Susceptibility weighted imaging: Clinical applications and future directions

Figure 12 A 68-year-old woman with right lenticulostriate acute infarct. A: DWI reveals high signal intensity lesion in the right caudate nucleus head and lentiform nucleus region; B: ADC map shows restricted diffusion consistent with an acute infarct; C: Non-contrast CT image, hyperdense artery sign is seen along the right MCA artery; D: SWI magnitude image shows susceptibility vessel sign in the same region corresponding to the CT image indicating an acute thrombus. SWI: Susceptibility weighted imaging; DWI: Diffusion weighted image; ADC: Apparent diffusion coefficients; MCA: Middle cerebral artery.
