MRI vs PT scan

Continuing the discussion from MRI for lobular cancer:

Hi, new to posting and have a question on testing; I meet with my oncologist next week.
I have IDC with lobular features, tumor was 5 cm and 10/19 + lymph nodes.
ER+ PR+ HER2-.
I had 5mo chemo (cytoxan/adriamycin then taxol) followed by radiation.
I have been on Femara for 2 yrs in Nov, and 2 yr Verzenio in Feb.

I meet with my oncologist and don’t understand why first short term oncologist did Pet scans early on, and current oncologist for last 1.5 yrs prefers CT scans.
Hi often and what type of scans should I be requesting. I want to be proactive, not wait to find out it has spread to bone or organs.
Recent slight nausea past month that I have never had. and left mastectomy arm/armpit has pains that Is probably just surgery related but never know. Currently 3c so should I request scans now, it’s been a year, the plan is ct in Nov for lung that had a tiny something to keep eye on and Ct in Feb for chest/ab I believe.
I want the best scan to see what’s going on; they missed my initial diagnosis saying in situ and a small lob and did breast saving surgery before realizing how large tumor was. Thanks

Hi @lb_hopeful

Not sure what a pet scan is.
The CT scan looks at bone and soft tissue
The MRI looks in more detail at soft tissue.
Then there are different types of bone scans.
I think the CT is the one that covers off checking most things at once, they use the contrast dye to check for odd things showing up. Then I think they go to the other scans for the in-depth detail when they know what they’re wanting to investigate.

Only going off my experiences.

Take care xxx
