Detailed Answer:
Hi XXXX,
Thanks for writing in to us.
I have read through your query in detail.
Please find my observations below.
1. I presume you have got a bowel resection done following which there was need for a CT scan abdomen.
2. CT scan is a procedure where pictures are generated in grey scale of various parts of the abdomen.
3. Every picture is made of multiple smaller units called pixels. There are numbers assigned to these pixels depending on the shade of grey that is present in the pixel called the HU value.
4. The CT scan machine differentiates about 1024 shades of grey and the HU value gives us information on the density of the area and what it might be.
5. It is for this reason that bones appear white and have a high HU value or grey number and air containing spaces appear dark and are assigned a negative value.
6. In your case, I suspect the grey spots might define soft tissue areas in the area of resection. The image has to be seen to tell with accuracy. However grey appearing areas in the abdomen CT might indicate soft tissue that is bowel or muscles in the abdominal wall and these structures are always grey. The fat around the bowel is dark and contains streaks of grey which are the vessels.
7. You might like to upload the picture and a short medical history for and I will confirm your doubts.
Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.
Hope your query is answered.
Do write back if you have any doubts.
