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.

Refractory epilepsy is a condition characterized by epileptic seizure occurrence which cannot be controlled with antiepileptic drugs. This condition is associated with an excessive neuronal discharge produced by a group of neurons in a certain epileptogenic zone. Focal Cortical Dysplasia (FCD), usually found in these zones, was detected as one of the main causes of refractory epilepsy. In these cases, surgical intervention is necessary to minimize or eliminate the seizure occurrences. However, surgical treatment is only indicated in cases where there is complete certainty of the FCD. In order to assist neurosurgeons to detect precisely these regions, this paper aims to develop a classification method to detect FCD on MRI based on morphological and textural features from a voxel-level perspective. Multiple classifiers were tested throughout the extracted features, the best results achieved an accuracy of 91.76% using a Deep Neural Network classifier and 96.15% with J48 Decision Tree. The set of evaluating metrics showed that the results are promising.
