My brother has been diagnosed with some type of a mass in the area where his brain and spinal cord meet.....he is going to have another MRI where they are going to use some dye.....what will this MRI be able to tell and is a second opinion a good thing to do? Can this MRI tell if the mass is a tumor? malignant or banigne? this is all new to us so we are really in need of some clarifying direction. Some of the difficulty for us is that we are on opposite sides of the country so all of our time having this explained is all second hand. Thanks for you anticipated help!
An MRI looks at slices of the brain under different radio wave intensities.A contrast enhanced study, in addition to the regular MRI study, may be able to help the radiologist/neurologist come up with a differential of what the "mass"could be. Certain tumors will take up the contrast others will not; certain tumors can be diagnosed by their MRI characteristics ,therfore, you may have an answer (malignent or benign). In other cases, the differential may be larger and a biopsy may need to be done to confirm the diagnosis. Other than tumors, massed can be caused by vascular malformations, abscesses, and cyst. Good Luck.
