Illustration of first-pass contrast enhanced myocardial perfusion imaging showing different phases of image contrast during passage of the bolus for a subject with single vessel disease. Proton density weighted images are acquired at the start of acquisition prior to administering the contrast agent bolus. The complete time series of images are automatically processed to estimate pixel-wise myocardial blood flow maps which show regions of low flow in different color than normal flow, thereby reducing the time required to analyze the raw images. The time intensity signals represent the intensities of RV blood pool (blue), LV blood pool (red), and myocardium (black) regions. Note that flow map values are only valid for myocardium tissue and not blood pool regions or in non-tissue
