Bilateral low SWI signal along the lateral aspect of the putamen is present. Putaminal rim sign on 1.5 T T2 weighted images is also seen, better on the left, as a thin band of high signal.
The left putaminal SWI signal is arguably darker than globus pallidus and red nuclei.
Darker putaminal signal on T2 sequence, but subtle. Putaminal volume loss is difficult to judge.
