Diagnostic Value of Multi-slice Spiral CT in Pulmonary Sequestration / 实用放射学杂志

ABSTRACT

Objective To appraise the value of multi-slice spiral CT angiography in diagnosing pulmonary sequestration.Methods 6 cases with pulmonary sequestration confirmed by surgery-pathology and with complete imaging data were analysed,retrospectively.All cases were examined by multi-slice spiral CT angiography and the CT images were reconstructed including multiplanar reformation(MPR),curved planar reformation(CPR)and maximum intensity projection(MIP).Results The lesions located at the posterior basal segment of left lung in 4 cases and the posterior basal segment of right lung in 2 cases.The lesions appeared as cystic in 1,solid in 3,cyst-solid in 1 and mass mixed by multiple nodules in 1.The enhanced characteristics of lesions,abnormal supply arteries,the drained veins and its relation with the lesions were showed by CT angiography and three-dimensional(3D)reconstruction images.Conclusion The characteristics of pulmonary sequestration can be evaluated well by multi-slice spiral CT 3D reconstruction angiography.
