Abstract：Objective:Analyzing the performance of focal ground glass that under MDCT thin thickness reconstruction, and obtaining CT features of focal ground glass opacity from early stage lung cancer. Method:53 clinically or pathologically confirmed fGGO were collected and analyzed clinical informations and imaging features including lesion location and size, shape, margin, interface, internal density, pleural indentation, vacuole, air bronchus-charging sign and blood vessel clustering. Statistical analyze the differences between the benign and malignant.Results: There were statistical differences between benign and malignant fGGOs in terms of margin (P=0.001), interface (P=0.000)and blood vessel clustering (P=0.009) as well as gender (P=0.120), age (P=0.437), location (P=0.565) size (benign 1.55±0.67) cm, malignant (1.54±0.85) cm,(P=0.978), shape, vacuole (P=0.100), air bronchus-charging sign (P=0.211) and pleural indentation (P=0.243)doesn't significantly found in malignant fGGOs. Conclusion:Margin, interface and blood vessel clustering can make contribute to early lung cancer diagnosis and differentiation of benign and malignant fGGOs.
