How do the Bosniak cyst criteria differ on MRI?

For MRI, Type II are cystic masses with a thin ≤2mm wall of 3 types:
1. Thin and few septae
2. Homogeneous mass markedly increased in signal on T2 weighted image
3. Homogeneous mass hyperintense T1 weighted noncontrast image
Type IIF include those on CT and heterogeneous masses on noncontrast fat sat T1- weighted imaging
