Patent ID: 8208699

Claim:
A method comprising: administering a contrast agent test injection to a patient according to a first injection profile prior to a selected diagnostic imaging procedure; defining first and second regions of interest of the anatomy of the patient; establishing a first desired time enhancement profile at the first region of interest and a second desired time enhancement profile at the second region of interest; establishing a desired multiphasic injection profile for administering contrast agent to the patient, wherein the desired multiphasic injection profile is established based on the first and second desired time enhancement profiles, a first injection profile used to administer contrast agent to the patient, and measured time enhancement profiles at the first and second regions of interest resulting from the administration of the contrast agent to the patient according to the first injection profile; wherein establishing the desired patient injection profile includes: establishing a desired injection profile for enhancing the first region of interest, establishing a desired injection profile for enhancing the second region of interest; and wherein the desired patient injection profile for administering contrast agent to the patient is a multiphasic injection profile which includes the first desired injection profile for enhancing the first region of interest and the second desired injection profile for enhancing the second region of interest.
