Analysis of the spiral CT performance of tertiary silicosis by three-dimension thin-slice reconstruction / 中国基层医药

ABSTRACT

Objective To study the spiral CT performance of tertiary silicosis by three-dimension thin-slice reconstruction.Methods Sixty patients with tertiary silicosis were selected in the research.All of the patients were given thin slice scan,and the images of patients with tertiary silicosis were reconstructed by workstation,the spiral CT performance was analyzed.Results In all patients,the pulmonary large shadow mainly distributed in the upper middle lung field,accounted for 93.33％ (56/60).Big shadow internal signs for calcification,containing air bronchogram,empty.Big shadow around with signs of more complex,with 40 patients with adjacent pleural thickening phenomenon,accounted for 66.67％ (40/60).15 cases complicated with tuberculous,accounted for 25.00％ (15/60) of the total number of patients.3 cases with lung cancer,accounted for 5.00％ (3/60) of the total number of patients.Conclusion The spiral CT performance of tertiary silicosis by three-dimension thin-slice reconstruction is diversified,which included pulmonary large shadows with symmetric distribution,pleural thickening,bullae of lung in subintima,lymph gland swelling and calcification in mediastinum and hilus pulmonis.It can provide reference for the diagnosis of tertiary silicosis.
