NON-INVASIVE QUANTIFICATION OF CORONARY ARTERY FRACTIONAL FLOW RESERVE USING MRI |
| 摘要 |
A system for quantifying a fractional flow reserve (FFR) in a mammalian subject comprises implementing a multi-dimensional phase-contrast magnetic resonance sequence using an MRI scanner to scan a volume of interest (VOI) in the mammalian subject. The VOI comprises at least a portion of the mammalian subject's heart, one or more blood vessels, or both. A pressure gradient within a blood vessel segment of interest within the VOI is determined based on the implemented multi-dimensional phase-contrast magnetic resonance sequence. The determined pressure gradient is correlated to an FFR value. |

1. A method for quantifying a fractional flow reserve (FFR) in a mammalian subject, comprising:
implementing a multi-dimensional phase-contrast magnetic resonance sequence using an MRI scanner to scan a volume of interest (VOI) in the mammalian subject, wherein the VOI comprises at least a portion of the mammalian subject's heart, one or more blood vessels, or both; and determining, via one or more processing units associated with the MRI scanner, a pressure gradient within a blood vessel segment of interest within the VOI based on the implemented multi-dimensional phase-contrast magnetic resonance sequence, the determined pressure gradient being correlated to an FFR value. |
