“…Recent works have shown that 3D sonography can be used to measure renal volume with high accuracy, 4 – 9 reducing volume errors and interobserver variations 10 . A study by Kim et al, 4 which verified the value of renal volume measurement by 3D sonography with a matrix transducer, revealed that the limits of agreement (−9.7% to 5.1%) between the 3D sonographic and tomographic voxel count method were low enough to justify the use of the 3D sonographic technique described to determine renal volume in clinical practice.…”

“…By contrast, ultrasound is widely available and inexpensive, from which the volume of each kidney can be approximated by measuring its three orthogonal axes using an ellipsoid formula (ultrasound ellipsoid), providing a simplified and more rapid but less accurate alternative (16). The availability of three-dimensional (3D) ultrasound using specialized transducers in most tertiary care radiology departments provides a promising tool for clinical volumetric measurements and has been evaluated for TKV quantification in patients without ADPKD (17,18). The accuracy of TKV measurements by 3D ultrasound with manual segmentation versus ultrasound ellipsoid was also assessed in the pediatric ADPKD population (19).…”

Background and Objectives: Total kidney volume (TKV) is a validated prognostic biomarker for autosomal dominant polycystic kidney disease (ADPKD). TKV by magnetic resonance imaging (MRI) and manual segmentation is considered the "reference standard", but is time-consuming and not readily accessible. By contrast, 3-dimensional ultrasound (3D ultrasound) provides a promising technology for TKV measurements with unknown potential. Here, we report a comparative study of TKV measurements by 3D ultrasound vs. the conventional methods by ultrasound ellipsoid and MRI ellipsoid. Design, setting, participants, and measurements: Single-center prospective study of 142 patients who completed a standardized 3D ultrasound and MRI. TKV by 3D ultrasound and ultrasound ellipsoid were compared to those by MRI. We assessed the agreement of TKV measurements by Bland-Altman plots and misclassification of the Mayo Clinic Imaging Classes (MCIC) between the different imaging methods, and prediction of MCIC 1C-1E by average ultrasound kidney length >16.5 cm. Results: Compared to MRI manual segmentation, MRI ellipsoid, 3D ultrasound, and ultrasound ellipsoid underestimated TKV (mean difference: -3.2%, -9.1%, and -11.0%) with MCIC misclassified in 11%, 21% and 22% of patients, respectively; most misclassified cases by MRI ellipsoid (11/16), 3D ultrasound (23/30), and ultrasound ellipsoid (26/31) were placed into a lower MCIC. Prediction of the high-risk MCIC (1C-1E) by MRI ellipsoid, 3D ultrasound, and ultrasound ellipsoid all yielded high positive predictive value (96%, 95%, 98%), and specificity (96%, 96%, 99%). However, both negative predictive value (90%, 88%, 95%) and sensitivity (88%, 85%, 94%) were lower for 3D ultrasound and ultrasound ellipsoid compared to MRI ellipsoid. An average ultrasound kidney length >16.5 cm was highly predictive of MCIC 1C-1E only in patients aged <45 years. Conclusions: TKV measurements in ADPKD by 3D ultrasound and ultrasound ellipsoid displayed similar bias, variability, and are less accurate than MRI ellipsoid. Prediction of high-risk MCIC (1C-1E) by all three methods provides high positive predictive value, but ultrasound ellipsoid is simpler to use and more readily available.

“…In theory, the propagation speed of shear waves is proportional to the density of tissues and the shear modulus in completely uniform and isotropic targets. ARFI has been most commonly used to detect liverrelated diseases, but it is also used to detect pancreas-related diseases, among others ( 10 Su et al, 2018; 11 Brancaforte et al, 2011).There is no study for the signi cance of ARFI, 3d ultrasonography 84 and other ultrasonography imaging methods in the detection of early chronic kidney disease. This is the rst study to prove the relationship between the prolongation of renal interlobar artery AT and chronic renal injured.…”

Objective: To explore of ultrasound combined with renal pathology score, and compare the application value of elastography, two-dimensional (2D) ultrasound, three-dimensional（3D） ultrasound and other ultrasound imaging methods in early chronic kidney diagnosis.Methods: Combined ultrasound and pathological scores. A retrospective analysis of 118 patients with chronic kidney disease examined in the department of nephrology of the author's hospital. 36 healthy who were normal in the same period were selected as the control group. Combined with the left kidney pathology score and multi-factor logistic regression analysis to evaluate independent predictors of early pathological injured in CKD, ROC curve analysis to evaluate the diagnostic efficacy of each ultrasound index. Statistical evaluation: The difference was statistically significant (P <0.05).Results: In patients with severely injured CKD, renal length, three-dimensional kidney volume, Renal interlobar artery RI, and AT all appear to be effective predictors. Among patients with moderate injured, only AT and RI were effective predictors. Among patients with mildly impaired CKD, AT has the highest diagnostic efficacy, but SWV has the highest sensitivity (83.8%) for detecting mild renal injured. The results confirm that the Renal interlobar artery AT is the strongest independent predictor of CKD injured.Conclusion: The results confirm that the Renal interlobar artery AT is the strongest independent predictor of CKD injured.

Abstract: Three-dimensional US is a valuable technique for monitoring renal volume, whereas MSCT may be reserved for assessing renal anatomy and relationships with neighbouring organs.
