Diagnostic Value of Multi-Slice CT Pulmonary Angiography in the Diagnosis of Pulmonary Embolism: An Investigation of Optimal Scanning Protocols in Terms of Image Quality, Contrast and Radiation Doses

Abstract

This thesis investigates the feasibility of low-dose multi-slice CT pulmonary angiography in the diagnosis of pulmonary embolism based on experiments on a 3D printed realistic pulmonary artery model and patient data analysis. The research findings show that significant dose reductions in radiation dose and contrast medium have been achieved using low-dose CT pulmonary angiography protocols without affecting diagnostic image quality.
