Brief Answer:
left level nodes responding to therapy.

Detailed Answer:
Hi XXXX
Thanks for asking.
I am Dr. Jyothi BL and I will be answering your query.

Based on your clinical diagnosis and query, my opinion is as follows:

Interval resolution of metabolic activity means, the lymphnode or lymphoma metabolic activity is responding to therapy and it is reduced compared to previous scan.
The previous hypermetabolic lymphnodes activity is reduced and the lymphoma is responding to therapy.
This is occurring on the left level of 1B means the submandibular group of lymph nodes are having reduced metabolic activity compared to previous test examination.

Hope it helps.
Any further queries, happy to help again.

My previous petct scan was fdg uptake suv 5.3 with alymphnode size of 13x8mm?reactive. Is that means the size of the lymphnode reduced or the suv uptake.
For your information I am not taking any treatment my last treatment was in 2012 when I was taking retuximab.

Brief Answer:
It says reduced SUV/metabolic activity uptake

Detailed Answer:
Hi,
Standardized uptake value or SUV of 5.3 usually indicates a benign diagnosis possibly an infection or a reactive lymphnode. However, in developed countries, 2.3 SUV is often taken as a standard value and above it is considered malignant.

The present FDG PET-CT indicates the reactive lesion metabolic activity is reducing. It does not say anything about the lymph node size, but it says SUV/metabolic activity is reduced.

Any further queries, happy to help again.

My son had a diagnosis of DLBCL five months ago. He finished six courses of RCHOP on December 27, and his oncologist order a PET/CT evaluation 2.5 weeks after the completion of chemotherapy. My question: was it too soon? His PET/SCAN showed some lymphnodes with much reduced SUVs, mostly in 4 and a few higher at 6 and 8. Are these numbers to be trusted as a basis of restaging? Thank you in advance.

My brother has been diagnosed with stage 4 colon cancer with light spotting on liver on CT scan . Cancer specialist doctor has now asked for a PET CT can so that he can decide on whether or not to do surgery. I am far away from my brother.
