Abstract:
OBJECTIVEThe purpose of this study is to decide how to select the best scan parameters in low dose computed tomography screening.
METHODSUse 140 kV, 20 mA, 30 mA, 40 mA, 50 mA, 200 mA scanning to get the images' intensity resolution and high contrast resolution, and select the images which can meet the national standard, Then get the scan parameters when the mA is lowest. Scan 60 patients using the standard CT and low dose CT separately to get the scan images. After that, two senior radiology doctors were invited to evaluate the images' quality.
CONCLUSION140 kV, 30 mA is the best scan parameters for lung cancer.
