1. A method for providing information determinative of an amount and presence of vascular congestion in a patient using magnetic resonance signals, comprising the steps of:
placing the patient into a magnetic resonance imaging apparatus capable of obtaining images in an upright, Trendelenburg, prone and supine postural positions;
obtaining magnetic resonance signals of vasculature of the patient's organ without using hyperpolarized gas;
processing the magnetic resonance signals to obtain magnetic resonance image data;
processing the image data to determine one or more measures of anterior/posterior signal gradation, superior/inferior signal degradation and mean signal-to-noise; and
determining the postural dependence of the presence and amount of vascular congestion based on the one or more of the determined measures of anterior/posterior signal gradation, superior/inferior signal degradation and mean signal-to-noise.
