“…In the present study, the mean SWV of the renal cortex was 2.36AE0.67 m/s, corresponding with figures cited by Guo et al 30 and He et al 29 (2.15AE0.51 m/s and 2.35AE0.29 m/s, respectively) but conflicting with a value reached by Cui et al (1.59AE0.14 m/s). 28 Factors that may influence the SWV of the renal cortex have seldom been reported.…”

“…Displacement amplitudes are higher in soft materials (manifested as low SWVs) and lower in hard materials (yielding high SWVs). 26,27 To date, very few imaging studies of the kidney have involved ARFI technology, and these few are largely limited to chronic kidney diseases or renal allografts 28,29 ; however, the reproducibility of ARFI in assessing renal cortical stiffness has been documented elsewhere 28,29 and in this investigation. Only one similar in vivo study is known, where ARFI elastography was engaged to diagnose just 13 renal lesions (eight ccRCCs, one cRCC, two pRCCs, two haemorrhage cysts).…”

“…Several previous studies have analysed SWV values in the kidneys of both healthy volunteers and renal allograft recipients, 29,30 creating controversy over the range of SWV values for the normal renal cortex. In the present study, the mean SWV of the renal cortex was 2.36AE0.67 m/s, corresponding with figures cited by Guo et al 30 and He et al 29 (2.15AE0.51 m/s and 2.35AE0.29 m/s, respectively) but conflicting with a value reached by Cui et al (1.59AE0.14 m/s).…”

“…Currently, 1 H-MRS is considered the gold standard for determining liver fat content [10,11] . In this study, the hepatic/renal ratio and hepatic echo-intensity attenuation rate were highly correlated with 1 H-MRS liver fat content; suggesting that these methods could also accurately assess liver fatty content as well.…”

AIM:To establish and validate a simple quantitative assessment method for nonalcoholic fatty liver disease (NAFLD) based on a combination of the ultrasound hepatic/renal ratio and hepatic attenuation rate. METHODS:A total of 170 subjects were enrolled in this study. All subjects were examined by ultrasound and 1 H-magnetic resonance spectroscopy ( 1 H-MRS) on the same day. The ultrasound hepatic/renal echointensity ratio and ultrasound hepatic echo-intensity attenuation rate were obtained from ordinary ultrasound images using the MATLAB program. RESULTS:Correlation analysis revealed that the ultrasound hepatic/renal ratio and hepatic echo-intensity attenuation rate were significantly correlated with 1 H-MRS liver fat content (ultrasound hepatic/renal ratio: r = 0.952, P = 0.000; hepatic echo-intensity attenuation r = 0.850, P = 0.000). The equation for predicting liver fat content by ultrasound (quantitative ultrasound model) is: liver fat content (%) = 61.519 × ultrasound hepatic/renal ratio + 167.701 × hepatic echo-intensity attenuation rate -26.736. Spearman correlation analysis revealed that the liver fat content ratio of the quantitative ultrasound model was positively correlated with serum alanine aminotransferase, aspartate aminotransferase, and triglyceride, but negatively correlated with high density lipoprotein cholesterol. Receiver operating characteristic curve analysis revealed that the optimal point for diagnosing fatty liver was 9.15% in the quantitative ultrasound model. Furthermore, in the quantitative ultrasound model, fatty liver diagnostic sensitivity and specificity were 94.7% and 100.0%, respectively, showing that the quantitative ultrasound model was better than conventional ultrasound methods or the combined ultrasound hepatic/renal ratio and hepatic echo-intensity attenuation rate. If the 1 H-MRS liver fat content had a value < 15%, the sensitivity and specificity of the ultrasound quantitative model would be 81.4% and 100%, which still shows that using the model is better than the other methods. CONCLUSION:The quantitative ultrasound model is a simple, low-cost, and sensitive tool that can accurately assess hepatic fat content in clinical practice. It provides an easy and effective parameter for the early diagnosis of mild hepatic steatosis and evaluation of the efficacy of NAFLD treatment.
