Susceptibility weighted imaging: Clinical applications and future directions

Figure 4 A 21-year-old man with left frontal cavernous malformation. A: On the axial FSE T2W image, a left frontal cavernous malformation is seen with typical pop-corn appearance, surrounded by a thick hemosiderin rim; B: SWI shows prominent blooming artİfact due to paramagnetic effect. Another patient is a 39-year-old man with left cerebellar tonsil cavernous malformation; C: Axial FSE T2W image, clearly depicts the cavernous malformation consisting of a high signal intensity core and a peripheric low signal intensity hemosiderin; D: On SWI, the lesion is more conspicuous. Note how the brighter central areas on the T2WI are obscured by the susceptibility artifact. SWI: Susceptibility weighted imaging; FSE: Fast spin echo.
