What does normal echogenicity mean?
What does normal echogenicity mean?
Echogenicity (misspelled sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
What is mild diffuse increased echogenicity of the liver?
A liver ultrasound examination is a reliable test for confirming steatosis. Fatty infiltration of the liver produces a diffuse increase in echogenicity (a bright liver) and vascular blurring due to ultrasound beam attenuation.
How is the echogenicity of the liver determined?
Normal echotexture is a smooth surface of the liver. Normal echogenicity means that the liver is reflecting the sound waves normally. A badly damaged liver is hard and doesn’t reflect sound waves well. Micronodular contours = nodules less than 3mm in diameter over the surface of the liver.
What are the micronodular contours of the liver?
Micronodular contours = nodules less than 3mm in diameter over the surface of the liver. Hepatopetal flow = blood flowing thru the portal vein towards the liver, which is normal. Hepatofugal is away from the liver and not normal.
What is the normal size of the liver in an ultrasound?
Cirrhosis = heavy scarring (fibrosis) of the liver. No steatosis = no fatty buildup in the liver. The average normal size of an adult liver based in ultrasound is 14cm plus or minus. Normal echotexture is a smooth surface of the liver.
What does smooth hepatic contour in ultrasound mean?
Nothing bad: Smooth hepatic contour means no signs of cirrhosis or mass. Echogenicity is sometimes from a vessel on end or a small hemangioma. These are not cancerous or anything to worry about. Hepatopedal means the blood flow to the liver is in the correct direction.
What does increased echogenicity mean?
Increased echogenicity means that on a sonogram study the liver had a lighter or whiter appearance than is typical. This is called fatty infiltration and can be caused by many things such as medications like cholesterol lowering drugs and many other medications.
What is mean by liver echogenic?
Echogenic Liver Echogenicity refers to the property of reflecting sound (producing an echo). An echogenic liver is a liver that reflects sound or produces an echo. This has medical relevance only to the medical imaging technique known as an ultrasound.
What is homogeneous echogenicity?
Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease and benign and malignant nodules can coexist with diffuse thyroid disease. Underlying heterogeneous echogenicity might make it difficult to differentiate between benign and malignant nodules on US.
What does increased cortical echogenicity mean?
Increased cortical echogenicity is commonly attributed to chronic kidney disease (CKD) and has been correlated with interstitial fibrosis, tubular atrophy, and glomerulosclerosis in histologic studies.
