    Why would a doctor order an MRI without contrast?

    Even without the intravenous contrast, MRI can detect pathology in most organs and in some cases the pathology is made less visible on a contrast MRI than a non-contrast scan. For example, non-contrast scans provide greater images of blood vessel activity to detect aneurysms and blocked blood vessels.

    MRI with contrast is superior at measuring and assessing tumors. Contrast helps detect even the smallest tumors, giving the surgeon more clarity regarding the location and size of the tumor and other tissues involved. MRI images with contrast are clearer and better quality than the images without contrast.

    This means it's unlikely you'll get the results of your scan immediately. The radiologist will send a report to the doctor who arranged the scan, who will discuss the results with you.
