ABSTRACT
Objective To probe the advantages and characteristics of imaging on dual-energy CT boneless and digital sub- traction brain angiography through comparative analysis. Methods Siemens 64-slice dual-source spiral CT and double high pressure syringe; The 200 patients were randomly divided into dual-energy group(n=100) and DSACT group(n=100); Every patient was injected 50 ml contrast medium and 50ml normal saline, injection rate was 4ml/s. Results The groups of cere- bra-vascular imaging without interference, and completely boneless; but experimental group has more boneless defects and vascular surface definition less. The cerebral arteries were interfered by the venous shadow in dual-energy group, and the dual-energy group received low-dose radiation. Conclusion The DSACT imaging quality is superior to dual-energy CT boneless imaging. The radiation dose of the dual -energy CT is lower than DSACT.
