Abstract
We carried out 17 examinations to compare the utility of T2 (T2WIs) and diffusion-weighted (DWI) images for identification of cystic lesions in the cerebrospinal fluid space. Images were obtained at 1.0 T with T2sequence (TR/TE = 2500/140 ms) and followed by the same scan parameters with additional diffusion-gradient pulses (4 mT/m; b value 250s/mm2). After visual comparison of 17 images, signals of the lesion, cistern, ventricle and parenchyma were measured for statistical analysis in 10 of them. In the visual comparison, all lesions were isointense to adjacent CSF on T2WI, but in 15 out of 17 the contrast was much improved on DWI. The difference in signal intensities between the lesions and the CSF was statistically significant on DWI (P< 0.02), but insignificant on T2-weighted images (P>0.10). DWI can be more useful than T2WI in identification of cystic lesions in the CSF.
