摘　　要：目的探究多层螺旋计算机断层扫描(MSCT)技术鉴别诊断腮腺肿瘤性质的应用价值。方法回顾性分析南阳市中心医院2022年1月至2023年8月收治的96例腮腺肿瘤患者的临床资料,所有患者均已完成MSCT检查,根据手术病理诊断结果,将患者分为良性组(n=62)与恶性组(n=34),比较两组MSCT征象,并以手术病理诊断结果为金标准,统计MSCT对恶性腮腺肿瘤的诊断效能。结果96例患者的MSCT检查结果显示,肿瘤位于浅叶占52.08%、位于深叶占35.42%,肿瘤形态规则占66.67%,肿瘤直径<3 cm占67.71%,肿瘤边缘清晰占70.83%,单发肿瘤占93.75%,肿瘤密度均匀的占63.54%,有囊变占46.88%,有淋巴结肿大占34.38%,轻度强化占37.50%、中等强化占33.33%、明显强化占29.17%。经病理检查,发现38例多形性腺瘤、21例腺淋巴瘤、3例基底细胞腺瘤、16例腺样囊性癌、18例黏液表皮样癌。两组肿瘤数目比较,差异无统计学意义(P>0.05);恶性组肿瘤位于深叶、形态不规则、直径≥3 cm、边缘不清晰、密度不均匀、发生囊变、发生淋巴结肿大、明显强化占比均高于良性组,差异均有统计学意义(P<0.05)。MSCT检查诊断恶性腮腺肿瘤的敏感度为82.35%(28/34),特异度为93.55%(58/62),准确率为89.58%(86/96),约登指数为0.759。结论MSCT鉴别诊断腮腺肿瘤性质的价值较高,临床可结合MSCT肿瘤位置、形态、大小、边缘、密度等特征的显现情况辅助鉴别良恶性肿瘤。Objective To explore the application value of multislice spiral computed tomography(MSCT)technology in the differential diagnosis of parotid gland tumor nature.Methods A retrospective analysis was conducted on the clinical data of 96 patients with parotid gland tumors admitted to Nanyang Central Hospital from January 2022 to August 2023.All patients underwent MSCT examination.Based on surgical pathological diagnosis results,patients were divided into a benign group(n=62)and a malignant group(n=34).The MSCT features of both groups were compared,and the pathological results were taken as the gold standard to evaluate the diagnostic efficacy of MSCT for malignant parotid tumors.Results The MSCT examination results from the 96 patients showed that tumors located in the superficial lobe accounted for 52.08%,while those in the deep lobe accounted for 35.42%.Tumor morphology was regular in 66.67%of cases,and 67.71%of tumors had a diameter of<3 cm.Clear tumor margins were observed in 70.83%of tumors,with solitary tumors accounting for 93.75%.Tumors with uniform density were observed in 63.54%,cystic changes in 46.88%,and lymph node enlargement in 34.38%.Degree of enhancement showed mild in 37.50%,moderate in 33.33%,and significant in 29.17%.Pathological examination revealed 38 cases of pleomorphic adenoma,21 cases of adenolymphoma,3 cases of basal cell adenoma,16 cases of adenoid cystic carcinoma,and 18 cases of mucoepidermoid carcinoma.There was no statistically significant difference in the number of tumors between the two groups(P>0.05).However,tumors in the malignant group were more likely to be located in the deep lobe,have irregular morphology,diameter≥3 cm,unclear margins,uneven density,cystic changes,lymph node enlargement,and significant enhancement compared to the benign group,with all differences reaching statistical significance(P<0.05).The sensitivity of MSCT in diagnosing malignant parotid tumors was 82.35%(28/34),specificity was 93.55%(58/62),accuracy was 89.58%(86/96),and the Youden index was 0.759.Conc
