Susceptibility weighted imaging: Clinical applications and future directions

Figure 6 A 62-year-old woman complaining of long-term headache attacks. A: Axial post-contrast T1W image shows contrast- enhanced dilated medullary veins which seem to converge into a dilated transcortical collector vein in the right periventricular region consistent with developmental venous anomaly; B: Axial SWI minIP image, has an excellent agreement with former image, revealing classical caput medusa appearance. SWI: Susceptibility weighted imaging; minIP: Minimum intensity projection algorithm.
