Ultrasonographic texture analysis of parenchymatous organs by the four‐neighborhood‐pixels algorithm: clinical experiment.

The parenchyma of organs such as liver, thyroid, and mammary gland during climacterium have common ultrasonographic textural features, which together form what we call small‐dot‐structure texture. To study this texture we designed the 4‐neighborhood‐pixels algorithm, an ultrasonographic texture analysis algorithm. The objective of this study was to confirm whether the 4‐neighborhood‐pixels algorithm can reflect the features of small‐dot‐structure texture.
