Abstract
The present invention relates to improved assessment of a stenosis in a blood vessel in a body by comparing hemodynamic properties of the stenosed blood vessel with a substantially symmetric different blood vessel in the same body.
Claims20
A method for assessing a stenosis in a blood vessel in a body, said body comprising
- a first blood vessel comprising a stenosis;
- and
- a second blood vessel that is substantially symmetric to the first blood vessel, said method comprising the steps of:
- imaging the first blood vessel and second blood vessel simultaneously to obtain image data of the first blood vessel and image data of the second blood vessel;
- determining hemodynamic properties relating to a section of the second blood vessel corresponding to a section of the first blood vessel comprising the stenosis from the image data of the second blood vessel,
- determining hemodynamic properties relating to the section of the first blood vessel comprising the stenosis from the image data of the first blood vessel;
- and
- generating stenosis data based on the determined hemodynamic properties relating to the section of the first blood vessel comprising the stenosis and on the determined hemodynamic properties relating to the section of the second blood vessel corresponding to the section of the first blood vessel comprising the stenosis.
A system for assessing stenosis severity in a blood vessel in a body, said body comprising
- a first blood vessel comprising a stenosis;
- and
- a second blood vessel that is substantially symmetric to the first blood vessel, said system comprising
- an imaging system configured to simultaneously generate image data of the first blood vessel and the second blood vessel;
- and
- a processor configured to:
- determine hemodynamic properties relating to a section of the first blood vessel comprising the stenosis from image data of the first blood vessel;
- and
- determine hemodynamic properties relating to a section of the second blood vessel corresponding to the section of the first blood vessel comprising the stenosis from the image data of the second blood vessel, and
- generate stenosis data based on the determined hemodynamic properties relating to the section of the first blood vessel comprising the stenosis and on the determined hemodynamic properties relating to the section of the second blood vessel corresponding to the section of the first blood vessel comprising the stenosis.
A computer program product for assessing a stenosis in a first blood vessel in a body, said body comprising the first blood vessel comprising the stenosis and a second blood vessel that is substantially relative symmetric to the first blood vessel, said computer program product comprising instructions to execute the following steps when the computer program product is run on the computer;
- imaging the first blood vessel and second blood vessel simultaneously to obtain image data of the first blood vessel and image data of the second blood vessel;
- determining hemodynamic properties relating to a section of the second blood vessel corresponding to a section of the first blood vessel comprising the stenosis from the image data of the second blood vessel,
- determining hemodynamic properties relating to the section of the first blood vessel comprising the stenosis from the image data of the first blood vessel;
- and
- generating stenosis data based on the determined hemodynamic properties relating to the section of the first blood vessel comprising the stenosis and on the determined hemodynamic properties relating to the section of the second blood vessel corresponding to the section of the first blood vessel comprising the stenosis.
