| Abstract: | Ultrasonography utilizes high frequency sound waves between 2 and 10 MHz. Returning echos from reflecting surfaces in the body are displayed as two-dimensional images on a CRT screen. Ultrasonography is particularly useful for analysis of internal structures of parenchymal organs such as liver, spleen, kidneys, prostate and uterus, as well as fluid filled organs such as heart, urinary bladder, gallbladder, and pregnant uterus. The clinical examination is safe. Sector transducers with frequencies between 5 and 10 MHz are useful for dogs and cats. |
