Feline renal ultrasonography: Quantitative analyses of imaged anatomy

Abstract

SUMMARY Maximal kidney dimensions from serial ultrasonograms were measured in 10 healthy cats. Because clinical ultrasonographic examination is often performed in conjunction with excretory urography, the effect of radiographic contrast medium-induced diuresis on dimensional change also was evaluated. Although a slight, statistically significant increase in size was observed (compared with kidneys scanned without contrast medium), this increase could not be detected on the basis of visual image evaluation alone.
