MRI without contrast?!

Hi! I have already had one MRi with contrast which showed lesions on my brain. My new neuro has requested another mri, this time of my spine but he said he would do it without contrast?! Do lesions show without contrast?! Any advice would be great!

Leisons show thing the dye shows the activity I just had brain n spine MRI with dye this week

Ah I see! That would make sense thank you!

Lol I really need to proof Read Think not thing lol But you got the idea about what I was saying x
