Comparative Analysis of Maximum Renal Longitudinal Length with Positional Changes on Ultrasound with Multiplanar Reconstructed MR Image in Korean Adults

Renal size is an important parameter used for clinical evaluation of renal growth and renal abnormalities (1). The documentation of symmetric small kidneys supports the diagnosis of progressive chronic renal disease with an irreversible component of scarring. Normal kidney size suggests the possibility of an acute rather than chronic process (2). Accordingly, accurate measurement of renal size can be of importance in the diagnosis and treatment of renal diseases. As the kidneys are not parallel with the craniocaudal direction in the body, in the case of 3D CT or MR imaging techniques, the reconstruction of oblique images that match the long axis of the left or right kidney is necessary for radiologists for accurate measurement of renal length (3).
