Systems and methods to map autoregulation of the kidney using magnetic resonance imaging

One or more non-transitory machine-readable storage media for mapping autoregulation of one or more organs outside a central nervous system of a subject using magnetic resonance (MR) imaging, the one or more non-transitory machine-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause a system to:

• receive a time series of MR images acquired using a non-contrasted resting state MR imaging to detect physiological fluctuation slower than a respiratory rate of the subject, and an imaging region of the MR images includes the one or more organs outside the central nervous system of the subject;
• analyze the time series of MR images along a temporal dimension;
• identify features associated with the autoregulation of the one or more organs in voxels of the MR images, based on the analysis;
• generate at least one of a map or a metric of the autoregulation, based on the identified features;
• and
• output at least one of the map or the metric.

A computer-implemented method of mapping autoregulation of one or more organs outside a central nervous system of a subject using magnetic resonance (MR) imaging, the method comprising:

• analyzing a time series of MR images along a temporal dimension, wherein the time series of MR images were acquired using a non-contrasted resting state MR imaging to detect physiological fluctuation slower than a respiratory rate of the subject, and an imaging region of the MR images includes the one or more organs outside the central nervous system of the subject;
• identifying features associated with the autoregulation of the one or more organs in voxels of the MR images, based on the analysis;
• generating at least one of a map or a metric of the autoregulation, based on the identified features;
• and
• outputting at least one of the map or the metric.
