Method for optimizing the pre-determination of the time profile of contrast agent concentration in diagnostic imaging using a magnetic resonance system

摘要

There is provided a method of predetermining a time profile of a contrast agent concentration at a blood vessel location during an initial flooding step of a contrast agent to a blood vessel located in a region of interest with respect to a contrast agent-enhanced MRI of the region of interest. The method comprises the steps of providing a contrast bolus profile W1 according to the equation W = W2 - W1 where W1 is the first width of the contrast agent bolus profile at the first blood vessel location and W2 is the second width of the contrast agent concentration profile at the second blood vessel location in the area of interest And establishing the widening of / RTI The widening is established by determining at least one flow parameter that is dependent on at least one blood flow characteristic of the patient at its third blood vessel location and is correlated with a widening of the contrast agent profile.
