Abstract:
Objective To explore the optimum dose of multislice spiral CT scan in the check of patients with chronic obstructive pulmonary disease(COPD).Methods 90 COPD patients were divided into the conventional dose group and low dose group,the quality of conventional-dose and low-dose scan was analyzed respectively.Results The two scanning methods enable images satisfactory requirements in the 90 cases,and low-dose CT radiation dose was significantly reduced(t=5.01,6.82,both P＜0.05).Conclusion For COPD patients using multi-slice spiral CT scan,low-dose scanning can not only meet the requirements of clinical diagnosis,but also significantly reduce the patient radiation dose.
