Ultrassonografia quantitativa do fígado de gatos hígidos - Nota prévia Quantitative ultrasonography of the liver in healthy cats

The ultrasonographic exam presents divergence in the interpretation of its findings, due to subjective and individual analysis. The livers of 18 healthy cats were evaluated by the ultrasonographic exam, making use of the gray-level histograms method. There were taken measures referring to the echogenicity (LMEAN), echotexture (NMOST/NALL) and echo amplitude standard deviation (SD). The mean values and standard deviations observed in this clinical assay were: LMEAN 5.6 ± 1.08, NMOST/NALL 28.31 ± 3.84 e SD 11.48 ± 1.77. The gray-level histograms method is very important for the standardizing of hepatic echogenicity and echotexture values, helping in the diagnosis and monitoring of diffuse hepatopathies.
