The study on the evaluation of large shadow of pneumoconiosis with average density projection
LI Weiwei
Abstract：Objective The value of CT average density projection(AIP)in the evaluation of pneumoconiosis was discussed by measuring chest X-ray,dr chest X-ray,CT coronal average density projection(AIP)and coronal plane multi-plane reconstruc-tion(MPR).Methods The large shadow cases of pneumoconiosis were reviewed, and the large shadow of chest X-ray, dr chest,coronary CT average density projection(AIP)and coronal plane reconstruction(MPR)were measured and analyzed.Re-sults In the evaluation of big shadow,there are no significant differences in the three methods of high-kV X-ray chest X-ray,dr chest radiography and CT coronal plane density projection(AIP),and there are significant differences in MPR data.Conclusion The CT coronal plane average density projection(AIP)can be used to evaluate the large shadow of pneumoconiosis,and MPR is not reliable in the evaluation of large shadow.AIP is superior to MPR in evaluating the size and shape of large shadow of pneumo-coniosis.
