Customer Question

I have a Carotid CTA scan from a little while ago and a Carotid MRI study from last week and I want to compare them for any changes in the plaque load. I'm looking for a radiologist who can do this. Thank you

Greetings

Where is the plaque located? Is it in the internal carotid arteries?

Expert:  Nadim Al-Mubarak replied 7 months ago.

I am a Carotid expert with over 20 years experience treating carotid disease.

  • Generally, you can not compare the plaque load between these two studies. You would be comparing apples and oranges
  • But, for the clinical indications, and wether a blockage needs to be treated or observed, this question can be answered
  • I am happy to look at your CTA and MRA, if you forward the images

I am looking to see if the plaque has regressed from the time of the CTA study to the time of the MRI study. I will send you a link to the files shortly. Why is like comparing apples to oranges?

The question I have for you is:
Has the plaque regressed (reduced in size) from the time of the CT Scan (1st) to the MRI scan (2nd)
Thank you

I have not been able to open these studies. Are you able to send it here as an attachment?

Expert:  Nadim Al-Mubarak replied 7 months ago.

I understand your question very well but I tried again and have not been successful. Let me know if there is another way for me to review your studies

Customer: replied 7 months ago.
The studies combined I believe are 1gb. So I can't send them here. They have to be at a large file site like dropbox. You will need to download them to your computer and then unzip them. Depending on your download speed downloading may take awhile
Expert:  Nadim Al-Mubarak replied 7 months ago.

I see, Ok. I will try it again
