Compare Research On Imaging Examination Methods And Charather For Children's Small Airway's Disease

Objective: To approach the best imaging examination methods for children's small airways disease and the imaging character of small airways disease based on the control imaging study of normal, small airways disease, pneumono-consolidation (including chest X-ray, spiral computed tomography, High-resolution computed tomography).Methods: (1) 24 normal children were chosen as the control group and the studies of the quantity of the pulmonary small vascular and the condition of pneumono-oblique fissure were carried on.(according to study same level and same area of the imaging of spiral computed tomography and High-resolution computed tomography); (2) 36 abnormal children with the small airways disease were compared with tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern, bronchial mucoid impaction, bronchial dilatation ( according to the chest X-ray, spiral computed tomography and High-resolution computed tomography) (3) 30 abnormal children with pneumono-consolidation≥5 centimeter were compared with the above conditions. Results: (1) In the normal group, the quantity of the pulmonary small vascular and the condition of pneumono-oblique fissure is more in High-resolution computed tomography than in spiral computed tomography (p<0.05). (2) In small airways disease group, there are different imaging conditions about tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern, bronchial mucoid impaction, bronchial dilatation: the imaging quantity in high resolution computed tomography is best, chest X-ray is less.(p<0.05); (3) In pneumono-consolidation group, there is no difference of imaging among the exam methods(p>0.05), to image the tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern ,bronchial mucoid impaction, bronchial dilatation, the differences exist, High-resolution computed tomography is better than the other methods (p<0.05).Conclusion: (1) To image pulmonary vascular and the condition of pneumono-oblique fissure, the High-resolution computed tomography is better than the spiral computed tomography. (2) To image tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern ,bronchial mucoid impaction, bronchial dilatation, High-resolution computed tomography is better than the other methods. (3) In pneumono-consolidation group, the imaging of small airways desease is also observed and the high-resolution computed tomography has more manifection than the other methods ; a large of pneumono-consolidation can be easily seen in these three methods, but the high-resolution computed tomography and spiral computed tomography are much better on manifecting internal structure than chest X-rays.
