Özet
Background Accurate estimation of kidney size and volume in the solitary functioning kidney is crucial because of a higher
risk of developing kidney injury. MRI is an accurate method and is suitable for kidney volume measurement. Usually, axial
axis images and measurement methods are preferred for kidney volume measurements. However, the anteroposterior diameter of the kidney is smaller than the longitudinal diameter, meaning that imaging in the coronal axis could provide needed
information in a shorter time, enabling imaging of younger patients without sedation. Therefore, the purpose of this study
was to compare coronal and axial axis kidney volume measurement methods and evaluate intra-observer and inter-observer
reliability.
Methods Axial axis T2W and coronal axis FIESTA images of kidneys were obtained with 10 mm slice thickness and no
slice gap in pediatric patients with congenital solitary kidneys. Free-hand manual tracing was used to calculate volumes in
both methods. Images were analyzed by two operators with diferent levels of experience. The expert operator computed
solitary kidney volume twice in both methods for the intra-observer reliability, while the beginner operator’s measurements
were used for the inter-observer reliability.
Results High intra-observer (0.965 for axial and 0.972 for coronal) and inter-observer reliability were revealed (0.964 for
axial and 0.963 for the coronal) for both measurement methods.
Conclusion The coronal plane volume measurement method, which has a signifcantly shorter examination and post-processing time, is a highly reproducible and reliable method that can enable volume measurement with MRI in younger children,
as the imaging time will be shortened.
