【摘要】 目的:对比观察低剂量与常规剂量螺旋CT扫描对有症状患者胸部检查的差异,探讨对不同症状患者进行低剂量扫描的可行性。材料和方法:对有胸部症状的120例患者同时进行低剂量30mAs和常规剂量120mAs螺旋CT扫描,从发现病灶、病灶内部结构显示以及病灶定性等方面进行比较观察。对发现病变但不能定性者加做病灶局部靶扫描或高分辨扫描。结果:两种扫描方案对病灶的检出、病灶内部结构显示及病灶定性均无显著差异。薄层靶扫描或高分辨扫描可提高定性诊断率。结论:低剂量与常规剂量螺旋CT对有症状患者胸部检查具有相同价值,低剂量全肺扫描加病变部位靶扫描是胸部CT检查的最佳方案。更多还原

【Abstract】 Purpose:To observe the different of the low-dose spiral CT and regular dose CT in chest examination of patients and to evaluate the feasibility of scanning with low-dose spiral CT in the patients with chest symptoms.Materials and Methods:120 patients with chest symptoms were performed with the low-dose CT and the regular-dose CT scan.The finding of lesion,displaying of lesion structures and qualitative of lesion were compared.The local target CT scanning was performed in lesions of no qualitative.Results:There was no significant difference between two groups in finding lesion,displaying of lesion structures and qualitative of lesion.The local target CT scanning can improve the rate of qualitative dignoses.Conclusions:The low-dose spiral CT and regular dose CT have the same value in chest examination of patients.The low-dose spiral CT plus target scan is the best methods of examination in chest disease.更多还原
