Abstract
Focal cortical dysplasia (FCD) is a congenital developmental anomaly that is one of the leading causes of refractory epilepsy. MRI is an essential examination and T1WI, T2WI, and FLAIR images are commonly used MR sequences for delineating FCD.1 However, these MRI findings are often insufficiently clear. We experienced two FCD cases that were much better visualized by using T1WI with chemical shift selective (CHESS) than with T2WI and FLAIR images. CHESS is the most frequently used fat suppression pulse in clinical practice. We report two cases in which CHESS clearly demonstrated FCD, and compare the cases' pathology and MRI findings.
