FIG 1. Group 1. MR images obtained 2 hours after cat brains were embolized with triolein show type 1 (solid arrow) and type 2 (open arrows) lesions. Type 2 lesions are bigger than type 1 lesions.
A, T2-weighted (3000/96/2 [TR/TE/NEX]) image. Type 1 and type 2 lesions are hyperintense.
B, Contrast-enhanced T1-weighted (320/30/2) image. Type 1 lesions show mild enhancement. Type 2 lesions show enhancement.
C, Diffusion-weighted image. Type 1 lesions are hyperintense. Type 2 lesions have isointensity or slight hyperintensity.
D, ADC map. Type 1 lesions are hypointense. Type 2 lesions are isointense.
