1. A method, comprising: obtaining imaging data perfusion with contrast at least two regions of vessels, one of which is disposed downstream of the other, and at least one of the tissue, which takes blood from the circulatory system of the subject to be scanned , determining the time difference between the peaks of flow of contrast agent at least two regions vessels based on the image data determining absolute perfusion of the tissue based on the image data calculated normalized value based on absolute perfusion and the perfusion time difference and displaying the normalized value perfuzii.2. . A method according to claim 1, further comprising the steps of: forming a behavior of the first flow of contrast agent for a first of the at least two areas of vessels, determining a first time of peak contrast for the first of the at least two regions vessels based on the first behavior shape behavior second flow of contrast agent for the second of the at least two areas of vessels, determining a second time peak contrast for the second of the at least two areas on the basis of vascular vtorogopovede Ia, determining the time difference based on the first peak time and second staining time of peak kontrastirovaniya.3. The method of claim 2, further comprising the step of:. Determining the time difference based on the mean transit time of the first staining time and the average value of the second transition kontrastirovaniya.4. The method of claim 2, further comprising the step of:. Determined1.
