2D turbo gradient- and spin-echo-BLADE diffusion-weighted imaging (DWI) was found to be superior to readout-segmented echo-planar-DWI and single-shot echo-planar-DWI in depicting and diagnosing cerebellopontine angle tumors.
Figure 1. A 50-year-old female with a left internal auditory canal acoustic neuroma (red arrows). The lesion is clearly visible on the TGSE-BLADE-DWI scans without geometric distortion, but with moderate and severe distortions on the RESOLVE-DWI and SS-EPI-DWI scans, respectively, interfering with lesion detection. Ghosting artifacts (white arrows) were absent at bone-air interfaces and anatomic structural identifications (blue arrows) were superior on the TGSE-BLADE-DWI scans compared with the other two DWI methods.
Table 3. A comparison of the subjective evaluation results among the three diffusion-weighted imaging methods.
