However, in cases where CT scan detects an abnormality or if your doctor thinks that you have enough signs and symptoms which need more detailed scanning, he/she might order an MRI.

Would Ms show up on a CT scan?

CT scans may be used to exclude other causes of neurologic impairment, but they have a low positive predictive value in the diagnosis of MS; thus, the false-negative rate is high.

What symptoms do MS spinal lesions cause?

They can even show the blood vessels that feed the tumor – all without having to cut into the patient.

How small of a tumor can a CT scan detect?

The primary limitation of CT scanning is its resolution, approximately 1 centimeter. A cancer smaller than this cannot be easily detected using this technique. However, recently developed scanners such as “helical” and “spiral” CT scanners are able to detect smaller masses.
