What are the odds that a CT scan with and without contrast missed a brain tumor?

1 doctor agrees

In brief: Brain tumor

The odds are not very high but if concerns persist that something could have been missed, a brain MRI with contrast is recommended.

MRI scans are more sensitive than CT scans for detecting brain tumors
Dr. Steven Beer
CT scans have less resolution compared to MRI's. Lesions small as 5mm can be seen if the tumor tissue is different than surrounding tissue.

In brief: Overall mri better

It depends whether or not the scan was done with contrast.
Chances are low that anything large was missed although smaller lesions go unseen from time to time. Mri is overall more sensitive for showing tumor especially when performed with gadolinium .Unless you are specifically looking for calcium or an MRI is contraindicated , MRI should be the procedure of choice.
