Renal metabolic rate of oxygen (rMRO₂) is a potentially important biomarker of kidney function. The key parameters for rMRO₂ quantification include blood flow rate (BFR) and venous oxygen saturation (SvO₂) in a draining vessel. Previous approaches to quantify renal metabolism have focused on the single organ. Here, both kidneys are considered as one unit to quantify bilateral rMRO₂. A pulse sequence to facilitate bilateral rMRO₂ quantification is introduced.

To quantify bilateral rMRO₂, measurements of BFR and SvO₂ are made along the inferior vena cava (IVC) at suprarenal and infrarenal locations. From the continuity equation, these four parameters can be related to derive an expression for bilateral rMRO₂. The recently reported K‐MOTIVE pulse sequence was implemented at four locations: left kidney, right kidney, suprarenal IVC, and infrarenal IVC. A dual‐band variant of K‐MOTIVE …
