Do I need a comma after round?

Question

There is a 1 cm round, low attenuation lesion within the posterior segment of the right lobe.

Answer 1

Debra, 

 

I would suggest wording your sentence this way: "There is a low attenuation lesion that is 1 cm round within the posterior segment of the right lobe."

 

Though this sentence is a bit longer than your original sentence, it flows better. It is easier to understand. 

 

Hope this was helpful! Always happy to provide assistance with writing and editing!

 

Best,
