Abstract:
Objective To explore the value of high-resolution MRI in in the preoperative evaluation of children with type Ⅰ focal cortical dysplasia (FCD). Methods The MRI and related clinical data of 52 children with FCD Ⅰ confirmed by pathology were retrospectively analyzed,Compare the detection rates of major MRI signs of type Ⅰ FCD (focal demarcation of gray and white matter,focal cortical structure abnormalities,abnormal white matter signal lesions,and local atrophy / hypoplasia) of high-resolution imaging and conventional MRI sequences,and comparisons in the assessment of lesion extent,borders,and completeness were perfomed. Results The detection rate of high-resolution imaging for blurring of gray-white matter boundaries,focal cortical structural abnormalities,and abnormal white matter abnormalities was higher than that of conventional sequences (P<0.05),there was no significant difference in the detection rate of local atrophy/dysplasia (P>0.05). 3D-T1WI showed the range and boundary of the lesion better than the conventional T1WI sequence,3D-T2FLAIR was more complete than the conventional T2FLAIR sequence. Conclusion The high-resolution MRI could improve the detection rate of various major signs of type Ⅰ FCD,could more fully display the lesion and accurately assess the scope and boundary of the lesion,and was the preferred MRI imaging sequence before surgery.
