A parameter compilation memory (62, 114) stores patient physiological information and contrast agent arrival or uptake times (tD, tA, tV) from past patients. A triggering or synchronizing window processor (64, 112) sets a triggering window, i.e. estimates the arrival time, based on the past patient information. A subject (16) disposed within an imaging region (12, 90) is injected with a contrast agent (66). Arrival of the contrast agent in the imaging region is detected (72, 110) with a real time tracking method. Diagnostic imaging is commenced on the first to occur of the detection of contrast agent arrival within the window and the end of the triggering window. The uptake times for the subject (16) are compared to those stored in the memory (62, 114) and analyzed to propose a diagnosis.
