Abstract：Objective The diagnostic value is evaluated by Low-dose and ultra-high-resolution CT(UHRCT)used to screen ground-glass nodules.Methods 97 patients with ground-glass nodules were examined with low-dose and UHRCT.And we evaluated the malignancy,accuracy,specificity and sensitivity of pulmonary ground-glass nodules,and evaluated the character-istics of pulmonary ground-glass nodules.Results The malignant and benign cases with low-dose CT were detected of 47 cases and 50 cases,with UHRCT on 43 cases and 54 cases,and 42 cases and 55 cases were detected by UHRCT.The accuracy,specificity and sensitivity of the combined method and UHRCT were 94.85%,95.12%,94.64%and 88.66%,92.68%,91.07%,which were higher than those of 77.32%,80.49%,75.00%in the low dose CT group.The accuracy of the combined method was higher than that of UHRCT.There was significant difference between UHRCT and low-dose CT(P<0.05).Conclusion Low dose combined with UHRCT and combined detection of pulmonary ground glass nodules have better clinical efficacy.
