Description
Purpose
To evaluate the diagnostic value of susceptibility‐weighted imaging (SWI) for studying brain masses.
Materials and Methods
SWI is a high‐resolution, three‐dimensional, fully velocity‐compensated gradient‐echo sequence that uses both magnitude and phase data. Custom postprocessing is applied to enhance the contrast in the magnitude images between tissues with different susceptibilities. This sequence was applied to 44 patients (24 males and 20 females, 15–89 years old, mean age = 50.3 years) with brain masses, pre‐ and/or postcontrast, and compared with conventional sequences (T1, T1 postcontrast, T2, proton density (PD), fluid‐attenuated inversion recovery (FLAIR) and diffusion‐weighted imaging (DWI) at 1.5T). Correlation with pathology was obtained in 12 cases. All images were reviewed independently by three radiologists.

In the evaluation of tumor visibility, boundary …
