What is the reason for different apperance of glioma tumors on T1-Pre contrast MRIs?

04 April 2019 1 883 Report

I have T1-pre contrast MR images for three patients with gliomas however the tumors in the first patient looks darker while the tumors in two other patients look brighter. I wonder why?

Can anyone help me about this?

I upload the images.
