MRI or CatScan as follow up imaging for metastatic liver tumor?

I have metastatic liver cancer I have been told MRI is the best scan for the liver I never had a CT for my liver

MRI for my liver mets

My oncologist orders CT scans with contrast every 3-4 months!

My oncologist orders CgA tests and CT scans with contrast every 3-4 months

I was having MRI abdomen and CT Chest about every 3 months, once I started CapTem it's been CT for both now

CT scan with contrast every 4 - 6 months

@spendrous: I have NET Specialist Oncoligist at City of Hope treating my sm. intestine primary with liver metastases. He recommends MRI with/without contrast “Evoist” (this contrast medium is premium in detailing tumor size). I have also learned that you get best imaging when at a cancer facility due to the equipment and Radiologist’s cancer experience. Also MRI’s have no radiation exposure; although it is necessary to have a recent cleared Creatinine blood report (to insure kidneys are okay). Hope this helps!

MRI every 3 months w/ and w/o contrast substance. I've been told safer and better for liver.

My husband has multiple NETs in the liver and the primary site is in the small intestine. He started with a MRI that was very useful in determining the numbers and sizes of the tumors, but since then he has been getting CT scans every 3 months with contrast. He had one specialized CT scan (CT enterography https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/ct-enterography) at Johns Hopkins, which is great for viewing details of the small intestine.

I recently asked a NET specialist this question after hearing a surgeon favor MRI in a LACNETS video. The oncologists answer was a) MRIs will be needed by a surgeon before they operate and precision is important b) if you are monitoring change in your tumors over time then CT works well particularly if you have the same parameters (equipment, contrast, reading radiologist if possible c) A CT means less time in a tube, some people hate lying in an MRI for an hour d)CT is cheaper. The question of exposure to radiation is worth exploring with your oncologist. Some centers actually keep track of how much radiation you have had but this gets tough if you use multiple health systems. I thought MSK published a useful discussion of the topic:
