ULTRASOUND

Ultrasound can be useful in the diagnosis of many conditions, such as tumors, cysts, congenital malformations, and pregnancy. It is a noninvasive imaging test that allows for the visualization and evaluation of internal organs and tissue. Sound waves are used to image solid or fluid-filled structures, such as the heart, liver, gallbladder, spleen, kidneys, and urinary bladder. Structures that contain air, such as the lungs, stomach, and intestines, cannot be seen well by the ultrasound because air reflects rather than conducts sound waves. This is one reason that radiographs (Xrays) and ultrasound are often used to complement one another. Ultrasound allows the veterinarian to evaluate the architecture of many abdominal organs without the need for invasive surgery. It may be used to guide the veterinarian in the acquisition of tissue or fluid samples for further diagnostic tests. Measurements of heart wall thickness, heart chamber size, and strength of heart contraction can be determined in order to evaluate heart function and define treatment recommendations. Images from complex cases can be forwarded to a radiologist or other specialist for interpretation and consultation.
