OBJECTIVES There is a growing understanding of the complexity of interplay between renal and cardiovascular systems in both health and disease. The medical profession has adopted the term "cardiorenal syndrome" (CRS) to describe the pathophysiological relationship between the kidney and heart in disease. CRS has yet to be formally defined and described by(More)
Relative amounts of phosphorus-containing metabolites and sodium ions present in different regions of the in vivo rat kidney were obtained using a surface-coil probe and recently developed NMR rotating-frame methods. During altered physiologic states, changes in distribution of metabolites and sodium ions within the kidney were identified in one-dimensional(More)
A successful method of automated region-of-interest (ROI) selection by polar edge search for use in technetium-99m-diethylenetriaminepentacetate (99mTc-DTPA) renography is presented in a dog model. The accuracy of the resultant ROI was tested by comparing renal uptake within the ROI to simultaneously monitored arterial 99mTc-DTPA concentration. The(More)
