Mri scan vs ct scan

Common Questions and Answers about Mri scan vs ct scan

mri-scan

I don't have money to waste! ;) Doesn't a MRI and CT scan basically do the same thing? Wouldn't it be normal to get the CT scan first THEN the MRI if necessary?
If recurrence is suspected by can't be identified by conventiaonal imaging tests, such as CT scan, MRI or ultrasound, a PET scan may be helpful. It could be used to identify abnormal areas of uptake (absorption) that may indicate where tumour is located. However at this point, a PET scan should not be routinely used for the intial idenification of all suspected ovarian cancer.
I've had multiple CT's done, an MRI, and one PET/CT Scan. My gyn/onc in OH recommended it (the PET/CT Scan) and my gyn where I live in NC ordered it. My insurance company wouldn't approve the procedure because they said that it was still considered experimental for monitoring OVCA. Believe it or not, my gyn helped me get it done with no charge to me! The scan showed no cancer so it did ease my mind quite a bit, especially about the cyst I had on my ovary at the time.
they are going to do a ct-scan to see if i have a tumor in my head, can the ct see same as a mri. will it see all they need to see.
I just had a CT scan of my brain because I was in a stupor because my sodium was to low, my ER doc said if my altered mental status didn't improve I need an MRI and a EEg. I believe MRI displays more detail vs. a CT, and an EEg displays more functioninng abnormalites vs CT/MRI that show structural abnormalites. They also have PET, SPECT, and fMRI which also display functioning., but not as common.
Is an MRI generally more accurate for looking at the liver, gall bladder, stomach, intestines, etc. than a CT scan? 2) less radiation than CT scan? (none for an MRI I think) 3) are there no health risks from an MRI whatsoever assuming no metal objects are in the body? 4) If a CT scan is all that is available, is it worth the radiation risk? Would an abdominal CT scan be about #200 times the radiation of a chest X-ray, but about the same as a traditional GI X-ray series? Thank you.
In general, bone scans are a more precise test to measure bone damage when compared to CT scan but no test is perfect. It is true that bone scan may be less precise in lytic lesions and in these cases MRI or PET may be done. Depending upon which part of the spine was included in the MRI, some of the pelvic bones may be in the image. You may benefit from another discussion with your doctor regarding the type of pain you are having as not all pain represents bone pain.
Hi all, I have a particular worry and hoped you could provide some rational advice as doctors/radiologists/experts/fellow worriers, and it will stop me scouring the internet for all sorts of answers. I had a CT scan of my head done in 2006 (when I was 31), and another in 2009 (when I was 35) - both were needless in hindsight. Late last year, some reports came out about the risk of radiation-induced cancer being higher than originally thought.
From what I understand an MRI is much more detailed and also much more expensive. A CT scan uses radiation and an MRI uses a magnetic field. I'm not sure which is better for diagnosing cancer or tumors but I would think using the MRI would be better since it's much more detailed. I was actually wondering myself, what do you see on an MRI with contrast vs. an MRI without contrast.
He feels that the chest/back pain likely has a minor cause and is being exacerbated by my Depression, anxiety, fixation on the pain, hypochondria and somatizeation disorders I suffer from His opinion of the chest MRI vs the CT scan question I am also asking you about is that I that I don't need it at all, as they both do virtually the same things and the CAT Scan would in fact look at the chest and abdomen better, whereas for nerve, brain and spinal issues he likes the MRI for detecting thin
5 months ago i went to neurotologist and he ordered a CT Scan , Came out clear and said that everything is ok ..... My question is , Could a CT Scan detect small tumors ? Like MRI ? What should i do now ? Ps: I'm type 1 diabetic , Taking insulin and Metformin and my last A1c is 6.3 which is great , I'm diabetic since march this year... And most of the symptoms i mentioned above are 1.
I would recommend going with the latter physician's advice; a chest CT with contrast. CT will give a better view vs an xray. The other CTs you had done are old and are not focused on the chest. Curious, what did the last chest xray show?
I'm not sure I understand your question ... you've had an MRI since your initial CT scan that you were diagnosed from? So they should have a good idea of your condition. I have a pacemaker. It's MRI safe but only one machine in a 60 mile radius can scan me and it's EXPENSIVE (about $1600) so I had a CT after surgery instead, and it gave my neurosurgeon the information he needed. To a good neurosurgeon, neurologist, neuroradiologist, both are fine ... it all depends on who is looking.
Went back to my regular Dr and they told me certain scans (ct vs mri) show different things and that there must be a 'dust spot' when the scan was being done. I took it as bull and asked to look more into what was in that mri scan... They told me there is no need to investigate further. I have kaiser, that should explain some with how they treat people. I have face numbness, what do I do?
You are correct. The risks from a CAT scan are extremely low. But they exist. The basic issue here is a sober unbiased evaluation of the risks of radiation. (a) There is the school of thought evidenced by every hospital in the world that "a silly x-ray is harmless". (b) And the school of thought that every x-ray exposure has the potential to inducing a malignancy or a birth defect. The answer is not "somewhere in between". The correct answer is (b).
