What is low attenuation mass?

What is low attenuation mass?

Attenuation is a feature of CT, and low attenuation means that a particular area is less intense than the surrounding. All of the malignant nodules confirmed by biopsy have low attenuation, with the exception of two which have a mixture of high and low attenuation.

What is a non enhancing cystic lesion?

In general, the terms ‘enhancing’ or ‘non-enhancing’ lesion refer to the uptake of Gadolinium-based contrast agent in the lesion. Typically, this property is assessed using a T1-weighted acquisition: Gd shortens the longitudinal relaxation rate of tissue, which causes a signal enhancement.

What is a fluid attenuation mass that is inferior and?

‘Fluid attenuation’ on CT means that the mass has characteristics of something composed of/containing fluid, which along with its smooth, well-defined margins makes it likely to be a cystic mass. However, without tissue biopsy it would be hard to tell and this is why you were referred to a surgeon.

What does fluid attenuation mean on a CT scan?

‘Fluid attenuation’ on CT means that the mass has characteristics of something composed of/containing fluid, which along with its smooth, well-defined margins makes it likely to be a cystic mass. However, without tissue biopsy it would be hard to tell and this is why you were referred…

Which is an example of a low attenuation lesion?

According to Dr. West at Cancer Grace, a low-attenuation lesion is a spot that appears on a radiographic image as less dense than the surrounding healthy tissue in that specific organ of the body. For example, a low-attenuation lesion could appear as a result of imaging on the liver, pancreas, kidney or thyroid.

Where is the expansile soft tissue attenuation mass located?

Axial contrast-enhanced CT image shows an expansile soft tissue attenuation mass centered in the right paravertebral compartment and right neuroforamen, eroding the adjacent vertebral body and displacing mediastinal contents anteriorly. Also noted is an enormous right axillary mass with faint internal septations.
