Pulmonary Embolism Clinical Trial
Official title:
Dual-Energy CT Angiography in Suspected Pulmonary Embolism: Influence of Concentration of Contrast Materials on Image Quality and Diagnostic Performance
The investigators aimed to compare the image quality and diagnostic performance of DECTPA using lower concentration iodine contrast materials and using normal concentration iodine contrast materials in the evaluation of suspected pulmonary embolism.
All patients met the inclusion and exclusion criteria will be given written informed consensus. The enrolled patients will randomly receive one of the three injection protocols: A: 30mL Iomeprol (Iomeron 300, Bracco Imaging, Milano, Italia) injected at a flow rate of 4mL/s; B: 50mL Iomeprol (Iomeron 300, Bracco Imaging, Milano, Italia) injected at a flow rate of 4mL/s; C: 50mL Ioversol (Ioversol 350, Hengrui, Jiansun, China) injected at a flow rate of 4mL/s. A and B groups are both lower concentration iodine contrast material groups, with different total iodine loads. ;
