Abstract

Objective To investigate the application value analysis of MRI on hippocampal sclerosis of epileptic. Methods 23 cases with hippocampal sclerosis in our hospital from November 2013 to November 2014 were selected and were given MRI scan, FLAIR thin slice scan, T2W-FLAIR sequence, Travers GM-only, 3DT1W and 1H- MRS, analyze the application effect of MRI on hippocampal sclerosis of epileptic. Results MRI showed that hippocampal formation is clear, 23 cases on FSET1WI all had shrink hippocampus area, 20 cases showed unilateral hippocampus volum shrink (left side 11 cases, right side 9 cases), 3 cases showed hippocampus volum both sides shrink. In FLAIR sequence, 23 cases showed increased signal at hippocampal abnormality, in FSET2WI sequence, 19 cases showed increased signal at hippocampal abnormality, 4 cases had no obvious changes, 20 cases of head shallow ridges obvious disappear, 3 white matter atrophy, 1 temporal Angle enlargement, 2 temporal lobe shrink; In MRI image, hippocampal sclerosis showed surface hardening, temporal Angle enlargement, hippocampal signal abnormity elevator, hippocampus volum shirink, NAA declination. Conclusion MRI shows clear scan image of hippocampal sclerosis area, it can analyze anomalous change of biochemical metabolism and provide image data for clinical surgical positioning.
