Automated Volumetric Assessment by Noncontrast Computed Tomography in the Surveillance of Nephrolithiasis
Patel SR et al. – Automated volumetric measurement of renal calculi via noncontrast computed tomography is independent of specific reader and window settings. Volumetric assessment amplifies smaller linear changes over time, whereas as much as one third of cases show linear–volume measurement discordance. Volumetric assessment is therefore preferable, particularly for longitudinal surveillance of renal calculi.
