摘要
目的探索腮腺占位性病变临床诊断中应用螺旋CT双期增强扫描的效果与价值。方法选取2019年4月—2022年6月本院收治的60例腮腺占位性病变患者进行研究。术前对所有患者进行256层螺旋CT平扫和双期增强扫描诊断,将患者诊断的病理结果作为金标准,分析螺旋CT双期增强扫描诊断效能,对比良性组与恶性组影像学资料,观察并分析腮腺占位性病变特点。结果60例腮腺占位性病变患者术后病理检查,确诊12例恶性肿瘤(20%)和48例良性肿瘤(80%);经螺旋CT双期增强扫描诊断60例腮腺占位性病变患者,检查确诊恶性病变9例(15%),良性病变51例(85%),特异度为95.83%(46/48),敏感度为58.33%(7/12),准确度为88.33%(53/60),一致性为0.762>0.74,具备良好一致性;良性和恶性组患者影像学资料对比,病灶形态、边界存有明显差异,具备统计学意义(P<0.05);腺淋巴瘤平扫CT值最高,平扫CT最低为多形性腺瘤,与其他各组比较差异明显,有统计学意义(P<0.05);在螺旋CT双期增强扫明中,腺淋巴瘤动脉期强化程度最高,差异有统计学意义(P<0.05);门脉期各病理类型腮腺肿瘤强化程度有差异,具备统计学意义(P<0.05)。螺旋CT双期增强扫描能够准确诊断腮腺占位性病变性质,为疾病诊断提供依据。结论CT技术采取双期增强扫描方式在诊断腮腺占位性病变中,准确性较高,能准确诊断病灶边界、形态,具有临床诊断与应用的价值,值得大力推广。
Objective To explore effect and value of dual phase enhanced spiral CT in clinical diagnosis of parotid gland occupying lesions.Methods The paper chose 60 patients with parotid gland space occupying lesions in our hospital from April 2019 to June 2022.Before surgery,patients were diagnosed with 256 slice spiral CT plain scan and biphasic enhanced scan.Pathological results and diagnostic effect of patients were analyzed with"gold standard"of pathological diagnosis results.Imaging data of benign and malignant groups were compared,characteristics of parotid gland occupying lesions were observed and analyzed.Results Postoperative pathological examination confirmed 27 malignant tumors(45%)and 33 benign tumors(55%)respectively among 60 cases with parotid gland occupying lesions.Dual phase enhanced spiral CT scanning confirmed 21 cases(35%)malignant lesions and 39 cases(65%)benign lesions among 60 cases with parotid gland space occupying lesions,with specificity of 90.24%(37/41),sensitivity of 89.47%(17/19),accuracy of 90.00%(54/60),and consistency of 0.762.Imaging data of benign and malignant groups showed significant difference in lesion morphology and boundaries,with statistical significance(P<0.05).Adenoma had the highest CT value on plain scan,and pleomorphic adenoma had the lowest CT value on plain scan,with significant statistical difference compared with other groups(P<0.05).During dual phase enhanced spiral CT scan,arterial phase enhancement of adenolymphoma was the highest,difference was statistically significant(P<0.05).Enhancement degree of parotid gland tumors varied among different pathological types during portal phase,with statistical significance(P<0.05).Observation of parotid gland occupying lesions revealed dual phase enhanced spiral CT scanning could accurately diagnose nature of parotid gland occupying lesions,provide basis for disease diagnosis.Conclusion CT technology with dual phase enhanced scanning can achieve high accuracy in diagnosing parotid gland occupying lesions,diagnose lesion boundarie
