Metabolic diseases

A free gallery of high-resolution, ultrasound, color doppler and 3D images

Ultrasound images of metabolic disorders of the liver:

Normal liver:

In this sonographic image, note the normal echogenicity of the liver which is almost isoechoic with the parenchyma of the right kidney.

Diffuse fatty change of liver:

In this ultrasound image of the liver there is diffuse increase of liver echogenicity. The liver appears markedly hyperechoic as compared to renal cortex.

Diffuse fatty liver with focal fatty sparing:

In these 3 ultrasound images there is diffuse fatty change of liver with focal fatty sparing in the periportal region, just anterior to the porta hepatis. This is a typical site of focal fatty sparing. This is seen as a small hypoechoic region. Images taken with a Pie Scanner 100 Falco, by Dr. Joe Antony.

Focal fatty change of liver:

The above ultrasound image (left) shows a hyperechoic lesion of 4 x 3 cms. in the periphery of right lobe of liver. Color doppler scan shows absence of mass effect (vessels are not displaced by the lesion). This suggests focal fatty change of liver. Such lesions may change rapidly over time. Images taken using a Medison SA 8000 color doppler machine, courtesy of Dr. Arun Mahajan, Delhi, India.
