Resumo

OBJECTIVESTo evaluate the splenic stiffness of healthy adult cats using acoustic radiation force impulse elastography to determine the quality (greyscale images and tissue deformity) and quantity (shear velocity) standards. METHODSFifteen healthy, adult shorthair cats were selected. The echotexture, echogenicity, size and edges of the spleen were assessed via mode-B ultrasound. Using qualitative elastography, specific portions of the spleen were evaluated according to homogeneity, presence of deformities and white and dark regions. The shear velocities in different portions of the spleen were quantitatively evaluated. RESULTSThe echotexture, echogenicity, size and edges of the spleen were normal on B-mode ultrasound in all cats. On qualitative elastography, the evaluated splenic portions were not deformable, and the images presented as homogeneous dark areas. On quantitative elastography, the mean shear velocity values were 198m/s for the head portion, 177m/s for the body portion and 203m/s for the tail portion. These were not significantly different. CLINICAL SIGNIFICANCEQuantitative and qualitative acoustic radiation force impulse elastography of the spleen in healthy adult cats was easily implemented and this study may provide baseline data for this organ to allow the future use of this technique in evaluating cats with splenic disease.
