Can ultrasound images determine if fluid is present in a certain area of the body?
Yes, sonography is a great method for detecting and measuring fluid. For instance, in obstetrics, sonographers can look to see how much amniotic fluid is present. A doctor may also order a sonogram to make sure the kidneys and bladder are functioning properly, determining if the fluid from the kidneys is emptying into the bladder normally. Other examples where fluid comes into play is when the physician ordering the ultrasound is looking for fluid on the brain of a neonate, fluid in the lungs (pneumonia), fluid in an appendix (appendicitis), fluid around organs (like liver cirrhosis), fluid backed up into the kidneys, and fluid around the heart. Also, vascular studies determine the velocity and turbulence of fluid coursing through veins and arteries.
