has anyone had a cat scan that showed nothing,then had an mri that showed something?

[Pazstan]

From my boyfriend Richard, who is a Radiographer, yes this is quite possible as CT and MRI are different types of imaging modality. CT uses x-rays, and MRI uses magnetism. Some things will show up on both scans and some will be more evident on one rather than the other because they work differently.

The explanation then gets too technical for me to understand, so this is only semi-helpful I'm afraid!

That's interesting, can a radiographer tell if the brain is abnormal?

[Pazstan in reply to AnthonyMs]

A radiographer would take the image, and should be able to see broad areas of damage. The image would be passed on to a radiologist, preferably a neuroradiologist to interpret fully and detect the subtleties and complexities of the damage. This takes years of experience. I hope this helps a bit.

Ah thanks, I think I was mixing up radiologist with radiographer. I have an MRI scan and have always wanted a second opinion on what damage I have.

yes, I had a number of scans which did not show up a tumour the size of a gold ball only the MRI scan showed the tumour

i had ct scan which showed a ruptured aneurysm when i was rshd to hospital in july . i then had another ct scan bout 3 mnths later,and another 1 last time i was tken in , but last time the dr who i saw said tht the ct was ok but had to have a lumber puncture as if i had a bleed under the plate it wld not show on ct scan , luckily fr me it was all ok .

Yes, when I collapsed I had a CT scan at my local hospital that didn't show anything so they did a lumbar puncture which detected blood. I was transferred to a specialist neurology department at another hospital and the MRI scan showed where the ruptured aneurysm was before they operated. As mentioned in a prior answer CT scans do not show as much detail as MRI scans.
