What does homogeneous liver mean?
Normal liver echogenicity is homogeneous, with fine echoes. 1 One of the main causes of heterogeneous echogenicity of the liver is chronic liver disease/cirrhosis (Figure 1 of the supplementary material). Other common conditions leading to heterogeneous echogenicity are patchy steatosis and diffuse tumor infiltration.
What is a heterogeneous liver mass?
Benign tumors of the liver are a heterogeneous group of lesions whose detection has greatly increased because of the widespread use of imaging techniques. Only a few types, such as cavernous hemangiomas, focal nodular hyperplasia (FNH), hepatic adenoma (HA), and cysts, are frequent enough to be of clinical importance.
What causes increased Echotexture of liver?
The most common cause of hyperechogenic liver (increased liver echogenicity compared with the renal cortex) in routine practice is steatosis, otherwise known as “fatty liver”. This can be either diffuse or focal.
What does homogeneous in Echotexture mean?
Echotexture (echoes distribution) Homogeneous: uniform appearance of the thyroid parenchyma. Heterogeneous: non-uniform appearance of the parenchyma, due to an irregular echo pattern showing numerous micro-nodules or echogenic septa.
What is homogeneous in ultrasound?
Summary. • Organs and structures are characterized based on the amount of echoes they generate (echogenicity) and how equally distributed these echoes are in soft tissue (homogeneity).
What is a focal mass?
Description. focal liver lesions are abnormal solid or liquid masses differentiated from normal liver through cross-sectional imaging 1,2. usually detected incidentally via imaging due to unrelated symptoms. typically clinically silent but large lesions may be associated with right upper quadrant abdominal pain.
What is a focal lesion?
Focal lesions are circumscribed areas of injury to brain tissue following brain injury. Such lesions may be created when an object penetrates the skull and directly injures an area of the brain. In closed head injury, such lesions are usually associated with vascular damage, such as contusions or hemorrhages.
What is meant by homogeneous Echotexture?
There are three categories of tissue composition according to the BI-RADS lexicon 1: homogeneous background echotexture – fat. the bulk of the breast is comprised of fat lobules and uniformly echogenic bands of connective tissue.
What does Echotexture of the liver mean?
Definition. The appearance of the liver in sonographic images is normally uniform. This term applies when there is an irregular or non-uniform appearance of the liver parenchyma in liver sonography. [ from HPO]
What can be found in a liver ultrasound?
A liver scan may be done to check for diseases such as liver cancer , hepatitis , or cirrhosis . Lesions such as tumors, abscesses, or cysts of the liver or spleen may be seen on a liver scan.
What can an ultrasound of the liver detect?
Although a liver ultrasound is intended to identify liver conditions specifically, an abdominal ultrasound in general can diagnose a variety of abdominal organ conditions, such as: 1 Abdominal pain. 2 A distended — or enlarged — organ. 3 Abnormal function of the liver. 4 An abdominal aortic aneurysm. 5 Gallbladder stones. 6 (more items)
What does a homogeneous echotexture of the liver mean?
When scanned using an ultrasound probe, homogenous echotexture means the liver tissue appear uniform on the reflected sound waves. This could mean the liver is entirely normal or entirely abnormal.
Can ultrasound be used to assess fatty liver and bile duct dilatation?
These goals can be achieved using ultrasound methods based on conventional sonography, contrast-enhanced sonography and elastography. The assessment of fatty liver and bile duct dilatation using ultrasound reaches satisfactory levels of sensitivity and specificity.
What does increased liver echogenicity at ultrasound examination indicate?
Increased liver echogenicity at ultrasound examination reflects degree of steatosis but not of fibrosis in asymptomatic patients with mild/moderate abnormalities of liver transaminases Dig Liver Dis. 2002 Jul;34(7):516-22.doi: 10.1016/s1590-8658(02)80111-6.
