Ventricular volumes in patients with normal and abnormal T2 weighted MRI (that is, ≥1 T2 lesion) at baseline. Ventricular volumes in patients with abnormal baseline T2 weighted MRI: comparison of those with and without gadolinium (Gd) enhancing and T1 hypointense lesions
| Normal and abnormal baseline MRI (n=55) | Abnormal baseline MRI (n=40) | |||||
|---|---|---|---|---|---|---|
| Normal MRI (n=15) | Abnormal MRI (n=40) | Gd lesions (n=15) | No Gd lesions (n=25) | T1 hypointense lesions (n=21) | No T1 hypointense lesions (n=19) | |
