Abstract: The present invention relates to the field of the essentials of life and, more particularly, to the field of biological analysis. More particularly it relates to a method for the analysis, detection and/or prognosis of disturbances of blood flow in the different regions of the organism, in patients capable of demonstrating alterations in blood flow in different organs of the body, in particular in coronary flow, in which the blood flow is measured before and after a physical, medicinal and/or neurosensory stimulation test, which modifies the blood flow in the region considered after administration of a tracer the fixation of which is measured, so that its elimination rate is determined with respect to a control value using calculation software. Use for testing cerebral, cardiac or tumorous vascularization disturbances.
