Histogram of ultrasound in diagnosing and grading of fatty liver / 中国医学影像技术

ABSTRACT

Objective To explore the value of the histogram of ultrasound in diagnosing and grading of fatty liver. Methods Ninety subjects were enrolled in normal group, light or moderate to severe fatty liver group (each n=30), respectively. All the subjects underwent histogram of ultrasound of the liver, kidney, spleen and right hepatic vein (RHV), and the ratio of histogram M value of different area were analyzed. Results Statistical differences of the ratio of histogram M value of anterior hepatic tissue of kidney and kidney (AntK) between normal group and two fatty liver groups were detected (P<0.05). The ratio of histogram M value of anterior hepatic tissue of RHV and RHV (AntV) between the normal group and moderate to severe fatty liver group, as well as the light and moderate to severe fatty liver group had statistical differences (P<0.05). When 0.97, 0.78 were used respectively as the critical value of the ratio of histogram M value in diagnosing and grading of fatty liver at AntK and AntV, the sensitivity was all 80.00% and 80.00%, specificity was 85.00% and 70.00%, respectively. Conclusion The ratio of histogram M value of AntK, AntV can be used as the referent index in diagnosing and grading of fatty liver.
