Abstract: Background The Peripheral Perfusion Index (PFI) has been utilized for early detection of impaired organ perfusion in order to avoid tissue hypoxia, which could lead to organ failure [1]. A decrease in effective circulating blood volume, lowering of PFI levels, can cause vasoconstriction [2]. Strong MRI magnetic field (B0) interactions with flowing blood plasma electrolytes produce a Magnetohydrodynamic voltage (VMHD) [3]. We hypothesized that a processing method which derives VMHD at different segments of the body could provide a direct indicator for PFI as well as local perfusion levels in various body regions. Existing methods for PFI estimation include Pulse Oximetry (PO) and differential temperature recordings, both of which are indirect measurements [4].
