Diagnostic value of 16-slice spiral computed tomography in detecting lesions in parenchymatous organs of the digestive system

目的研究16层螺旋计算机断层扫描(computed tomography,CT)在消化系统实质器官检查技术及其在不同病变诊断中应用价值.方法回顾性分析2012-01/2017-01在厦门大学附属第一医院接受治疗的肝脏肿瘤和肿瘤的病变患者105例,胰腺病变患者84例,脾脏病变患者111例;使用16层螺旋CT对肝脏和脾脏病变患者进行平扫加增强,对胰腺患者进行灌注扫描,分析患者的病变特征.结果C T上肝脏和脾脏病变的表征是多发或单发的低密度的病灶,边界可模糊也可清晰,增强后可不强化也可强化;胰腺癌患者Q_b、V_b低于正常者,t_(mt)、K_(ps)高于正常者,两组间t_(mt)、K_(ps)、Q_b、V_b对比差异均有统计学意义(P<0.05);胰腺炎患者的Q_b、V_b、K_(ps)与正常者对比差异有统计学意义(P<0.05),tm t与正常者对比差异无统计学意义(P>0.05);胰腺癌患者的Q_b、V_b、tm t和胰腺炎患者对比差异均有统计学意义(P<0.05).结论16层螺旋C T对肝脏病变、胰腺病变和脾脏病变患者有较高的诊断价值,值得在临床推广.

AIM To assess the diagnostic value of 16-slice spiral computed tomography （CT） in detecting lesions in parenchymal organs of the digestive system.METHODS One hundred and five patients with liver lesions, 111 patients with pancreatic disease, and 84 patients with splenic lesions treated at our hospital from January 2012 to January 2017 were enrolled in this study. All patients underwent 16-slice spiral CT examinations. Patients with liver or splenic lesions underwent both plain and contrast-enhanced CT examinations, and patients with pancreatic disease underwent perfusion scans. The CT features of different lesions were analyzed.Liver and spleen lesions were multiple or single and showed low density on plain CT, and the boundaries could be blurred or clear. On contrast-enhanced CT, the lesions may be enhanced or not. Qb and VB in pancreatic cancer patients were significantly lower than those in normal controls （P 〈 0.05）, while trot and Kps were significantly higher than those in normal controls （P 〈 0.05）. Qb, Vb, and Kp differed significantly between patients with pancreatitis and normal controls （P 〈 0.05）, while tmt showed no significant difference. Qb, Vb, and trot differed significantly between patients with pancreatic cancer and those with pancreatitis （P 〈 0.05）.CONCLUSION 16-slice spiral CT has high diagnostic value for hepatic, pancreatic, and splenic lesions.
