[Abstract] Focal cortical dysplasia (FCD) is one of the common causes of drug refractory epilepsy. Type Ⅰ accounts for 38.3% of the FCD lesions, while type Ⅱ accounts for 61.7%. Surgery is an effective way for the treatment of FCD. Preoperative detection and accurate localization of the lesions are important factors affecting the mode of operation and prognosis. At present, the diagnosis of FCD mainly depends on MRI. However, up to 40% of type Ⅱ FCD and 85% of type Ⅰ FCD lesions are negative on conventional MRI, which brings great difficulty to diagnosis and operation. With the development of MRI hardware, software and post-processing technology, the negative detection rate of FCD in conventional MRI is greatly improved (overall diagnostic gain rate 31%). Which is great significance for accurate location of lesions, guiding surgery and reducing postoperative seizures. Therefore, this paper reviews the research progress of improving the detection methods of FCD negative on conventional MRI.
