC value of masses were measured and compared. Results There were 68 cases and 73 masses of pleomorphic adenoma, with the minimum ADC value of (1.38±0.23)×10-3 mm2/s; 43 cases and 54 masses of adenolymphoma, with the minimum ADC value of (0.69±0.13)×10-3 mm2/s; 31 cases and 38 masses of malignant tumor, with the minimum ADC value of (1.08±0.20)×10-3 mm2/s; 7 patients and 17 masses of benign lymphoepithelial lesion, with the minimum ADC value of (0.64±0.10)×10-3 mm2/s; 5 patients and 23 masses of lymphoma, with the minimum ADC value of (0.56±0.12)×10-3 mm2/s; 6 patients and 28 masses of lymph node inflammatory granuloma, with the minimum ADC value of (0.78±0.16)×10-3 mm2/s; 7 patients and 32 masses of lymph node reactive hyperplasia, with the minimum ADC value of (0.75±0.13)×10-3 mm2/s. The minimum ADC value of pleomorphic adenoma was obviously higher than that of adenolymphoma, benign lymphoepithelial lesion and lymphadenopathy (all P<0.05); of malignant tumors was lower than that of pleomorphic adenoma (P<0.05 but higher than that of other benign lesions (all P<0.05). For parotid lymph node lesions, the minimum ADC value of lymphoma was lower than that of benign lesions (P<0.05). Conclusion The minimum ADC value was helpful for differential diagnosis of different kinds parotid masses. |
