From: Decreased brain venous vasculature visibility on susceptibility-weighted imaging venography in patients with multiple sclerosis is related to chronic cerebrospinal venous insufficiency

Figure 4

Contrast enhanced susceptibility weighted imaging (SWI) increases detection of signal hypointensities on SWI venography in patient with multiple sclerosis, in T2 lesions and normal appearing white matter [30]. Presented are pre-contrast (left), single dose post-contrast (middle) and triple dose post-contrast (right) images. The rows represent: a) high-pass filtered SWI, b) SWI phase mask, c) magnitude image multiplied 6 times by the phase mask, and d) minimum Intensity Projection image over 13 slices. Larger number and better defined signal hypointesities are detected with single and triple dose post-contrast SWI compared to pre-contrast SWI.
