目的研究螺旋CT在胸腺疾病诊断中的应用与可行性。方法 45例经手术及病理证实的胸腺病变患者,按照病理结果分为A组(良性及低危组)、B组(高危组)以及C组(癌及癌类组),各15例。对比三组病灶的形态、边缘、密度、周围侵犯情况以及最长径。结果三组患者肿瘤最长径比较差异无统计学意义(P>0.05);A组患者肿瘤形态规则、边缘光滑、密度均匀和周围无侵犯所占比例均高于B组、C组,差异具有统计学意义(P<0.05);B、C组患者肿瘤形态规则、周围无侵犯所占比例比较差异无统计学意义(P>0.05);B组患者肿瘤边缘光滑、密度均匀所占比例分别为53.33%、53.33%,均高于C组的6.67%、13.33%,差异具有统计学意义(P<0.05)。结论螺旋CT在诊断胸腺疾病方面具有较高的临床价值和可行性。
Objective To study the feasibility and application of spiral CT in the diagnosis of thymus diseases. Methods 45 cases of thymus lesions confirmed by operation and pathology were divided into group A (benign and low risk group), group B (high risk group) and group C (cancer and carcinoid group), 15 cases in each group. The morphology, margins, density, surrounding violations and the longest diameter of the three groups were compared. Results There was no significant difference in the longest tumor diameter between the three groups (P> 0.05). The proportion of tumor in group A was higher than those in group B and C (P <0.05). There was no significant difference in the proportion of non-infiltrating tumor between groups B and C (P> 0.05). The proportions of tumor with smooth and uniform density in group B were 53.33% and 53.33% respectively, all higher than those in group C (6.67% and 13.33%, respectively). The difference was statistically significant (P <0.05). Conclusion Spiral CT in the diagnosis of thymus disease has a high clinical value and feasibility.
