Optimization of DE-CTPA Images and Diagnostic Pathway: Using Low Concentration Iodine Contrast Material

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

Clinical Trial Summary

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.

Clinical Trial Description

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. ;
