The Role of 16-slice Spiral CT Pulmonary Angiography in Diagnosing Pulmonary Embolism / 实用放射学杂志

ABSTRACT

Objective To explore the diagnostic value of 16-slice Spiral CT pulmonary angiography(16-SCTPA) in diagnosing pulmonary embolism(PE).Methods 13 patients suspected with PE were examined with 16-slice spiral CT pulmonary angiography.The volume data of all patients were reconstructed with the 3D techniques including multiplanar reconstruction(MPR) and maximum intensity projection(MIP),and CT features were analysed.Results In 13 patients,58 thrombosed pulmonary arterial branches were displayed by CT-PA,including 3 main pulmonary arteriae,18 lobar arteriae,22 segmental vessels,15 subsegmental or sub-subsegmental arteriae.Conclusion 16-slice Spiral CT pulmonary angiography is non-invasive,fast,and highly accurate method,it would be the modality of choice for the diagnosis of PE.
