Is Having A CAT Scan Show The Same Information That The Oncologist Gets The Same As You Get On A MRI?

Summerville, SC

I'm just wondering because I can't have a MRI due to having a Spinal Cord Stimulator implant in my back. I can only have ultrasound and CT.

No, a CAT scan (CT scan) and an MRI provide different types of information:

- CT Scan: Uses X-rays to capture cross-sectional images of organs. It is often used to check if cancer has spread to the lungs or other organs
- MRI: Uses strong magnets and radio waves to create highly detailed images of organs and tissues. It Show Full Answer

No, a CAT scan (CT scan) and an MRI provide different types of information:

- CT Scan: Uses X-rays to capture cross-sectional images of organs. It is often used to check if cancer has spread to the lungs or other organs.
- MRI: Uses strong magnets and radio waves to create highly detailed images of organs and tissues. It is particularly useful for identifying brain metastases and spinal tumors.

Each test has its specific uses depending on what the oncologist needs to investigate.

Teresa486,
I have 5 Aesculap Yasargil aneurysm clips which are non-ferromagnetic, MRI-Safe (3-Tesla or less) implants crafted from Titanium or Phynox alloy in my brain.
Anyone who has had anything implanted in their bodies should have been given cards with serial numbers, type of material used and general information pertaining to future MRI, X-ray, etc. needs.

This is a great example of where the AI got the answer wrong. While the technology behind the MR and the technology behind the CT are completely different, and that regard the AI is correct, they can garner similar information for certain types of body parts on both MR and CT. There are certain types of soft tissue, which CT is not as good at investigating, so that is why they have to also order the ultrasound with the CT. That said, under no circumstances, can you ever have an MR if there is any metal in your body…. Hence the CT, fine with metal

i am extremely happy to be eating some crow in your case sue... but yes! i would also say very lucky given how stealthy ilc can be to detect per rads, drs. & scientists

i didn't learn if you shared 1 lump or 2 - even tho i was given choice of lumpectomy [only if i agreed to the contrast mri] or mast. [then i could forgo the mri], i considered that while i was comfortable with the radio tracer for the sln since it's proven to exit quickly - i was NOT comfortable with the gad...

in a sense, this put me between a rock & a hard place for CHOICE - but finally came to my own conclusion [sans TEAM support] that due to the 2 tumors, i felt more confident with the mast.

i admire you for your conservative choice & i'm sure yall will be watching - if there's anything good about ANY kind of cancer, lob is supposed to be a slower grower than ductal

thank you for sharing this and hope we can keep in touch to share our lob stories...

also, i may have to come be your new bff if you play the lotto -lol🙂

have a beautiful weekend sue

So, what you are saying is that if you have IDC, you can have MRI without the gadolinium contrast and still get test results.

But, if you have ILC, you need to have the gadolinium as otherwise I LC can’t be seen.
But the contrast is toxic and may have side effects.

Then you said that they are going back to other earlier contrast types for ILC?

The FDA is approving a new contrast for July. I do not know if it is another form of gadolinium though. Obviously it does not have years of testing.

Yesterday my radiation oncologist said that MRI’s would not work without the contrast dye and are useless when I asked if MRI could be done without contrast.

Plus, two months ago, my medical oncologist advised against any MRI’s unless absolutely necessary as when they found something..
She mentioned the toxicity and health issues with it…
